As the 1970s came to a ^ close, a series of head- line stories gave Americans a look at the dangers of dumping indus- trial and urban wastes on the land. First there was New York's Love Canal. Hazard- ous waste buried there over a 25-year period contaminated streams and soil, and endan- gered the health of nearby residents. The result: evacu- ation of several hundred people. Then the leaking barrels at the Valley of the Drums in Kentucky attracted public attention, as did the dioxin tainted land and water in Times Beach, Missouri. In all these cases, human health and the environment were threatened, lives were disrupted, property values depreciated. It became in- creasingly clear that there were large numbers of serious hazardous waste problems that were falling through the cracks of existing environ- mental laws. The magnitude of these emerging problems moved Congress to enact the Comprehensive Environ- mental Response, Compensa- tion, and Liability Act in 1980. CERCLA — commonly known as the Superfund -— was the first Federal law established to deal with the dangers posed by the Nation's hazardous waste sites. After Discovery, the Problem Intensified Few realized the size of the problem until EPA began the process of site discovery and site.evaluation. Not hun- dreds, but thousands of potential hazardous waste sites existed, and they pre- sented the Nation with some of the most complex pollution problems it had ever faced. In the 10 years since the Superfund program began, hazardous waste has surfaced as a major environmental concern in every part of the United States. It wasn't just the land that was contami- nated by past disposal prac- tices. Chemicals in the soil were spreading into the groundwater (a source of drinking water for many) and into streams, lakes, bays, and wetlands. Toxic vapors contaminated the air at some sites, while at others improp- erly disposed or stored wastes threatened the health of the surrounding commu- nity and the environment. EPA Identified More than 1,200 Serious Sites EPA has identified 1,236 hazardous waste sites as the most serious in the Nation. These sites comprise the "National Priorities List": sites targeted for cleanup under the Superfund. But site discoveries continue, and EPA estimates that, while some will be deleted after lengthy cleanups, this list, commonly called the NPL, will continue to grow by ap- proximately 100 sites per year, reaching 2,100 sites by the year 2000. THE NATIONAL CLEANUP EFFORT IS MUCH MORE THAN THE NPL From the beginning of the program, Congress recog- nized that the Federal govern- ment could not and should not address all environmental problems stemming from past disposal practices. Therefore, the EPA was directed to set priorities and establish a list of sites to target. Sites on the NPL (1,236) are thus a rela- 111 ------- lively small subset of a larger inventory of potential hazard- ous waste sites, but they do comprise the most complex and environmentally compel- ling cases. EPA has logged more than 32,000 sites on its National hazardous waste inventory, and assesses each site within one year of being logged. In fact, over 90 per- cent of the sites on the inven- tory have been assessed. Of the assessed sites, 55 percent have been found to require no further Federal action because they did not pose significant human health or environ- mental risks. The remaining sites are undergoing further assessment to determine if long-term Federal cleanup activities are appropriate. EPA IS MAKING PROGRESS ON SITE CLEANUP The goal of the Superfund program is to tackle immedi- ate dangers first, and then move through the progressive steps necessary to eliminate any long-term risks to public health and the environment. The Superfund responds immediately to sites posing imminent threats to human health and the environment at both NPL sites and sites not on the NPL. The purpose is to stabilize, prevent, or temper the effects of a haz- ardous release, or the threat of one. These might include tire fires or transportation accidents involving the spill of hazardous chemicals. Because they reduce the threat a site poses to human health and the environment, immediate cleanup actions are an integral part of the Superfund program. Immediate response to immi- nent threats is one of the Superfund's most noted achievements. Where immi- nent threats to the public or environment were evident, EPA has completed or moni- tored emergency actions that attacked the most serious threats to toxic exposure in more than 1,800 cases. The ultimate goal for a haz- ardous waste site on the NPL is a permanent solution to an environmental problem that presents a serious (but not an imminent) threat to the public or environment. This often requires a long-term effort. In the last four years, EPA has aggressively accelerated its efforts to perform these long- term cleanups of NPL sites. More cleanups were started in 1987, when the Superfund law was amended, than in any previous year. And in 1989 more sites than ever reached the construction stage of the Superfund cleanup process. Indeed construction starts increased by over 200 percent between late 1986 and 1989! Of the sites currently on the NPL, more than 500 — nearly half — have had construction cleanup activity. In addition, over 500 more sites are pres- ently in the investigation stage to determine the extent of site contamination, and to identify appropriate cleanup remedies. Many other sites with cleanup remedies se- lected are poised for the start of cleanup construction activ- ity. Measuring success by "progress through the cleanup pipeline," EPA is clearly gaining momentum. EPA MAKES SURE CLEANUP WORKS EPA has gained enough experience in cleanup con- struction to understand that environmental protection does not end when the rem- edy is in place. Many com- plex technologies — like those designed to clean up ground water — must operate for many years in order to accomplish their objectives. EPA's hazardous waste site managers are committed to proper operation and mainte- nance of every remedy con- structed. No matter who has been delegated responsibility for monitoring the cleanup work, the EPA will assure that the remedy is carefully followed and that it continues to do its job. Likewise, EPA does not abandon a site even after the cleanup work is done. Every IV ------- five years the Agency reviews each site where residues from hazardous waste cleanup still remain to ensure that public and environmental health are still being safeguarded. EPA will correct any deficiencies discovered and report to the public annually on all five- year reviews conducted that year. CITIZENS HELP SHAPE DECISIONS Superfund activities also depend upon local citizen participation. EPA's job is to analyze the hazards and deploy the experts, but the Agency needs citizen input as it makes choices for affected communities. Because the people in a community with a Superfund site will be those most di- rectly affected by hazardous waste problems and cleanup processes, EPA encourages citizens to get involved in cleanup decisions. Public in- volvement and comment does influence EPA cleanup plans by providing valuable infor- mation about site conditions, community concerns and preferences. This State volume and the companion National Over- view volume provide general Superfund background information and descriptions of activities at each State NPL site. These volumes are intended to clearly describe what the problems are, what EPA and others participating in site cleanups are doing, and how we as a Nation can move ahead in solving these serious problems. USING THE STATE AND NATIONAL VOLUMES IN TANDEM To understand the big picture on hazardous waste cleanup, citizens need to hear about both environmental progress across the country and the cleanup accomplishments closer to home. The public should understand the chal- lenges involved in hazardous waste cleanup and the deci- sions we must make — as a Nation —: in finding the best solutions. The National Overview volume — Superfund: Focus- ing on the Nation at Large — accompanies this State vol- ume. The National Overview contains important informa- tion to help you understand the magnitude and challenges facing the Superfund pro- gram as well as an overview of the National cleanup effort. The sections describe the nature of the hazardous waste problem nationwide, threats and contaminants at NPL sites and their potential effects on human health and the environment, the Super- fund program's successes in cleaning up the Nation's serious hazardous waste sites, and the vital roles of the various participants in the cleanup process. This State volume compiles site summary fact sheets on each State site being cleaned up under the Superfund program. These sites repre- sent the most serious hazard- ous waste problems in the Nation, and require the most complicated and costly site solutions yet encountered. Each State book gives a "snapshot" of the conditions and cleanup progress that has been made at each NPL site in the State through the first half of 1990. Conditions change as our cleanup efforts continue, so these site summaries will be updated periodically to include new information on progress being made. To help you understand the cleanup accomplishments made at these sites, this State volume includes a description of the process for site discov- ery, threat evaluation and long-term cleanup of Super- fund sites. This description — How Does the Program Work to Clean Up Sites? — will serve as a good reference point from which to review the cleanup status at specific sites. A glossary also is included at the back of the book that defines key terms used in the site fact sheets as they apply to hazardous waste management. ------- VI ------- The diverse problems posed by the Nation's hazardous waste sites have provided EPA with the challenge to establish a consistent approach for evaluating and cleaning up the Nation's most serious sites. To do this, EPA had to step beyond its traditional role as a regulatory agency to develop processes and guidelines for each step in these technically complex site cleanups. EPA has established proce- dures to coordinate the efforts of its Washington, D.C. Head- quarters program offices and its front-line staff in 10 Regional Offices with the State governments, contractors, and private parties who are participating in site cleanup. An important part of the process is that any time during cleanup, work can be led by EPA or the State or, under their monitoring, by private parties who are potentially responsible for site con- tamination. The process for discovery of the site, evaluation of threat, and long-term cleanup of Superfund sites is summarized in the following pages. The phases of each of these steps are high- lighted within the description. The flow diagram below pro- vides a summary of this three step process. STEP1 Discover site and determine whether an emergency exists * STEP 2 Evaluate whether a site is a serious threat to public health or environment STEPS Perform long-term cleanup actions on the most serious hazardous waste sites in the Nation '' Emergency actions are performed whenever needed in this three-step process FIGURE 1 Although this State book provides a current "snapshot" of site progress made only by emer- gency actions and long-term cleanup actions at Superfund sites, it is important to understand the discovery and evaluation process that leads up to identifying and cleaning up these most serious uncontrolled or abandoned hazardous waste sites in the Nation. This discovery and evaluation process is the starting point for this summary description. vii ------- plow does. !!A learn. I about potential Unhazardous waste^x _", J" ts'ites? IjJV' STEP 1: SITE DISCOVERY AND EMERGENCY EVALUATION Site discovery occurs in a number of ways. Information comes from concerned citizens — people may notice an odd taste or foul odor in their drinking water, or see half-buried leaking barrels; a hunter may come across a field where waste was dumped illegally. Or there may be an explosion or fire which alerts the State or local authorities to a problem. Rou- tine investigations by State and local governments, and re- quired reporting and inspection of facilities that generate, treat, store, or dispose of hazardous waste also help keep EPA informed about either actual or potential threats of hazardous substance releases. All reported sites or spills are recorded in the Superfund inventory (CERCLIS) for further investigation to determine whether they will require cleanup. £ What happens If I there Is an j I-danger? IT; As soon as a potential hazardous waste site is reported, EPA determines whether there is an emergency requiring an imme- diate cleanup action. If there is, they act as quickly as possible to remove or stabilize the imminent threat. These short-term emergency actions range from building a fence around the contaminated area to keep people away or temporarily relo- cating residents until the danger is addressed, to providing bottled water to residents while their local drinking water supply is being cleaned up, or physically removing wastes for safe disposal. However, emergency actions can happen at any time an imminent threat or emergency warrants them — for example, if leaking barrels are found when cleanup crews start digging in the ground or if samples of contaminated soils or air show that there may be a threat of fire or explosion, an immediate action is taken. I If there isnt an E imminent danger, Show does EPA determine what, if , any^ cleanup actions, I should be STEP 2: SITE THREAT EVALUATION Even after any imminent dangers are taken care of, in most cases contamination may remain at the site. For example, residents may have been supplied with bottled water to take care of their immediate problem of contaminated well water. But now it's time to figure out what is contaminating the drinking water supply and the best way to clean it up. Or vni ------- EPA may determine that there is no imminent danger from a site, so now any long-term threats need to be evaluated. In either case, a more comprehensive investigation is needed to determine if a site poses a serious but not imminent danger, and requires a long-term cleanup action. Once a site is discovered and any needed emergency actions are taken, EPA or the State collects all available background information not only from their own files, but also from local records and U.S. Geological Survey maps. This information is used to identify the site and to perform a preliminary assess- ment of its potential hazards. This is a quick review of readily available information to answer the questions: • Are hazardous substances likely to be present? • How are they contained? • How might contaminants spread? • How close is the nearest well, home, or natural resource area like a wetland or animal sanctuary? • What may be harmed — the land, water, air, people, plants, or animals? Some sites do not require further action because the prelimi- nary assessment shows that they don't threaten public health or the environment. But even in these cases, the sites remain listed in the Superfund inventory for record keeping purposes and future reference. Currently, there are more than 32,000 sites maintained in this inventory. Inspectors go to the site to collect additional information to evaluate its hazard potential. During this site inspection, they look for evidence of hazardous waste, such as leaking drums and dead or discolored vegetation. They may take some samples of soil, well water, river water, and air. Inspectors analyze the ways hazardous materials could be polluting the environment — such as runoff into nearby streams. They also check to see if people (especially children) have access to the site. assessment siows : that k setiaas ihtreat exist what's Information collected during the site inspection is used to identify the sites posing the most serious threats to human health and the environment.

The HRS is .the scoring system EPA uses to assess the relative threat from a release or a potential release of hazardous substances from a site to surrounding groundwater, surface water/ air, and soil. A site score is based on the likelihood a hazardous substance will be released from the site, the toxicity and amount of hazardous substances at the site, and the people and sensitive environments potentially affected by contamination at the site. Only sites with high enough health and environmental risk scores are proposed to be added to EPA's National Priorities List (NPL). That's why there are 1,236 sites are on the NPL, but there are more than 32,000 sites in the Superfund inven- tory. Only NPL sites can have a long-term cleanup paid for from the national hazardous waste trust fund —- the Super- fund. But the Superfund can and does pay for emergency actions performed at any site, whether or not it's on the NPL. The public can find out whether a site that concerns them is on the NPL by calling their Regional EPA office at the number listed in this book. The proposed NPL identifies sites that have been evaluated through the scoring process as the most serious problems among uncontrolled or abandoned hazardous waste sites in the U.S. In addition, a site will be added to the NPL if the Agency for Toxic Substances and Disease Registry issues a health advisory recommending that people be moved away from the site. Updated at least once a year, it's only after public comments are considered that these proposed worst sites are officially added to the NPL. Listing on the NPL does not set the order in which sites will be cleaned up. The order is influenced by the relative priority of the site's health and environmental threats compared to other sites, and such factors as State priorities, engineering capabili- ties, and available technologies. Many States also have their own list of sites that require cleanup; these often contain sites not on the NPL that are scheduled to bd cleaned up with State money. And it should be said again that any emergency action needed at a site can be performed by the Superfund whether or not a site is on the NPL. ------- STEP 3: LONG-TERM CLEANUP ACTIONS The ultimate goal for a hazardous waste site on the NPL is a permanent, long-term cleanup. Since every site presents a unique set of challenges, thefe'is no single all-purpose solu- tion. So a five-phase "remedial response" process is used to develop consistent and workable solutions to hazardous waste problems across the Nation: 1. Investigate in detail the extent of the site contamination: remedial investigation, 2. Study the range of possible cleanup remedies: feasibility study, 3. Decide .which remedy to use: Record of Decision or ROD, 4. Plan the remedy, remedial design, and 5. Carry out the rernedy: remedial action. This remedial response process is a long-term effort to provide a permanent solution to an environmental problem that presents a serious, but not an imminent threat to the public or environment. The first two phases of a.long-term cleanup are a combined remedial investigation and feasibility study (RI/FS) that determine the nature and extent of contamination at the site, and identify and evaluate cleanup alternatives. These studies may be conducted by EPA or the State or, under their monitor- ing, by private parties. , Like the initial site inspection described earlier, a remedial investigation involves an examination of site data in order to better define the problem,. But the remedial investigation is much more detailed and .comprehensive than the initial site inspection. .'..',.'- , A remedial investigation can best be described as a carefully designed field study. It includes extensive sampling and laboratory analyses to generate more precise data on the types and quantities of wastes present at the site, the type of soil and water drainage patterns, and specific human health and environmental risks. The result is information that allows EPA to select the cleanup strategy that is best suited to a particular site or to determine that no cleanup is needed. a-site Js are -• slips to e-1-eamip? ,'> .-v .-4 & J-.JV f fff : •**/,; A XI ------- Placing a site on the NPL does not necessarily mean that cleanup is needed. It is possible for a site to receive an HRS score high enough to be added to the NPL, but not ultimately require cleanup actions. Keep in mind that the purpose of the scoring process is to provide a preliminary and conservative assessment of potential risk. During subsequent site investiga- tions, the EPA may find either that there is no real threat or that the site does not pose significant human health or envi- ronmental risks. How are cleanup alternatives identified and * evaluated? EPA or the State or, under their monitoring, private parties identify and analyze specific site cleanup needs based on the extensive information collected during the remedial investiga- tion. This analysis of cleanup alternatives is called a feasibility study. Since cleanup actions must be tailored exactly to the needs of each individual site, more than one possible cleanup alterna- tive is always considered. After making sure that all potential cleanup remedies fully protect human health and the environ- ment and comply with Federal and State laws, the advantages and disadvantages of each cleanup alternative are carefully compared. These comparisons are made to determine their effectiveness in the short- and long-term, their use of perma- nent treatment solutions, and their technical feasibility and cost. To the maximum extent practicable, the remedy must be a permanent solution and use treatment technologies to destroy principal site contaminants. But remedies such as containing the waste on, site or removing the source of the problem (like leaking barrels) are often considered effective. Often special pilot studies are conducted to determine the effectiveness and feasibility of using a particular technology to clean up a site. Therefore, the combined remedial investigation and feasibility study can take between 10 and 30 months to complete, de- pending on the size and complexity of the problem. j Does the public have i a say in the final : cleanup decision? Yes. The Superfund law requires that the public be given the opportunity to comment on the proposed cleanup plan. Their concerns are carefully considered before a final decision is made. Xll ------- The results of the remedial investigation and feasibility study, which also point out the recommended cleanup choice, are published in a report for public review and comment. EPA or the State encourages the public to review the information and take an active role in the final cleanup decision. Fact sheets and announcements in local papers let the community know where they can get copies of the study and other reference documents concerning the site. The public has a minimum of 30 days to comment on the proposed cleanup plan after it is published. These comments can either be written or given verbally at public meetings that EPA or the State are required to hold. Neither EPA nor the State can select the final cleanup remedy without evaluating and providing written answers to specific community com- ments and concerns. This "responsiveness summary" is part of EPA's write-up of the final remedy decision, called the Record of Decision or ROD. The ROD is a public document that explains the cleanup remedy chosen and the reason it was selected. Since sites frequently are large and must be cleaned up in stages, a ROD may be necessary for each contaminated resource or area of the site. This may be necessary when contaminants have spread into the soil, water and air, and affect such sensitive areas as wetlands, or when the site is large and cleaned up in stages. This often means that a number of remedies using different cleanup technologies are needed to clean up a single site. Yes. Before a specific cleanup action is carried out, it must be designed in detail to meet specific site needs. This stage of the cleanup is called the remedial design. The design phase provides the details on how the selected remedy will be engineered and constructed. Projects to clean up a hazardous waste site may appear to be like any other major construction project but, in fact, the likely presence of combinations of dangerous chemicals demands special construction planning and procedures. Therefore, the design of the remedy can take anywhere from 6 months to 2 years to complete. This blueprint for site cleanup includes not only the details on every aspect of the construction work, but a description of the types of hazardous wastes expected at the -If eyerg cleamtp " , v- action needs Ip,bet s " ^ilored to a sbe^ dbes tlbe deslgit of Ifee _ma.edy tieed to tailoted too? - xiii ------- site, special plans for environmental protection, worker safety, regulatory compliance, and equipment decontamination. |" Once the design is * complete, how long r does it take to ^ | actually clean up We t site and how much x; r does it cost? ^ ,; v.

In a few cases, the only action needed may be to remove drums of hazardous waste and decontaminate them -— an action that takes limited time and money. In most cases, however, a remedial action may involve different and expen- sive measures .that can take a long time. For example, cleaning polluted groundwater or dredging contaminated river bottoms can take several years of complex engineering work before contamination is reduced to safe levels. Sometimes the selected cleanup remedy described in the ROD may need to be modified because of new contami- nant information discovered or difficulties that were faced during the early cleanup activities. Taking into account these differences, a remedial cleanup action takes an average of 18 months to complete and costs an average of $26 million per site. No. The deletion of a site from the NPL is anything but auto- matic. For example, cleanup of contaminated groundwater may take up to 20 years or longer. Also, in some cases the long-term monitoring of the remedy is required to ensure that it is effective. After construction of certain remedies, opera- tion and maintenance (e.g., maintenance of ground cover, groundwater monitoring, etc.) or continued pumping and treating of groundwater, may be required to ensure that the remedy continues to prevent future health hazards or environ- mental damage, and ultimately meets the cleanup goals specified in the ROD. Sites in this final monitoring or opera- tional stage of the cleanup process are designated as "con- struction completed". It's not until a site cleanup meets all the goals and monitoring requirements of the selected remedy that EPA can officially propose the site for "deletion" from the NPL. And it's not until public comments are taken into consideration that a site can actually be deleted from the NPL. Deletions that have occurred are included in the "Construction Complete" cate- gory in the progress report found later in this book. XIV ------- Yes. Based on the belief that "the polluters should pay/' after a site is placed on the NPL, the EPA makes a thorough effort to identify and find those responsible for causing contamination problems at a site. Although EPA is willing to negotiate with these private parties and encourages voluntary cleanup, it has the authority under the Superfund law to legally force those potentially responsible for site hazards to take specific cleanup actions. All work performed by these parties is closely guided and monitored by EPA, and must meet the same standards required for actions financed through the Superfund. Because these enforcement actions can be lengthy, EPA may decide to use Superfund monies to make sure a site is cleaned up without unnecessary delay. For example, if a site presents an imminent threat to public health and the environment, or if conditions at a site may worsen, it could be necessary to start the cleanup right away. Those responsible for causing site contamination are liable under the law for repaying the money EPA spends in cleaning up the site. Whenever possible, EPA and the Department of Justice use their legal enforcement authorities to require responsible parties to pay for site cleanups, thereby preserving the Super- fund for emergency actions and sites where no responsible parties can be identified. for tlte ..5' ?•••«•.•.•.•<. XV ------- TAX ------- The Site Fact Sheets % presented in this book - are comprehensive summaries that cover a broad range of information. The fact sheets describe hazard- ous waste sites on the Na- tional Priorities List (NPL) and their locations, as well as the conditions leading to their listing ("Site Description"). They list the types of con- taminants that have been dis- covered and related threats to public and ecological health ("Threats and Contami- nants"). "Cleanup Ap- proach" presents an overview of the cleanup activities completed, underway, or planned. The fact sheets conclude with a brief synop- sis of how much progress has been made on protecting public health and the envi- ronment. The summaries also pinpoint other actions, such as legal efforts to involve pol- luters responsible for site contamination and commu- nity concerns. The following two pages show a generic fact sheet and briefly describes the informa- tion under each section. The square "icons" or symbols ac- companying the text allow the reader to see at a glance which environmental re- sources are affected and the status of cleanup activities. Icons in the Threats and Contaminants Section Contaminated Groundwater re- sources in the vicinity or underlying the site. (Groundwater is often used as a drinking water source.) Contaminated Sur- face Water and Sediments on or near the site. (These include lakes, ponds, streams, and rivers.) Contaminated Air in the vicinity of the site. (Pollution is usually periodic and involves contaminated dust particles or hazardous gas emissions.) Contaminated Soil and Sludges on or near the site. Threatened or contaminated Envi- ronmentally Sensi- tive Areas in the vicinity of the site. (Examples include wetlands and coastal areas, critical habitats.) Icons in the Response Action Status Section Actions have been taken or are underway to eliminate immediate threats at the site. Site Studies at the site are planned or underway. Remedy Selected indicates that site investigations have been concluded and EPA has se- lected a final cleanup remedy for the site or part of the site. Remedy Design means that engi- neers are prepar- ing specifications and drawings for the selected cleanup technologies. Cleanup Ongoing indicates that the selected cleanup remedies for the contaminated site — or part of the site — are currently underway. Cleanup Complete shows that all cleanup goals have been achieved for the contaminated site or part of the site. xvii ------- Site Responsibility Identifies the Federal, State, and/or potentially responsible parties that are taking responsibility for cleanup actions at the site.

You can use this book to keep informed about the sites that concern you, particularly ones close to home. EPA is committed to involving the public in the decisionmaking process associated with hazardous waste cleanup. The Agency solicits input from area residents in com- munities affected by Super- fund sites. Citizens are likely to be affected not only by hazardous site conditions, but also by the remedies that combat them. Site cleanups take many forms and can affect communities in differ- ent ways. Local traffic may be rerouted, residents may be relocated, temporary water supplies may be necessary. Definitive information on a site can help citizens sift through alternatives and make decisions. To make good choices, you must know what the threats are and how EPA intends to clean up the site. You must understand the cleanup alternatives being proposed for site cleanup and how residents may be af- fected by each one. You also need to have some idea of how your community intends to use the site in the future and to know what the com- munity can realistically expect once the cleanup is complete. EPA wants to develop cleanup methods that meet community needs, but the Agency can only take local concerns into account if it understands what they are. Information must travel both ways in order for cleanups to be effective and satisfactory. Please take this opportunity to learn more, become in- volved, and assure that hazardous waste cleanup at "your" site considers your community's concerns. xx ------- NPL Sites in State of Florida Florida is located in the southeast corner of the United States, and bordered by the Atlantic Ocean on the east, the Gulf of Mexico to the west, and Georgia and Alabama to the north. The State covers 58,664 square miles consisting primarily of flat lime- stone pennisula.

For example, separate cleanup efforts may be required to address the source of the contamination, hazardous substances in the groundwater, and surface water pollution, or to clean up different areas of a large site. In such cases, the chart portrays cleanup progress at the site's most advanced stage, reflecting the status of site activities rather than administrative accomplishments. *- An arrow in the "Initial Response" category indicates that an emergency cleanup or initial action has been completed or is currently underway. Emergency or initial actions are taken as an interim measure to provide immediete relief from exposure to hazardous site conditions or to stabilize a site to prevent further contamination. *- An arrow in the "Site Studies" category indicates that an investigation to determine the nature and extent of the contamination at the site is currently ongoing or planned to begin in 1991. •*- An arrow in the "Remedy Selection" category means that the EPA has selected the final cleanup strategy for the site. At the few sites where the EPA has determined that initial response actions have eliminated site contamination, or that any remaining contamination will be naturally dispersed without further cleanup activities, a "No Action" remedy is selected. In these cases, the arrows in the Progress Report are discontinued at the "Remedy Selection" step and resume in the final "Construction Complete" category- •K An arrow at the "Remedial Design" stage indicates that engineers are currently designing the technical specifications for the selected cleanup remedies and technologies. «*- An arrow marking the "Cleanup Ongoing" category means that final cleanup actions have been started at the site and are currently underway. *• A arrow in the "Construction Complete" category is used only when all phases of the site cleanup plan have been performed and the EPA has determined that no additional construction actions are required at the site. Some sites in this category may currently be undergoing long-term pumping and treating of groundwater, operation and maintenance or monitoring to ensure that the completed cleanup actions continue to protect human health and the environment. The sites are listed in alphabetical order. Further information on the activities and progress at each site is given in the site "Fact Sheets" published in this volume. xxiii ------- IT* Page 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 ugrcss luwcuu. vsjicei She Name AGRICO CHEMICAL AIRCO PLATING CO., INC.

Industrial activity on the site began in 1889, when a company started producing sulfuric ac/c/from iron pyrite. Around 1920, American Agriculture Chemical Company began making fertilizer from phosphate rock. The plant underwent numerous ownership changes and its name was changed to Agrico. In 1975, Agrico stopped production, tore down the buildings, and sold the land. All that remains on the site are the foundations of five buildings, including a plant where phosphate was processed to make fluorine. Four ponds that were used to store liquid manufacturing wastes lie to the north and east of the ruins. In 1958, a municipal water well 1 1/4 miles from the site was closed due to high acidity and fluoride concentrations. The primary aquifer under the site is highly permeable, which facilitates the movement of contaminants into the groundwater. Given the direction of the flow, any contamination could enter Bayou Texar or Pensacola Bay. Thirteen county wells serving approximately 114,000 people lie within 3 miles of the site. Few residents live in the immediate vicinity of the site. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 06/24/88 Final Date: 10/04/89 n Threats and Contaminants The groundwater, soil, and surface water are contaminated with lead, sulfuric acid, and fluorides, probably as a result of pipe and tank corrosion from sulfuric acid. There is a potential for the well water to become contaminated because of groundwater migration, which would pose a threat to individuals who use the wells for their water supply. Cleanup Approach This site is being addressed in a single long-term remedial phase focusing on water pollution at the site. March 1990 NPL HAZARDOUS WASTE SITES 1 continued ------- AGRICO CHEMICAL Response Action Status Water Pollution: Under EPA monitoring, the parties potentially, responsible for site contamination began an intensive study of site problems in 1989. This investigation will determine the nature and extent of water pollution and will recommend the best strategies for final cleanup. It is slated for completion in mid-1991. ! Environmental Progress After adding this site to the NPL, the EPA performed preliminary investigations and determined that no immediate actions were needed at the Agrico Chemical site since the contaminated well was already closed. Further investigations into cleanup strategies are taking place. ------- AIRCO PLATING COMPANY, INC. FLORIDA EPA ID# FLD004145140 REGION 4 CONGRESSIONAL DIST. 18 Dade County Miami Site Description The 1 1/2-acre Airco Plating Company, Inc. site has operated as an electroplating shop since 1957. Nickel, cadmium, chromium, copper, and zinc plating are the chief processes. Before 1973, operators disposed of plating wastes, including sludge, in three on-site seepage ponds. Since 1973, treated wastes have been released to the Miami sewage system. Since 1982, workers have separated out the sludges and shipped them to an EPA-approved hazardous waste facility. During a 1985 investigation, the EPA discovered that one of the likely waste disposal areas had been covered with asphalt pavement and a lawn. Soil and groundwater f rom near the ponds contained contaminants associated with electroplating. The site lies over the recharge zone for the Biscayne Aquifer, which supplies drinking water for all of Dade County. Four municipal well fields supplying approximately 750,000 people are within 3 miles of the site. These wells are retrofitted with air strippers, because of contamination from a variety of sources. The site is located in a primarily industrial area about 1 mile north of the Miami International Airport. An estimated 6,500 people live within a 1-mile radius of the site. The Miami Canal, which flows into the Miami River, is located about 1/2 mile from the site. Site Responsibility: This site is being addressed through Federal and potentially responsible parties'actions. IMPL LISTING HISTORY Proposed Date: 06/24/88 Final Date: 02/21/90 Threats and Contaminants Shallow groundwater in the areas of the ponds, surface and subsurface soil near the ponds, and the lawn area between the ponds are contaminated with heavy metals including cadmium, chromium, copper, and nickel from former electroplating operations. The individuals who are most at risk of contact with contaminated soils are workers conducting cleanup activities at the site. People who use the groundwater in this area could potentially be exposed to heavy metals. March 1990 NPL HAZARDOUS WASTE SITES 3 continued ------- AIRCO PLATING COMPANY, INC. Cleanup Approach The site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site. Response Action Status Entire Site: The parties potentially responsible for the contamination of the site began an intensive study of soil and water contamination in 1989. This investigation will explore the nature and extent of pollution at the site and will recommend the best strategies for final cleanup. It is slated for completion at the end of 1990. Negotiations are also planned with the parties potentially responsible to conduct additional studies and cleanup activities. Environmental Progress The EPA performed preliminary site investigations and determined that with air strippers on municipal wells, there are no immediate threats at the Airco Plating Company site while the parties potentially responsible for site contamination complete further investigations and cleanup activities. ------- ALPHA CHEM CORPORATIO FLORIDA EPA ID# FLD041495441 REGION 4 CONGRESSIONAL DIST. 10 Polk County Kathleen, 3 miles north of Lakeland Alias: Alpha Resins Corporation Site Description The Alpha Resins Corporation (ARC), formerly known as Alpha Chemical Corporation, is a wholly-owned subsidiary of the Alpha Corporation of Tennessee and has produced unsaturated polyester resin for fiberglass manufacturers at this 32-acre site since 1967. The process yields wastewater containing small amounts of volatile organic compounds (VOCs). Under a State permit, the company disposed of this waste in two unlined surface ponds, (Pond #4 and #3-2) relying on natural biological processes to break down the organics. In 1976, ARC began incinerating the wastewater instead. Pond #4 dried up, and workers used the area as a solid waste landfill for a year, covering it with soil in 1977. in 1977, Pond #3-2 was divided, and sludge waters were pumped from #2 to #3. Pond #2 was lined with concrete to receive wastewater. No waste was discharged from Pond #2, and this was covered with soil in 1988. In 1982, when ARC sought to line Pond #3 with concrete for caustic wash water disposal, the Florida Department of Environmental Regulations (FDER) requested groundwater monitoring information. New monitoring wells revealed contamination of the surficial aquifer. Of the 23 organic compounds detected, ethyl benzene occurred most often and in the highest concentrations. The area around the site is residential and commercial. Approximately 650 people live within 1/2 mile of the site. Twenty feet of clay shield the Floridian Aquifer from contaminated groundwater; this aquifer, which provides drinking water for area residents, is not polluted. Surface water from the site drains into a vegetated, low-lying wetland. Site Responsibility: This site is being addressed through Federal, State, and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Threats and Contaminants The groundwater, sediments, and soil were found to be contaminated with VOCs, mainly ethyl benzene and xylene from former process wastes. There is no health threat at this time since the surficial aquifer is not used for drinking water and no contamination has been detected in the deeper Floridian aquifer. March 1990 NPL HAZARDOUS WASTE SITES 5 continued ------- ALPHA CHEMICAL CORPORATION Cleanup Approach The site is being addressed in a long-term remedial phase focusing on cleanup of the entire site. Response Action Status Entire Site: The EPA selected a cleanup remedy for this site in 1988 which features capping the small unlined Pond #3 to keep rainwater and runoff from spreading contaminants and long-term monitoring of groundwater and surface water to assure the effectiveness of cleanup. The parties responsible for contamination at the site conducted the engineering design and began cleanup activities in 1989. Construction of the cap was completed later that year and sampling of the groundwater and surface water is ongoing. Monitoring of groundwater and surface water samples will continue every 3 months. Site Facts: A Consent Decree was signed in 1989 by the State and the parties potentially responsible for the site contamination. Environmental Progress Cleanup activities are completed at the Alpha Chemical site and monitoring of groundwater and surface water will continue to ensure the effectiveness of the remedy and safe conditions for nearby residents and the environment. ------- AMERICAN CREOSOTE FLORIDA EPA ID# FLD008161994 REGION 4 CONGRESSIONAL DIST. 01 Escambia County Pensacola Site Description The 18-acre American Creosote Works site is an inactive wood-treating facility in Pehsgcola, located about 1/4 mile north of the confluence of Bayou Chico and Pensacola Bay. It operated from the early 1900s until 1982, when the company filed for bankruptcy. Workers treated poles with creosote before 1950, when they began using pentachlorophenol (PCP) with increasing regularity. Operators discharged liquid process wastes into two unlined, 80,000-gallon percolation ponds. Before 1970, these wastewaters were allowed to overflow through a spillway and follow a drainage course into Bayou Chico and Pensacola Bay. Later, workers drew wastewaters off the ponds periodically and discharged them into designated "spillage areas" on site. Additional discharges occurred when heavy rainfall flooded the ponds, which then overflowed their dikes. The site lies in a commercial and residential area. Withdrawal wells may serve as a conduit between the shallow and deeper aquifer. No drinking water wells lie within the area of known contamination. , , • Site Responsibility: This site is being addressed through Federal actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Threats and Contaminants Major contaminants in the soil and groundwater are volatile organic compounds (VOCs) and creosotes such as polyaromatic hydrocarbons (PAHs) from the former wood-treating processes. PAHs were also found in one sample of sediments from the drainage ditch. Additional bay and biota sampling are needed to assess the impact on biota living in the bay sediments. The most significant transport route for contaminants is by groundwater from the sludge lagoons to Pensacola Bay. Minor exposure routes for people include breathing dust on the site and accidentally ingesting or touching contaminated soils. March 1990 NPL HAZARDOUS WASTE SITES 7 continued ------- AMERICAN CREOSOTE WORKS Cleanup Approach This site is being addressed in three stages: emergency actions and two long-term remedial phases focusing on soil cleanup and groundwater, sludge, and underlying soils cleanup. Response Action Status Emergency Actions: The EPA undertook several emergency actions at this site. In 1983, workers drained, treated, and discharged contaminated water in the on-site ponds, solidifying the remaining sludge and temporarily capping this solidified material with a layer of clay to keep rainfall and runoff from spreading contaminants. In 1984, they staged the drums on the site and built a fence around them. In 1985 and 1986, the cap was repaired and workers installed a fence around the capped area. Soil Cleanup: The EPA's remedies for soil cleanup include: (1) excavating, screening, and stockpiling the contaminated surface soil; (2) treating the contamination with bioremediation {the selected type of bioremediation, landfarming or slurry, will be determined based on the results of treatability studies); (3) replacing the excavated and treated soils on site; (4) removing debris; (5) repairing the fence; (6) properly disposing of drilling muds; and (7) repairing the existing clay cap. The EPA began the engineering design for soil biotreatment in 1989. Soil excavation activities began later the same year. Treatment of the contaminated soils is scheduled to begin in 1991. . remedies. Groundwater, Solidified Sludges, and Underlying Subsurface Soils: Selection of remedies for this phase is scheduled for 1990. Cleanup will begin following completion of the engineering design of the selected Environmental Progress The soil excavations, capping, and other emergency actions performed by the EPA have greatly reduced the potential for exposure to contaminants at the American Creosote site while further investigations and the design of the soil cleanup remedies are being completed. ------- ANACONDA/MILGO FLORIDA EPA ID# FLD020536538 REGION 4 CONGRESSIONAL DIST. 17 Dade County Miami Aliases: Anaconda Aluminum Applied Technologies and Engineering Milgo Electronics Corporation Site Description The Anaconda/Milgo site is composed of two facilities located directly across the street from each other and covers 1 1/2 acres. The two facilities are Anaconda Aluminum and Milgo Electronics; the Anaconda portion of the site covers approximately 1 acre. Operations began in 1957 and consisted of an electrochemical process using acids and an aluminum-laden caustic base to produce a film of protective coating on aluminum. Raw materials used in the process included sulfuric acid, sodium hydroxide, caustic soda, detergents, and dyes. Waste anodizing sludge was pumped to a cement neutralizing pit where sulfuric acid or caustic soda was added to balance the pH levels. Air was used for mixing, and then solids were left to settle on the bottom. The clear liquid was pumped to a soakage pit for disposal to the groundwater. The sludge subsequently was disposed of at the County dump. The soakage pit had a holding capacity of 1,892 gallons and was licensed by the County. In 1979, the County required Anaconda to install a groundwater monitoring well southeast of the pit. Anaconda ceased operations in early 1983. Operations began at the Milgo portion of the site in the late 1960s and consisted of chrome, nickel, and copper electroplating of data processing equipment and the manufacturing of cabinets for electronic components. A chrome reduction treatment system discharged treated wastewater to a 360-square- foot drainfield on the premises. The system was designed to treat an average daily flow of 7,200 gallons. Samples collected from the effluent In 1973 by the County contained iron, chromium, zinc, and lead. Approximately 1,200 gallons of sludge generated yearly by the treatment system were removed by tanker truck and hauled off site. Operations at Milgo ceased in summer 1984. Both companies disposed of liquid wastes via on-site drainfields. Sampling conducted in 1987 indicated heavy metal contamination in the groundwater. The contaminated groundwater reaches the Biscayne Aquifer, the source of drinking water for approximately 750,000 residents of the Miami area. The site is located in an industrialized area northeast of Miami International Airport. Site Responsibility: The site is being addressed through a combination of Federal and State actions. NPL LISTING HISTORY Proposed Date: 11/15/89 March 1990 NPL HAZARDOUS WASTE SITES 9 continued ------- ANACONDA/MILGO IV Threats and Contaminants The groundwater contains heavy metals such as zinc, iron, selenium, chromium, and copper; cyanide; and volatile organic compounds (VOCs) from the former manufacturing and process waste disposal practices. Sediment, surface water, and soils contain heavy metals such as mercury, selenium, and arsenic. There is a potential health threat if people come into direct contact with the contaminated groundwater, soil, sediments, or surface water. However, sampling has indicated there are no immediate human health threats from this site. Cleanup Approach The site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site. Response Action Status Entire Site: The EPA conducted an initial investigation of the site in 1989 and determined that the site does not appear to pose an immediate threat to public health or the environment. However, the EPA is planning to conduct a thorough investigation to explore the nature and extent of contamination in 1992. Environmental Progress At the time this summary was written, the Anaconda/Milgo site just obtained NPL status and it was too early to discuss environmental progress. The EPA will be performing a study to assess the need for any intermediate actions required to make the site safer while waiting for cleanup actions to begin. Results of this assessment will be discussed in our next edition. 10 ------- ANODYNE, INC. FLORIDA EPA ID# FLD981014368 REGION 4 CONGRESSIONAL DIST. 17 Dade County Sunshine State Industrial Park in North Miami Beach Site Description The Anodyne, Inc. site is a building in North Miami Beach that covers less than an acre. Its two tenants currently are Mr. Furniture, a furniture manufacturer, and United Parcel Service. From the early 1960s until 1975, however, Anodyne, Inc. produced lithographs and silkscreen prints on the site. Workers reportedly disposed of wastes in an injection well near the building as early as 1960. In a 1973 inspection, Dade County discovered that the waste was also being dumped directly onto the ground. Groundwater contamination was discovered in 1986 as a result of an EPA inspection of the site. The Biscayne Aquifer, which supplies drinking water for all of Dade County, is directly beneath the site. The site is located in an industrial park. The W.A. Oeffler and Westside well fields are within 3 miles of the site; they provide drinking water to approximately 148,000 people. Site Responsibility: This site is being addressed through a combination of Federal, State, and potentially responsible parties' actions. IMPL LISTING HISTORY Proposed Date: 06/24/88 Final Date: 02/21/90 Threats and Contaminants Samples indicated elevated levels of several heavy metals from former site operations in the shallow on-site groundwater. Relatively low concentrations of volatile organic compounds (VOCs) were also detected in a groundwater sample. On-site soil samples contained elevated levels of several heavy metals and VOCs. People may be at risk by touching or accidentally ingesting contaminated soil or groundwater. Cleanup Approach The site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site. March 1990 NPL HAZARDOUS WASTE SITES 11 continued ------- ANODYNE, INC. Response Action Status Entire Site: One of the parties potentially responsible for contamination at this site will conduct a study to define the extent of contamination and to determine possible cleanup methods. An intensive investigation is scheduled to begin in 1990. This study will determine the nature and extent of soil and groundwater pollution and will recommend the best cleanup alternatives. Planning activities for the investigation began in early 1990; the investigation is slated for completion in early 1991. , Site Facts: The EPA started meeting with the parties potentially responsible for the contamination of the site in 1989 to discuss funding for the cleanup. Property Investments, one of the responsible parties, signed an Administrative Order on Consent in early 1990 to conduct a study of the nature and extent of contamination at the site. Environmental Progress After adding the Anodyne, Inc. site to the NPL, the EPA determined that the site does not currently pose an immediate threat to public health or the environment while the studies into permanent cleanup strategies are taking place. 12 ------- B & B CHEMICAL COMPANY FLORIDA EPA ID# FLD004574190 REGION 4 CONGRESSIONAL DIST. 17 Dade County Hialeah Site Description The B & B Chemical Company has manufactured industrial cleaning compounds on this, 2-acre site in Hialeah since 1958. The company prepares its products in mixing vats which, along with the company's tank trucks, are washed down once a year. Before 1976, the wash water was put into unlined lagoons. Since then, the company has run it through a treatment system before discharging it to the Hialeah sewers. Officials have been concerned about the impact of the lagoons on groundwater quality since 1975. The underlying Biscayne Aquifer supplies drinking water for all of Dade County. This site is in a highly industrialized area. Four public well fields are within 3 miles of the site and serve approximately 750,000 people. One well is within 3,000 feet of the, site. Production from the well fields has been curtailed due to groundwater contamination. The Miami Canal is 800 feet to the southwest of the" site. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 06/24/88 Threats and Contaminants In 1985, the EPA found volatile organic compounds (VOCs) including chlorobenzenes and dichloroethylene from former manufacturing operations in monitoring wells on and off the site; they also found chromium in on-site wells. Health threats include drinking polluted groundwater. Cleanup Approach This site is being addressed in an initial action and a long-term remedial phase focusing on cleanup of the entire site. March 1990 NPL HAZARDOUS WASTE SITES 13 continued ------- B & B CHEMICAL COMPANY Response Action Status Initial Action: B & B Chemical Company, under an agreement with Dade County, operated the groundwater recovery and treatment system at the site until 1989, when they unilaterally stopped recovery of the groundwater. Entire Site: More information on the extent of contamination from the site is needed before the EPA can select a cleanup remedy. The EPA is preparing a study, scheduled to start in 1990, in order to determine the nature and extent of groundwater contamination. The study is slated for completion'in 1991. The earlier groundwater treatment performed by the parties potentially responsible for site contamination and the shut-down of affected wells have greatly reduced the •'' potential for exposure to contaminants from the B&B Chemical Company site while further investigations are taking place. 14 ------- BEULAH LANDFILL FLORIDA EPA ID# FLD980494660 Site Description REGION 4 CONGRESSIONAL DIST. 01 Escambia County Pensacola The 80-acre Beulah Landfill site was operated by Escambia County from 1950 to 1984. Its north and south sections were run independently. The northern landfill, used from 1950 to 1960, accepted mostly municipal trash. The southern sludge disposal pit began receiving domestic septic tank wastes in 1968 and continued to take municipal trash, industrial waste, demolition debris, and municipal sludges until 1984, when the State ordered a halt to operations at the pit. From 1980 to 1986, the landfill operated under State order, accepting only specified wastes. Several residences within 3 miles of the landfill draw drinking water from the upper 150 feet of the local sand and gravel aquifer. The nearest well is 700 feet from the site. Eleven Mile Creek, at the downstream edge of the site, is used for recreational activities. Site Responsibility: This site is being addressed through Federal actions. NPL LISTING HISTORY Proposed Date: 06/24/88 Threats and Contaminants EPA tests showed that wastes on the site contain anthracene, naphthalene, fluoranthene, pyrene, pentachlorophenol (PCP), polychlorinated biphenyls (PCBs), and zinc. The groundwater and surface water are also contaminated with zinc. People trespassing on the site could be exposed to contaminants in the wastes on site. People ingesting contaminated groundwater may be at risk. Cleanup Approach This.site is being addressed in a single long-term remedial phase focusing on soil and groundwater cleanup at the site. March 1990 NPL HAZARDOUS WASTE SITES 15 continued ------- BEULAH LANDFILL Response Action Status Soil and Groundwater: The EPA will undertake an intensive study of soil and groundwater contamination at the site in 1990. This investigation will also recommend the best strategies for final cleanup. It is slated for completion in early 1992. Once the investigation is completed, a final selection of a remedy will be made. Site Facts: From 1980 to 1986, the landfill operated under a Consent Order with the Florida Department of Environmental Regulation (FDER) to accept only specified wastes. -, , Environmental Progress After proposing this site to the NPL, the EPA performed preliminary investigations and determined that there were no immediate actions needed at the Beulah Landfill site while investigations into cleanup strategies are taking place. 16 ------- BMI-TEXTRON FLORIDA EPA ID# FLD052172954 Site Description REGION 4 CONGRESSIONAL DIST. 12 Palm Beach County Lake Park Alias: Basic Microelectronics, Inc. From 1969 until 1986, operators of the 3 1/2-acre BMI-Textron facility made chrome- backed glass plates used in producing electronic components. Workers used cyanide to etch the glass. The facility discharged liquid wastes to percolation ponds and drain fields for four years under an industrial wastewater permit issued by the Florida Department of Environmental Regulation (FDER). Four wells at the facility monitored compliance with the terms of the permit. In 1983, operators received a Notice of Violation from the State, and subsequently reported that the site's soil and groundwater were contaminated with cyanide. Two municipal water systems draw from wells within 3 miles of the site. They serve approximately 106,000 people in Lake Park, Riviera Beach, North Palm Beach, and Palm Beach Gardens. Site Responsibility: This site is being addressed through a combination of Federal, State, and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 06/24/88 IV Threats and Contaminants The groundwater and soil are contaminated with cyanide and fluoride from former production processes. Shallow groundwater is also contaminated with barium, chromium, and nitrates. Contaminated groundwater used for a water supply source on the site poses potential threats to health or could possibly enter downgradient wells. A fence surrounding the site limits threats from exposure through direct contact or inhalation of the contaminated dust. Cleanup Approach This site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on soil and groundwater contamination. March 1990 NPL HAZARDOUS WASTE SITES 17 continued ------- BMI-TEXTRON Response Action Status Immediate Actions: Under State order, the owner removed about 680 cubic yards of cyanide-contaminated soil and transported it to an EPA- approved hazardous waste facility in 1984. In 1986, the EPA discovered cyanide and fluoride in on-site groundwater and soil. In 1986, again under State order, the owner agreed to develop a plan to clean up contaminated groundwater. The company submitted its proposal in 1987. The removal of soils from the contaminated ponds is currently taking place. Soil and Groundwater: Under EPA monitoring, the owner will undertake an intensive study of the nature and extent of soil and groundwater contamination at the site. This investigation will also recommend the best alternatives for final cleanup. It is slated to start in late 1990 and conclude in early 1993. Site Facts: In 1984, BMI and the State of Florida entered into an agreement requiring the company to remove contaminated soils at the site and to submit a detailed monitoring program for determining the nature and extent of groundwater contamination at the site. BMI agreed to comply with another State Consent Order in 1986 to develop a plan to clean up contaminated groundwater, and the company submitted a cleanup proposal in 1987. Employees notified officials in 1988 of concerns about the water safety. Environmental Progress The removal of contaminated soils has greatly reduced the potential for exposure to hazardous materials at the BMI-Textron site. These actions have protected the public health and the environment while further investigations and cleanup activities are planned. 18 ------- BROWN WO PRESERVING FLORIDA EPA ID# FLD980728935 Site Description REGION 4 CONGRESSIONAL DIST. 02 Suwannee County 2 miles west of Live Oak Aliases: Live Oak Perry South Georgia Railway/Wood Plant From 1946 until 1978, the Brown Wood Preserving site was operated as a wood- treatment facility on this 55-acre site in Live Oak. Several different companies ran the facility over its 30-year lifespan; the plant burned and was rebuilt in 1974. Operators used creosote and pentachlorophenol (PCP) in pressure treatment processes and discharged wastewater into an open ditch, where it flowed into a 5-acre unlined impoundment A 3-acre upgradient lagoon contained 3,000 cubic yards of creosote materials. The area surrounding the site is rural and light agricultural. Homes, businesses, light industry, a trailer park, a private airport, and a County storage yard are all located within 1/2 mile of the site. The trailer park houses approximately 450 residents. Sinkholes and public and private wells lie within 2 miles of the site, but the aquifer is not currently threatened, because contamination has not reached it. Site Responsibility: The site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Final Date: 09/01/83 V Threats and Contaminants Testing during cleanup studies in 1985 and 1986 showed soils in the disposal lagoon and drainage ditch to be contaminated with carcinogenic polyaromatic hydrocarbons (PAHs) from the wood-treatment processes. Sediments in the disposal lagoon and drainage ditch were also found to be contaminated with PAHs. Touching or accidentally consuming contaminated soil or dust could endanger human health. Cleanup Approach The site is being addressed in two stages: immediate actions and a long-term remedial phase directed at cleanup of the entire site. March 1990 NPL HAZARDOUS WASTE SITES 19 continued ------- BROWN WOOD PRESERVING Response Action Status Immediate Actions: Initial actions were performed at the site in 1988. Activities included: (1) treatment and discharge of approximately 200,000 gallons of lagoon and pit water; (2) demolition, salvage, and removal of facilities and process equipment on site; (3) excavation and solidification of 15,000 tons of contaminated sludges; and (4) backfilling of the retort pit. These actions reduced the levels of contaminants in the soil. The site was fenced and warning signs were posted in 1988. Entire Site: The EPA selected the following cleanup remedy for the site: (1) removing the lagoon water, treating it (if necessary) and discharging it to a sewage treatment plant; (2) excavating and treating the most severely contaminated soil and sludge and disposing of it off site; (3) breaking down contaminants in the remaining soils biologically in a 14-acre treatment area constructed with a liner and an internal drainage and spray irrigation system; (4) covering this treatment area with clean fill after it served its purpose; and (5) monitoring groundwater and the biological cleanup system for up to 5 years. The parties responsible for site contamination finished the cleanup actions outlined in the remedy to the EPA's satisfaction in 1989. In conducting the cleanup activities, workers also: (1) cleared 6 acres; (2) removed an abandoned railroad track; (3) installed a clay liner; (4) built containment berms around the perimeter; (5) installed a treatment area surface drainage network and run-on drainage swales; (6) shaped the runoff retention road; (7) placed contaminated soil in the treatment and stockpile area; and (8) installed an irrigation system. Operation and maintenance will consist of quarterly sampling of the biologically degraded soils for 2 years and groundwater sampling for 5 years. Site Facts: The Consent Decree between the EPA and the parties responsible for the contamination was entered on October 24,1988 for performance of the engineering design and actual cleanup activities as well as the operations and maintenance functions for the site. Under EPA monitoring, the parties responsible for site contamination have finished cleaning up the site. The Brown Wood Preserving site is scheduled to be deleted from the NPL in mid-1994. Environmental Progress The Brown Wood Preserving site has been cleaned up and meets all Federal and State standards. The site will be monitored for a period of 5 years to ensure that the cleanup methods are effective and continue to protect human health and the environment, at which time the site will be deleted from the NPL. 20 ------- CABOT/KOPPE FLORIDA EPA ID# FLD980709356 REGION 4 CONGRESSIONAL DIST. 10 Alachua County ' Gainesville „<. Aliases: K-Mart Site Cabot Carbon Site Description The Cabot/Koppers site covers 170 acres bridging two properties in Gainesville, near ;v* the intersection of N. 23rd Avenue and N. Main Street. Koppers, a wood-treating operation, owns the western part of the site and still operates on 82 acres of the site. Cabot Carbon formerly operated on the eastern portion of the site, on its own 49 acres, making naval stores and charcoal,from pine stumps. Koppers preserves wood utility poles and timbers using creosote and chromated copper arsenate. Pentachlorophehol (PCP) was used in the past. Koppers currently recycles its process wastes and disposes of residues in an environmentally sound manner. The contamination on the , site may be attributable to the past use of wastewater holding ponds. The old pond areas have since been filled with clean dirt and are now used as wood storage areas. During the years that Cabot Carbon operated (1945-1965), the plant generated about 6,000 gallons of crude wood oil and pitch each day. Workers discharged process wastewater containing pine tar into unlined surface impoundments. A local developer purchased the, land in 1966 and drained the contaminated ponds into a nearby wetland and into Hogtown Creek. The land was sold again in 1977 to a different developer who- began building a shopping complex. Construction workers mixed the remaining pine tar sludges from the pond areas into the topsoil and built an unlined stormwater '; retention pond over the old contamination site. Citizens soon noticed a dark-stained, foul-smelling liquid seeping into an uncovered drainage ditch along N. Main Street Gainesville's .population is 151,300, and about 2/3 of the city is drained by Hogtown Creek. Approximately 2,000 people live within a 1/2-mile radius of the site, and there are 11 schools within a 1-mile radius of the site. Site Responsibility: L\ This site is being addressed through a combination of Federal, State, and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 09/08/83 Final Date: 09/01/84 Threats and Contaminants Groundwater is contaminated with arsenic; groundwater near the land surface contains volatile organic compounds (VOCs) and creosote compounds from the former process waste disposal practices. The soil "•;' also is contaminated with creosote products; however, contaminants .*•' were below levels that would pose adverse health effects. A trailer park lies next to the contaminated ditch, and children play in that area. People coming into direct contact with contaminated groundwater may be at risk. Nearby wetlands may also be affected by contaminants from the site. March 1990 NPL HAZARDOUS WASTE SITES 21 continued ------- CABOT/KOPPERS Cleanup Approach The site is being addressed in two stages: an initial action and a long-term remedial phase focusing on cleanup of the entire site. Response Action Status X* Initial Action: The initial action provides for the collection of up to 150,000 gallons of leachate per day from the N. Main Street ditch. This water is pumped by the State from a lift station on the ditch to the Kanapha Sewage Treatment Plant for treatment. Water quality data indicate that the leachate collection and removal system has been effective in significantly removing contamination from Hogtown Creek. Entire Site: The Florida Department of Environmental Regulation (FDER) began an intensive study of soil and groundwater contamination at the site in 1984. In 1987, when the FDER ran out of funds, the EPA entered into a Consent Order with the parties potentially responsible for the site contamination to conduct an investigation of the site. This investigation will determine the nature and extent of pollution problems at the site, including an EPA-conducted risk assessment, and will recommend the best strategies for final cleanup. The study is slated for completion in late 1990. Site Facts: The FDER requested civil penalties, injunctive relief, and cost recovery in its 1983 complaint against Cabot Corporation, but the court struck all motions except cost recovery in 1984. The parties potentially responsible, Beazer Materials & Services (formerly Koppers) and Cabot Corporation, are working under a Consent Order to complete site studies of the contamination and to evaluate cleanup options. There is much public concern about the extent of contamination, public exposure, and present and future development of the site and surrounding property. Environmental Progress The leachate pumping system operated by the State has been effective in removing much of the contamination from Hogtown Creek and the N. Main Street ditch, thereby reducing the potential for exposure to hazardous materials for the surrounding population. Further studies will indicate what technologies should be used for a permanent cleanup of the Cabot/Koppers site. 22 ------- CECIL FIELD NAVAL AIR SX FLORIDA EPA ID# FLD517002244 Site Description REGION 4 CONGRESSIONAL DIST. 03 Duval County 12 miles southwest of downtown Jacksonville The Naval Air Station (MAS). Cecil Field site is divided into three areas: NAS Cecil Field (proper), the Yellow Water Weapons Department, and the Whitehouse Outlying Landing Field.- Work in support of the base mission includes fuel storage and transportation systems and intermediate,maintenance and repair of aircraft and engines. Maintenance activities over the years generated a variety of materials that were disposed of on the facility. These include: materials resulting from construction activities; municipal solid waste and municipal wastewater treatment plant sludge; and miscellaneous industrial wastes including waste oils or solvents, paints, and spilled fuels. Current disposal practices are regularly surveyed for conformance with local. State, and Federal regulations. Approximately 3,500 people live on base and 2,200 people live within a 1-mile radius of the base. Water is supplied to base residents from wells that tap the Floridian Aquifer. Off-base residents receive water from private wells that tap into the secondary artesian aquifer. The area surrounding the base contains wetlands, rivers, streams, and agricultural land. All surface water within 3 miles downstream of NAS Cecil Field waste sites are classified by the Florida Department of Environmental Regulation (FDER) as Class III waters; they are for recreational use and the propagation and management of fish and wildlife. Lake Fretwell is stocked with bass for sport fishing and a recreational complex has been developed along its northeastern shore. • • Site Responsibility: This site is being addressed through Federal actions. IMPL LISTING HISTORY Proposed Date: 07/14/89 Threats and Contaminants II On-site groundwater near seven of the sources of contamination have been found to have concentrations of heavy metals, solvents, paint wastes, and trichloroethylene (TCE) from former waste disposal practices. Solvents have been identified in surface and subsurface soils near the known sources of contamination. Sediments from Rowell Creek, which is dammed to form Lake Fretwell, contain methylene chloride and heavy metals.. Shallow groundwater is used for irrigation and firefighting. The potential exists for on-site contaminants to migrate into the groundwater in both aquifers and into off-base private wells. If contaminated groundwater should move off site, local residents could also be exposed to contaminants that have bioaccumulated in produce or aquatic life. Surface water located on the site that has shown contamination include: Yellow Water Creek and its tributaries, Caldwell Branch, Sal Taylor Creek, Rowell Creek, and Lake Fretwell. March 1990 NPL HAZARDOUS WASTE SITES 23 continued ------- CECIL FIELD NAVAL AIR STATION Cleanup Approach The site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site. Response Action Status Entire Site: The Navy has submitted a draft site cleanup plan, a Health and Safety Plan, a Sampling and Analysis Plan, a Community Relations Plan and a Site Management Plan to the EPA. Cleanup activities at the site will be divided into several stages, and the Navy will begin cleanup work after the investigation into cleanup alternatives is completed. The Navy plans to further investigate the potential sources of contamination and the migration of hazardous contaminants at 10 of the 18 areas identified in the Initial Assessment Study (IAS). During the IAS investigation, an additional area of potential contamination was discovered. Site Facts: As part of the Installation Restoration Program (IRP), a program funded by the Department of Defense (DOD) to identify, investigate, and control hazardous wastes on military installations, the Navy conducted an IAS that identified the waste disposal areas located throughout the base, including: landfills, rubble disposal areas, waste oil pits, firefighting training areas, and ammunition disposal areas. Environmental Progress After proposing the NAS Cecil Field site to the NPL, the EPA conducted studies that determined no immediate risks to public health or the environment presently exist while studies into cleanup technologies are being conducted by the Navy. 24 ------- CHEM-FORM, FLORIDA EPA ID# FLD080174402 Site Description REGION 4 CONGRESSIONAL DIST. 14 Broward County Pompano Beach Jet engine parts were manufactured at the 4-acre Chem-Form, Inc. site from 1962 to 1985. The operations included the manufacturing of a high-tech drilling machine, which involved the use of acids. In 1977, the Broward County Pollution Control Board found the company in violation of regulations for the discharge of industrial wastes onto the ground. In 1985, the EPA found the soil and groundwater contaminated with heavy metals and other contaminants. The Biscayne Aquifer is underneath the site and supplies all municipal water to Broward County. Four municipal wells are located within 3 miles of the site and serve approximately 93,000 people. Site Responsibility: This site is being addressed through Federal and potentially responsible parties'actions. IMPL LISTING HISTORY Proposed Date: 06/24/88 Final Date:- 11/11/89 L\ Threats and Contaminants The groundwater and soil are contaminated with heavy metals including chromium, nickel, and copper from former manufacturing processes. People who are exposed to contaminated groundwater or soil through drinking or touching them may be at risk. Numerous cavities in the limestone underlying the site facilitate movement of contaminants into the groundwater. Cleanup Approach This site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site. March 1990 NPL HAZARDOUS WASTE SITES 25 continued ------- CHEM-FORM, INC. Response Action Status Entire Site: The parties potentially responsible for site contamination are conducting a study to determine the type and extent of the contamination. Once the study is completed in 1991, alternatives for the cleanup will be recommended. Cleanup activities may begin sooner, as the study workplan will be reviewed for approval in 1990, and the site work may begin later the same year, starting with soil screening activities. Site Facts: In 1989, the EPA and the parties potentially responsible for the site contamination signed an Administrative Order, requiring them to conduct a study of the site. Chem-Form, Inc. is adjacent to Wilson Concepts of Florida, which is also on the NPL Environmental Progress After adding this site to the NPL, the EPA performed preliminary investigations and determined that there were no immediate actions currently needed at the Chem-Form site while further investigations continue and cleanup activities begin. 26 ------- CITY INDUS FLORIDA EPA ID# FLD055945653 Site Description REGION 4 CONGRESSIONAL DIST. 05 Orange County Winter Park Alias: City Chemical The City Industries site operated from 1971 to 1983 on a 1-acre parcel of land and was involved in the receipt, handling, storage, reclamation, and disposal of a wide variety of waste chemicals including solvents, paint/varnish wastes, plating wastes, polychlorinated biphenyls (RGBs), and inks. The company abandoned the site in 1983, informing the State that it lacked the resources to continue operations and leaving approximately 1,200 drums and 12,000 gallons of unknown liquids and sludges in large tanks. Volatile organic compounds (VOCs) were found in the shallow aquifer beneath the site. Approximately 120,000 people live within 3 miles of the site. The nearest residence is 1 mile away. Within 3 miles of the site are schools, nursing homes, and hospitals. Municipal wells are located 1/4 mile upgradientoi the site in the deeper Floridian aquifer. Site Responsibility: This site is being addressed through Federal and State actions. NPL LISTING HISTORY Proposed Date: 10/01/84 Final Date: 10/04/89 Threats and Contaminants The groundwater and surface water are contaminated with VOCs from former waste disposal practices. The soils are contaminated with VOCs, phthalates, and various heavy metals. People who touch or drink contaminated surface water or groundwater may be at risk. The shallow aquifer beneath the site is contaminated and the contaminant plume may potentially migrate to the Floridian aquifer. The risk posed by the contaminated soil has been reduced to an acceptable range as a result of soil removal activity. Cleanup Approach The site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of the entire site. March 1990 NPL HAZARDOUS WASTE SITES 27 continued ------- CITY INDUSTRIES Response Action Status I"""" Immediate Actions: In 1983, the State crushed and removed 41 tons of. drums and disposed of 65 truck and tanker loads of contaminants at an EPA-approved facility. In 1984, the EPA emptied, cut open, and cleaned the holding tanks. Approximately 1,700 tons of contaminated soil were incinerated to remove the contaminants. The treated soil remains on the site. Entire Site: The remedy chosen by the EPA to clean up the site includes extracting the groundwater and then air stripping and discharging it to a local Publicly Owned Treatment Works (POTW). If the POTW does not agree to accept the discharge, the EPA will implement its contingency alternative, which includes treating the extracted groundwater by aeration, filtration, precipitation, and carbon adsorption followed by surface water discharge. Site Facts: In 1984, the EPA issued an Administrative Orderto City Industries requiring cleanup of the site; the company ignored the order. Also in 1984, the State filed a civil complaint against the land owner, operator, and four companies associated with the operator. The EPA is about to begin negotiations with the parties potentially responsible for the contamination of the site to develop the technical specifications and engineering design for cleaning up the site. Environmental Progress The removal of solid waste and treatment of soil have greatly reduced the potential for exposure to hazardous materials at the City Industries site. This has helped protect the public health and the environment while further investigations and cleanup activities take place. 28 ------- COLEMAN-EVANS WOOD PRESERVING FLORIDA EPA ID# FLD991279894 Site Description REGION 4 CONGRESSIONAL DIST. 03 Duval County Whltehouse, 8 miles west of Jacksonville The Coleman-Evans Wood Preserving Company site is an active wood preserving facility located in a residential and light industrial area of Whitehouse. The site covers 11 acres and consists of two distinct areas: the western portion, which contains a wood treating facility, and the eastern portion, which consists of a landfill and has been used to dispose of wood chips and other wastes. Since 1954, Coleman-Evans produced wood products that contain pentachlorophenol (PCP). Wastes from this process were discharged into an on-site drainage ditch and into two unlined sludge disposal pits. Contamination was discovered in the groundwater in the area in 1980. As a result, the facility constructed a treatment system to clean the groundwater. Approximately 1,000 people reside within a 1-mile radius of the site. This heavily populated residential area is not connected to a municipal water supply; therefore, the area residents depend on private wells for their drinking water. There are approximately 180 wells within a 1-mile radius of the site. Site Responsibility: This site is being addressed through a combination of Federal, State, and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Threats and Contaminants Shallow groundwater in the residential area adjacent to the site is contaminated with PCP, volatile organic compounds (VOCs) including phenol and toluene, and heavy metals including chromium and lead from former process wastes. Sediments are contaminated with PCP, and the soil is contaminated with heavy metals, PCP, oil, and grease. Area residents are at risk if direct contact is made with contaminated soil or if contaminated groundwater from the shallow aquifer is accidentally ingested. Risks from groundwater have been reduced by provision of alternative water to residents whose water supply was contaminated. March 1990 NPL HAZARDOUS WASTE SITES 29 continued ------- COLEMAN-EVANS WOOD PRESERVING CO. Cleanup Approach The site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of the entire site. Response Action Status Immediate Actions: In 1985, the EPA provided the residents whose water was contaminated with an alternate source of water. The soils in the on- site waste pits were sampled, excavated, and disposed. The water and oil that have been filtering into the excavated pits were sampled and treated, and the pit was backfilled to the original grade with clean fill dirt. . . .' Entire Site: The soils and sediments in which the PCP levels exceed human health standards will be removed and incinerated on site by the EPA. The soil that is not contaminated with PCP will be backfilled on site. Groundwater recovery will be treated by dewatering to ease removal and to treat groundwater with high concentrations of PCP. Recovered groundwater will be stored and analyzed. If the PCP levels exceed the determined amount, groundwater will be treated on site by carbon adsorption before being discharged to the surface water by way of the drainage ditch. After the EPA's treatability studies were completed, it was decided that solidification and bioremediation would be considered as remedies for soil and sediment cleanup. Design of these technologies is scheduled to begin in 1990. Site Facts: On October 15, 1984, the State of Florida issued an Administrative Consent Order to Coleman-Evans Wood Co. to clean up the site. In 1980, complaints of taste and odor problems in nearby private water wells led to investigations by state and local officials. Environmental Progress The provision of a safe drinking water supply and the removal of contaminated soils have reduced the potential for exposure to contaminated materials at the Coleman- Evans Wood Preservation Co. site while permanent cleanup activities are being conducted. 30 ------- DAVIE LANDK FLORIDA EPA ID# FLD980602288 Site Description REGION 4 CONGRESSIONAL DIST. 16 Broward County 10 miles southwest of Fort Lauderdale Alias: Broward County Solid Waste Disposal Facility The Davie Landfill site consists of an 80-acre trash landfill, a 30-acre sanitary landfill and an 8-acre sludge lagoon, near the intersection of Orange Drive and Boy Scout Road. The facility began operation in 1964, accepting trash and ash from the County's adjacent garbage incinerator, and ceased landfilling activities in 1987 when the facility reached its design capacity. The solid waste landfill was used to dispose of the municipal solid waste being incinerated at the on-site incinerator. Construction debris, tires, and other wastes that could not be incinerated were also placed in the solid waste landfill. The sludge lagoon was.constructed in 1971 in an unltned natural depression on site to accept grease trap pump-outs and septic tank and treated municipal sludges. The lagoon has overflowed on several occasions, resulting in surface water discharges to an adjacent borrow pit. The sludge lagoon was closed in 1981. The incinerator was closed in 1975 because the excessive paniculate emissions, failed to meet new air regulations. The sanitary landfill was opened to replace the closed incinerator. Dairy farms, ranches, and horse stables are located in the vicinity of the site. Approximately 50 homes are located south of the site; the nearest residence is 1/2 mile away. All municipal water supplies in the area receive water drawn from the Biscayne Aquifer. The aquifer is the sole source of potable water for about 10 000 residents in the area. Site Responsibility: This site is being addressed through a combination of Federal, State, and County actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/08/83 Threats and Contaminants The groundwater and the water in the borrow pits on site and downgmdient of the site show elevated levels of sulfate, chloride, lead, and ammonia. Benzene, vinyl chloride, and other compounds have been detected in monitoring wells and private wells south of the landfill. Sludge from the lagoon was found to contain cyanide.and sulfides. Potential health threats include accidental ingestion, inhalation, and direct contact with contaminated soil, groundwater, surface water, and sediments. The site is fenced, and access to the site is restricted. March 1990 NPL HAZARDOUS WASTE SITES 31 continued ------- DAVIE LANDFILL Cleanup Approach The site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site. Response Action Status Entire Site: The State required the County to provide service connections to the municipal water supply system for each affected residence near the site. The County offered residents bottled water until the water lines were functional. The alternate water supply is now in place. Cleanup technologies chosen to address sludge lagoon contamination include dewatering and stabilization of the sludge lagoon contents, placement of treated sludge lagoon contents in a lined sanitary landfill cell, and installation of an approved cover on the cell. The County initiated site construction on the sludge lagoon in 1989, and cleanup activities are completed. Studies are continuing to determine whether the actions taken were sufficient to clean up the groundwater. Site^Facts: Area residents have been concerned about drinking water because the water quality is poor in the area. The raw water is discolored and has high levels of hydrogen sulfide and iron. Environmental Progress The provision of an alternate water supply and completion of the cleanup activities have reduced the danger of exposure to contamination while the County and the EPA are conducting further studies into the effectiveness of the cleanup technologies at the Davie Landfill site. 32 ------- DUBOSE OIL PRODUCTS COMPANY FLORIDA EPA ID# FLD000833368 Site Description REGION 4 CONGRESSIONAL DIST. 01 Escambia County Cantonment, 10 miles north of Pensacola The 20-acre Dubose Oil Products site consists of a process facility and three bermed ponds. The site was an oil recovery facility that operated from 1979 through 1981. Waste materials handled on the site included waste oils, petroleum refining waste, wood treatment process waste, spent solvents, spent "pickle liquors," and various paint wastes. These materials initially came to the site in bulk tanker trailers and drums. and then were stored in a treatment tank prior to processing. Spent solvent and process wastes from petroleum refining and wood treatment operations were transported to the facility in 55-gallon drums. Analysis of samples taken from the site, indicate the presence of numerous volatile organic compounds (VOCs). The site ceased operations in 1982. Dubose sold some drums and crushed, stacked, and then buried a number of these drums on the site. This is a rural residential area with some agricultural and forest land nearby. Approximately 2,400 people live within 3 miles. The nearest residents live adjacent to the site. A low-lying area that forms the *-• headwaters of Jack Branch, a tributary of the Perdido River, is located along the northern edge of the site. Site Responsibility: This site is being addressed through Federal and potentially responsible parties'actions. NPL LISTING HISTORY Proposed Date: 10/01/84 Final Date: 06/01/86 Threats and Contaminants The groundwater and soils are contaminated with low levels of VOCs and heavy metals including manganese, iron, and aluminum from former process wastes. Iron naturally occurs in the water in the area. Residents . in the immediate area are provided with city water supplies, which are not threatened by contaminated groundwater. However, in the future, groundwater contaminants could migrateto a nearby sand and gravel agu/ferthat is the source of drinking water in the area. Cleanup Approach This site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of the entire site. March 1990 NPL HAZARDOUS WASTE SITES 33 continued ------- DUBOSE OIL PRODUCTS COMPANY Response Action Status IX* Immediate Actions: In 1984 and 1985, the Florida Department of Environmental Regulation (FDER) excavated 40,000 cubic yards of „ contaminated soil and placed it in a lined vault on site to prevent further contamination of the groundwater. Contaminated leachate from the vault is being treated and discharged into the North Pond. Entire Site: The parties potentially responsible for the site contamination formed a steering committee to jointly perform a study determining the type and extent of contamination at the site and to define the alternative , technologies available for cleanup. In 1990, the EPA selected final remedies for site cleanup and has initiated negotiations for the engineering design of the cleanup remedy and the actual cleanup activities. Site Facts: The State and the parties potentially responsible for site contamination have signed a Consent Order whereby these parties will perform the initial studies to determine the extent of site contamination and the alternative technologies for cleaning up the site. The public is concerned that the dam holding the North Pond, which is not well built, will break and that the pond will subsequently flood the downstream areas. Environmental Progress Provision of an alternate water supply and the containment of soil have greatly reduced the potential for exposure to contaminants and the further spread of these contaminants at the Dubose Oil Products Company site while further cleanup activities are planned. 34 ------- FLORIDA STEEL CORPORATION FLORIDA EPA ID# FLD050432251 REGION 4 CONGRESSIONAL DIST. 12 Martin County 2 miles northwest of Indiantown Site Description The 150-acre Florida Steel Corporation site is a former steel mill that operated from 1970 to 1982, when it closed for economic reasons. During its operation, casting and rolling were performed at extremely high temperatures. Subsequently, equipment and motors were cooled by water, which picked up iron oxide and small particles from the hot steel and collected excess lubricating oils and hydraulic fluid. The cooling water was captured by concrete drains and sumps and then piped to a Concrete Recirculating Reservoir (CRR) where the iron oxide particles and dense oils settled out. The floating oil that resulted from this process was subsequently removed by an oil skimmer. In addition to the steel products, three types of by-products were associated with the Indiantown Mill: (1) mill scale, the oxidized iron that separated from the hot steel as it was cooled with water sprays, (2) slag, low grade ore formed when lime was introduced as a flux into the furnace to remove impurities, and (3) Emission Control (EC) dust, the fine particles generated as the high temperatures of the electric arc furnace drove off and oxidized some of the iron and most of the other volatile metals contained in the scrap. Some of the EC dust was spread over the facility's roads, and 75,000 cubic yards were deposited on the southern portion of the site in waste piles. Florida Steel began to collect EC dust in three baghouses and transported it to a chemical plant in South Carolina for recovery of lead and zinc in 1980. The site was placed on the NPL in 1982 when the EPA found high levels of arsenic, cadmium, and lead in the EC dust and groundwater. In addition, polychlorinated biphenyls (PCBs) were found at various locations on the site. Approximately 4,800 people live within a 2-mile radius of the site. The Indiantown public water supply comes from a group of shallow wells located within 3 miles of the site. Swamp and unimproved land owned by the Seaboard Coast Line Railroad adjoins three sides of the property. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Final Date: 12/01/82 March 1990 NPL HAZARDOUS WASTE SITES 35 continued ------- FLORIDA STEEL CORPORATION T\ Threats and Contaminants Heavy metals including arsenic, cadmium, and lead from former plant processes exist in the on-site EC dust that has become airborne. The groundwater is contaminated with sodium chloride; heavy metals including lead, cadmium, and iron; and radioactive materials including radium and barium. On-site surface soils and solid wastes located in the CRR are contaminated by PCBs. Area residents could be exposed to contaminants in their drinking water. Other potential health threats include inhaling and coming into direct contact with airborne EC dust. The potential exists for contaminants in the groundwater to move into surface water that is used for irrigation, making it possible for residents to be exposed to contaminants found in locally grown crops. Swamps located adjacent to the site are threatened by contamination migrating from the site. . Cleanup Approach — '- This site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of the entire site. Response Action Status X" Immediate Actions: The EPA removed an area of on-site soil containing EC dust that was contaminated with PCBs in 1985. The PCB-contaminated soils were treated by incineration on site. Entire Site: In 1987, the parties potentially responsible for site contamination began an investigation to determine the best ways to clean up the site. This investigation is still under way. An interim report was received by the EPA for review. The potentially responsible parties also conducted additional groundwater sampling in 1990. The EPA is currently waiting for the analytical results of these additional tests. Site Facts: Negotiations with the parties potentially responsible for site contamination were concluded in 1987. As a result, these parties initiated an investigation to characterize site contamination. Environmental Progress The removal and treatment of soil has greatly reduced the potential for exposure to hazardous materials and has controlled the migration of contaminants from the site while further investigations and cleanup activities take place at the Florida Steel Company. 36 ------- GOLD COAST CORPORATION FLORIDA EPA ID# FLD071307680 REGIOIV 4 CONGRESSIONAL DIST. 16 Dade County Miami Site Description Gold Coast Oil Corporation operated a solvent reclaiming facility and bulk storage area on a 2-acre site leased from the Seaboard Coast Line Railroad from 1971 to 1982. Wastes generated by the recovery process were sprayed directly on the ground or stored in drums on site. In 1982, Seaboard removed approximately 2,500 drums, 5 tanker loads of liquid waste from bulk storage tanks, and 40 loads of contaminated soil from the site to an approved facility. The groundwater is contaminated and is part of the Biscayne Aquifer, the principal drinking water source for this part of Florida. The area surrounding the facility is primarily industrial. The majority of the residents within a 3-mile radius of the site are served by two public water supply wells fields that are not affected by the contamination at the site. The site currently is inactive and is fenced with a locking gate. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Threats and Contaminants The groundwater is contaminated with volatile organic compounds (VOCs) including methylene chloride from the former solvent recovery activities. The soil is contaminated with VOCs, as well as lead. Trespassers who accidentally touch or ingest contaminated groundwater or soil on the site may be at risk. The residents in the area obtain drinking water from municipal wells not affected by this site; however, the groundwater plume may migrate to these wells. This site is one of many contributors, to the overall contamination of the Biscayne Aquifer. A treatment system has been installed at the public water supply plants to remove heavy metals and VOCs before water enters the distribution system. March 1990 NPL HAZARDOUS WASTE SITES 37 continued ------- GOLD COAST OIL CORPORATION Cleanup Approach The site is being addressed in two stages: an initial action and a long-term remedial phase directed at cleanup of the entire site. Response Action Status Initial Action: Early actions, undertaken by Seaboard in 1982, have removed contaminated materials and soils from the site. Entire site: In 1987, the EPA selected a remedy to clean up the site that included excavating and removing soil and sludges to a federally approved facility; recovering the contaminated groundwater and treating it before discharging it; and removing and disposing of storage tanks and various structures and debris on the site. A system for treating the contaminated groundwater is currently being installed. All cleanup activities are expected to be completed in 1993. Site Facts: In 1982, Seaboard Coast Line Railroad evicted Gold Coast Oil from the property and volunteered to clean up the site. Environmental Progress By removing contaminated soil and other materials and installing a groundwater treatment system, the EPA and the parties potentially responsible for the site contamination have made substantial progress toward final cleanup of the Gold Coast Oil Corporation site. Ongoing soil and sludge cleanup, as well as groundwater treatment, continue to reduce contamination levels at the site. 38 ------- HARRIS CORPORATION/ PALM BAY FLORIDA EPA ID# FLD000602334 REGION 4 CONGRESSIONAL DIST. 11 Brevard County Palm Bay Aliases: Harris Semiconductor Harris Building 10O Site Description The Harris Corporation site covers 345 acres, and General Development Utilities, Inc. (GDU) occupies part of the site. Harris manufactures a wide variety of electronic devices and components, while GDU provides drinking water and manages the wastewater collection, treatment, and disposal system for much of Palm Bay. GDU's well field consists of 25 producing wells and is located adjacent to and downgradient from the Harris facility. The EPA found the wells to be contaminated, although the precise origin and cause of the contamination is not known. GDU provides approximately 33,000 residents of Palm Bay with drinking water. Approximately 27,500 people live within 3 miles of the site. Also included within the 3-mile radius are schools, nursing homes, hospitals, and a park. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 04/01/85 Final Date: 07/01/87 Threats and Contaminants The groundwater is contaminated with various volatile organic compounds (VOCs) and heayy metals including chromium and lead from former process waste disposal practices. People who are exposed to the contaminated groundwater may be at risk. Cleanup Approach This site is being addressed in three stages: immediate actions and two long-term remedial phases focusing on groundwater treatment and surface water and sediments treatment. March 1990 NPL HAZARDOUS WASTE SITES 39 continued ------- HARRIS CORPORATION/PALM BAY FACILITY Response Action Status Immediate Actions: One well at GDU has been taken out of service. Harris operates an extraction/treatment system, with the effluent used as process water. This process water is treated and then injected into a deep well. Harris also paid for an air stripper at GDU for the treatment of water from seven production wells. Groundwater Treatment: The remedy preferred by the EPA to clean the groundwater includes pumping the water and removing contaminants by air stripping. The contaminants removed are further treated before being released into the atmosphere. The EPA's final decision is expected in 1990. Harris installed a groundwater system in 1985. According to tests conducted in 1988, groundwater contamination has already been reduced, and this treatment is expected to continue until 1992. Surface Water and Sediments Treatment: The EPA will monitor a study of the type and extent of surface water and sediment contamination. Once the study is finished in 1992, alternatives for cleanup will be recommended. Site Facts: In 1983, the State and Harris Corporation signed a Consent Agreement for Harris to develop a groundwater restoration system. Environmental Progress The groundwater treatment facility continues to reduce the potential for exposure to hazardous substances at the Harris Corporation/Palm Bay Facility and is protecting the public water supply while further investigations take place. 40 ------- HIPPS ROAD LANDFILL FLORIDA EPA ID# FLD980709802 REGION 4 CONGRESSIONAL DIST. 03 Duval County Jacksonville Heights Site Description The Hipps Road Landfill site covers 14 1/2 acres in what was once a cypress swamp. The site area includes the landfill and an adjacent pond. During the 1960s, the facility accepted municipal and industrial wastes. The landfill ceased operations in 1970, was covered with a layer of soil, and was sold in residential lots. Concerns were first reported in the early 1970s, when a pond adjacent to the landfill developed a thick, smelly film, and fish and nearby vegetation died. The area residents depended exclusively on private wells for water until tests in 1983 showed contamination. Residents were given bottled water until the City extended the municipal water system. A residential area of about 150 homes surrounds the site. The landfill is situated above the floodplain. Surface water is used for swimming, boating, and fishing. Site Responsibility: This site is being addressed through a combination of Federal, State, and potentially responsible parties' actions. ISIPL LISTING HISTORY Proposed Date: 09/08/83 Final Date: 09/01/84 Threats and Contaminants The groundwater is contaminated with volatile organic compounds (VOCs) including vinyl chloride and benzene, as well as heavy metals including lead from former waste disposal practices. Cleanup Approach This site is being addressed in two stages: an immediate action and a long-term remedial phase focusing on cleanup of the entire site. March 1990 NPL HAZARDOUS WASTE SITES 41 continued ------- HIPPS ROAD LANDFILL Response Action Status Immediate Action: In 1985, the EPA connected residences in the area to the municipal water line. Entire Site: In 1986, the EPA selected a remedy to clean up the site, which includes recovering the groundwater and treating it at the local public works treatment plant and properly closing the landfill. A second aspect of the site cleanup plan, the landfill cover system, was completed by Waste Control, Inc. in 1989. An inspection of the cover system will take place in 1990. Waste Control, Inc., the party potentially responsible for site contamination, is also preparing the technical specifications and design for groundwater cleanup. Once the design phase is completed in 1990, the cleanup will begin. The groundwater recovery system design is anticipated to be completed in 1990. Monitoring activities to ensure that the remedies have effectively cleaned the site are scheduled to continue for 20 years using funds provided by the State of Florida. Site Facts: In 1989, Waste Control, Inc. and the EPA entered into a Consent Decree. Waste Control, Inc. agreed to design the landfill cover system and the groundwater recovery system; they have completed the landfill closure. The EPA will construct and implement the groundwater recovery system and will monitor the effectiveness of the landfill cover system. Environmental Progress By providing an alternate water supply to nearby residents and covering the landfill, the EPA and the potentially responsible party have eliminated immediate hazards at the Hipps Road Landfill site while further investigations and cleanup activities continue. The completed landfill cover has also reduced the potential for exposure to hazardous materials and prevented the further spread of contaminants to the groundwater. 42 ------- HOLLINGSWORTH SOLDERLESS TERMINAL CO. FLORIDA EPA ID# FLD004119681 Site Description REGION 4 CONGRESSIONAL DIST. 15 Broward County Fort Lauderdale The Holiingsworth Solderless Terminal Co. site is located on 3 1/2 acres in an industrial and residential area of Ft. Lauderdale. The plant was in operation from 1968 to 1982 as a solderless terminal manufacturing facility. The manufacturing process included using molten salt baths, decreasing parts, and electroplating. The wash and process waters, which contained varying concentrations of trichloroethylene (TCE) and heavy metals, were disposed of in on-site drainfields, by surface discharges, and in a 100-foot-deep injection well. In addition, wastes periodically entered the ground through spillage or other smaller drainfields. Several communities in the vicinity of the site draw water from the shallow Biscayne Aquifer. The nearest residential area is located approximately 200 feet southeast of the site. site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Threats and Contaminants Volatile organic compounds (VOCs), including vinyl chloride from former process wastes, have been detected in some of the monitoring wells on the site. VOCs and heavy metals including copper and tin have been detected in the soil. Potential health risks may exist for individuals who consume, make direct skin contact with, or inhale VOCs from the contaminated groundwater or soil. Cleanup Approach The site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of the entire site. March 1990 NPL HAZARDOUS WASTE SITES 43 continued ------- HOLLINGSWORTH SOLDERLESS TERMINAL CO. Response Action Status Immediate Actions: In 1982, Hollingsworth took several steps to determine the extent of contamination at the site. The company pumped the injection well, installed 16 on-site monitoring wells, sampled soil, conducted a groundwater gradient study, and sampled public wells. In 1987, the EPA excavated the old drainfields, exposed contaminated soil to air to allow contaminants to evaporate, and replaced the cleaned soil in the drainfields. Entire Site: The approved cleanup plan for the site includes: excavation, aeration, and on-site replacement of VOC-contaminated soils; and recovery of contaminated groundwater from the sand zones of the aquifer, with treatment and reinjection into the aquifer. Final negotiations for the cleanup work are under way. " Site Facts: Cost recovery negotiations with the parties potentially responsible for the site contamination are under way. Environmental Progress The pumping of the well and evaporation of contaminants have reduced the potential for exposure to hazardous materials at the facility or through the public water supply while the planned cleanup activities are being negotiated. 44 ------- HOMESTEAD FORCE BASE FLORIDA EPA ID# FL7570024037 Site Description REGION 4 CONGRESSIONAL DIST. 19 Bade County 25 miles southwest of Miami The Homestead Air Force Base (AFB) site lies approximately 2 miles westof Biscayne Bay. The surrounding area is semi-rural, and most of the base borders on agricultural land. Work to support the base mission includes fuel storage (JP-4, gasoline, diesel, heating oil), transportation systems, and various maintenance shops. These activities have resulted in waste materials being discharged into the environment, including petroleum hydrocarbon fuels, solvents, pesticides, and heavy metals. Current disposal practices are regularly surveyed for conformance with local. State, and Federal regulations. The base is surrounded by a canal that discharges into Military Canal and, ultimately, into Biscayne Bay. An estimated 1,600 people obtain drinking water from the Biscayne Aquifer and 18,000 acres of farmland within 3 miles of the site are irrigated from wells. The aquifer, which underlies the site, is the sole source of potable water in the area. site Responsibility: This site is being addressed through Federal actions. NPL LISTING HISTORY Proposed Date: 07/14/89 Threats and Contaminants The groundwater is contaminated with petroleum from former disposal practices. The canals surrounding Homestead AFB are probably hyraulically connected with the aquifer, and contaminants have discharged into surface waters. Potential health risks may exist for individuals who come in direct contact with or drink contaminated groundwater. Cleanup Approach This site is being addressed in a single long-term remedial phase focusing on cleanup at the entire site. March 1990 NPL HAZARDOUS WASTE SITES 45 continued ------- HOMESTEAD AIR FORCE BASE Response Action Status Entire Site: The Air Force has been conducting various studies at the site, and actions are currently proceeding at one petroleum site. A thorough study of the entire site is scheduled to be conducted in 1990 to determine the extent of contamination on site and to identify alternative technologies for the cleanup. Site Facts: Homestead AFB is participating in the Installation Restoration Program (IRP). Under this program, established in 1978, the Department of Defense (DOD) seeks to identify, investigate, and to clean up contamination from hazardous materials at various military and DOD installations. Environmental Progress After proposing this site to the NPL, the EPA and the U.S. Air Force performed preliminary site investigations and determined that there were no immediate actions currently necessary at the Homestead Air Force Base while further investigations,and cleanup activities take place. A 46 ------- JACKSONVILLE? NAVAL AIR STATJ FLORIDA EPAID# FL6170024412 Site Description REGION 4 CONGRESSIONAL DIST. 03 Duval County 9 miles south of Jacksonville The Jacksonville Naval Air Station (MAS) site is approximately 9 miles south of downtown Jacksonville. The mission of MAS Jacksonville is to, provide facilities, services, and managerial support for the operation and maintenance of naval weapons and aircraft as designated by the Chief of Naval Operations. Work in support of the base mission includes fuel storage for the transportation systems and the overhaul, intermediate maintenance, and repair of aircraft and engines. Maintenance activities at NAS Jacksonville over the years generated a variety of materials, some of which were disposed of in a landfill on the base. These materials include wastes resulting from construction activities; municipal solid waste and municipal wastewater treatment plant sludge; and miscellaneous industrial wastes, including waste oils or solvents, paints, radium paint waste, wastewaters containing heavy metals, and spilled fuels. Current disposal practices are regulated for conformance with local, State, and Federal regulations. Three aquifers underlie the NAS Jacksonville Site: the Surficial, the Intermediate, and the Floridian. Drinking water is supplied to the base via wells that tap the Floridian Aquifer. Off-base residents use the Intermediate aquifer as a drinking water source. Approximately 300 people draw drinking water from private wells in shallow groundwater within 3 miles of the Naval Air Station. Site Responsibility: This site is being addressed through Federal actions. NPL LISTING HISTORY Proposed Date: 07/14/89 Final Date: 11/21/89 March 1990 NPL HAZARDOUS WASTE SITES 47 continued ------- JACKSONVILLE NAVAL AIR STATION Threats and Contaminants The Navy found volatile organic compounds (VOCs), polychlorinated biphenyls (PCBs), and heavy metals including cadmium, chromium; and- lead in soils and the shallow groundwater near the potential sources of contamination. The Navy also found lead, chromium, and cadmium in the St. Johns River. There is no potential for direct contact with contaminants because on-base housing is located adjacent to a capped landfill. Several creeks and two small lakes are on the site. The St. Johns River is classified by the Florida Department of Environmental Regulation as Class III waters; it is used for recreation, and the propagation and management of fish and wildlife. The St. Johns River has a potential for contamination from glass beads used in aircraft paint stripping that were disposed of in the river. The station encompasses freshwater wetlands and critical habitats for the Florida manatee and the bald eagle, both designated as endangered species by the U.S. Fish and Wildlife Service. Cleanup Approach The site is being addressed in a single long-term remedial phase directed at cleanup of the entire site. Response Action Status Entire Site: The Navy had taken interim measures to control oil and solvents runoff from the old main dump into the St. Johns River; however, the system is no longer operating. The Navy plans further investigations of releases of hazardous substances and their migration and is currently preparing a work plan to investigate potential sources of contamination. These investigations will reveal the nature and extent of the contamination problems at the station and will recommend the best strategies for final cleanup. Site Facts: The Jacksonville Naval Air Station site is being addressed through a Federal Facility Agreement and the Installation Restoration Program (IRP), a specially funded program under the Department of Defense (DOD). The program is designed to identify, evaluate, and control hazardous wastes on military or other DOD installations. Environmental Progress After adding the Jacksonville NAS site to the NPL, the EPA evaluated conditions authe site and determined that the contaminated areas do not present an immediate threat to human health or the environment while investigations into a permanent remedy are being conducted. 48 ------- KASSOUF-KIMM BATTERY DIS FLORIDA EPA ID# FLD980727820 Site Description REGION 4 CONGRESSIONAL DIST. 07 Hillsborough County Tampa Aliases: Timberlake Battery Disposal 58th Street Landfill The Kassouf-Kimmerling Battery Disposal site includes a 1-acre landfill and a 4-acre wetland located in Tampa. Before 1978, this site was mined for peat, but in 1978, excavations in the marsh were filled 6 to 1-2 feet deep with lead battery casings and fill dirt that is now covered with a layer of soil. The site is bounded on the east and west by freshwater marshland. Water flows from the western to the eastern marsh via a canal across the landfill; a large lake lies to the north. The immediate area of the landfill is uninhabited and is bordered on three sides by dense plant growth. Approximately 1,500 wells are located within a 3-mile radius, although sampling has detected no well contamination off the site. The population of the surrounding neighborhood is about 5,500. The area to the south of the site is commercial and residential, with several churches, a school, restaurants, offices, and a currently inactive fish farm nearby. Site Responsibility: This site is being addressed through a combination of Federal, State, and potentially responsible parties' actions. IMPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 — Threats and Contaminants— Groundwater, soil, and surface water on the site are contaminated with heavy metals including lead, cadmium, and arsenic from former waste disposal activities. Off-site contamination is restricted to some lead in surface water and sediments. People exposed to site contaminants over a long period of time could face health threats. The site is incompletely fenced, and trespassing is evident. Cleanup Approach — — — The site is being addressed in two long-term remedial phases focusing on source control and cleanup of the marsh area. March 1990 NPL HAZARDOUS WASTE SITES 49 continued ------- KASSOUF-KIMMERLENG BATTERY DISPOSAL Response Action Status Source Control: The EPA selected a remedy for source control at this site in 1989, which includes: (1) excavating the landfill wastes and contaminated underlying soils; (2) solidifying them and applying chemical fixation; (3) disposing of them on site in the landfill area. The EPA and the State plan to have a remedial design completed by mid-1990. Marsh: The EPA arrived at a decision for cleanup of the contaminated marsh in the spring of 1990. The EPA plans to remove the marsh sediment within 20 feet of the battery landfill to a depth of 2 feet below the sediment surface and to remove the sediments from the canal east of the site extending 150 feet from the battery landfill to a depth of 2 feet. Approximately 1,500 cubic yards of contaminated sediments will be excavated from the marsh. The excavated sediments will be treated using a solidification and stabilization technology and will be placed with the solidified landfill materials. The remainder of the marsh sediments will remain on site because removing the contaminated material may cause contaminants to migrate. Site Facts: In 1983, the EPA issued an order requiring the potentially responsible parties to monitor the groundwater and surface water, perform analysis of the battery fill material, and general soil sampling. The monitoring was conducted by the parties potentially responsible for the site contamination. Currently, the EPA is negotiating with the potentially responsible parties to complete the engineering design and activities for the contamination source cleanup. Environmental Progress After preliminary investigations, the EPA determined that the Kassouf-Kimmerling Battery Disposal site does not currently pose an immediate threat to public health or the environment while studies are being conducted and the final cleanup activities are started. 50 ------- MADISON COUN3P SANITARY LANDEH3? FLORIDA EPA ID# FLD981019235 REGION 4 CONGRESSIONAL DIST. 02 Madison County Northeast of Madison Site Description The Madison County Landfill is a 133-acre site northeast of Madison that was owned and operated by the City of Madison from 1971 until 1980. During that time, ITT Thompson Industries, Inc. disposed of drums and waste containing trichloroethylene (TCE) and other compounds. The County bought the landfill in 1980 and has been operating it since then. The landfill is licensed by the State to accept municipal solid waste. In 1984, the County found TCE in monitoring wells on the site and in private wells nearby. An estimated 95 private wells and 3 city wells are within 3 miles of the site. Contamination of these wells threatens the drinking water supply of 4,400 people. site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 06/24/88 Threats and Contaminants Volatile organic compounds (VOCs), including TCE from former waste disposal practices, were detected in on-site monitoring wells and private wells near the site. Similar contaminants have been identified in the soils surrounding the landfill area. Drinking contaminated groundwater poses a health risk to those using nearby wells. Cleanup Approach The site is being addressed in two stages: initial actions and a long-term remedial phase focusing on cleanup of the entire site. March 1990 NPL HAZARDOUS WASTE SITES 51 continued ------- MADISON COUNTY SANITARY LANDFILL Response Action Status Initial Actions: The Florida Department of Environmental Regulation (FDER) removed a number of drums from one location where ITT Thompson's drums had been buried. Drums were removed from a second area in 1985. All materials were transported to an EPA-approved hazardous waste facility. When private wells were found to be contaminated, the County, and later ITT Thompson, provided bottled water and ice to affected families. In addition, the City, County, and ITT Thompson installed water filtering systems at these homes. Entire Site: In mid-1990, under EPA guidance, the parties potentially responsible for the site contamination will undertake an extensive study of the site's pollution problems. This investigation will analyze the nature and extent of groundwater and soil contamination and will suggest the best alternatives for final cleanup. It is scheduled for completion in early 1992. Site Facts: In February 1986, the FDER entered into a Consent Agreement with the City, County, and ITT Thompson requiring them to investigate groundwater contamination near the site. Environmental Progress The drum removal and the provision of an alternate drinking water supply have reduced the potential for exposure to contaminated substances at the Madison County Landfill site or through contaminated groundwater while investigations into the final cleanup strategies are being conducted. 52 ------- MIAMI DRUM SERVICES FLORIDA EPA ID# FLD076027820 Site Description REGION 4 CONGRESSIONAL DIST. 16 Dade County Miami Alias: Biscayne Aquifer Miami Drum Services recycled drums for 15 years on this 1-acre site in a predominantly industrial area of Miami. While the company was in operation, as many as 5,000 drums of various chemical wastes including corrosives, solvents, phenols, and toxic metals were observed on the site. Surface spills and percolation of contaminated wastewater have saturated the soil at the facility. The Biscayne Aquifer, which underlies the site, is contaminated with various toxic organic solvents and heavy metals. The site is about 750 feet from the Medley Well Field, which extracts drinking water from the Biscayne Aquifer during peak demand periods. Groundwater is less than 3 feet below the surface. Dade County obtained a court order to close the facility in 1981. The property, now owned by the County, was to become part of its new mass transit system. The EPA gave Dade County the funds to clean up the site, and the County recommended excavation and off-site disposal of contaminated soil, timed to meet its construction schedule. This site, along with the Northwest 58th Street Lahdfilland the Varsol Spill Site, have been studied together as the "Biscayne Aquifer Sites." Proposed on the NPL as a unit, they were considered to be a serious potential threat to regional water supply. The three sites were eventually listed on the N PL as individual sites. Site Responsibility: This site is being addressed through a combination of Federal, State, County, and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Threats and Contaminants Groundwater contains volatile organic compounds (VOCs), primarily vinyl chloride from former waste disposal activities. On-site soils are contaminated with phenols, heavy metals, oil and grease, pesticides, and other materials from the drum-cleaning operation. March 1990 NPL HAZARDOUS WASTE SITES 53 continued ------- MIAMI DRUM SERVICES Cleanup Approach The site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site. Response Action Status Entire Site: The EPA formally selected the remedies for this site in 1982 and 1985. Cleanup was separated into two phases: source control and groundwater cleanup. Source Control: The EPA accepted the source control strategy proposed by Dade County in 1981. The County mobilized its transportation funds to speed up cleanup activities, and by early 1982, 8,500 cubic yards of contaminated soil had been removed to an off-site disposal facility and almost a million gallons of groundwater were pumped and treated. Later in 1982, the EPA funded the County's cleanup actions and a more intensive study of how contaminated groundwater was moving from the site. The 1982 cleanup activities were adequate to control the source of contaminants, and the site is now a railroad yard for the County Transit Authority. Groundwater: The remedy selected in 1985 was to add air strippers at two water treatment plants. This technology evaporates volatile contaminants out of the water. The State undertook the engineering design for groundwater cleanup and finished it in 1987. The actual cleanup activities were delayed because the State declined to conduct them, but the EPA negotiated a Cooperative Agreement with the local government and a contract for assurances with the State. Construction is expected to be completed by late 1991. Site Facts: Dade County filed suit against the former owner in 1981, seeking recovery of all funds spent for site cleanup, compensatory damages for harm to natural resources, and punitive damages. The EPA filed a cost recovery action. The parties potentially responsible for the contamination settled in 1988 on source control action. Historic preservationists were concerned that the air strippers proposed for cleaning up the groundwater would block the view of the historic Hialeah Water Treatment Plant, but a compromise solved the problem. Environmental Progress The cleanup activities at the Miami Drum Services site have been successful in controlling the source of contaminants, and efforts are being focused on treatment of the groundwater. The EPA has determined that the site does not presently pose an immediate threat to public health or the environment while further actions are being planned to permanently clean up the contaminated groundwater. A 54 ------- MUNISPORT FLORIDA EPA ID# FLD084535442 Site Description REGION 4 CONGRESSIONAL DIST. 17 Da.de County North Miami The Munisport Landfill is a 291-acre, inactive facility. A developer leased the land from the City of North Miami and filled low-lying areas with clean fill and construction debris. By 1974, the landfill was accepting municipal refuse. Between 1972 and 1981, its operators piled several million cubic yards of solid waste 40 feet high, and the facility was eventually shut down for improper disposal practices. The site's operators created eight deep lakes on the site when they excavated the refuse and used debris to cover the piles. Disposal records show that the site accepted domestic garbage, yard refuse, construction debris, and hospital pathological wastes. Three major sampling and monitoring efforts were mounted in the 1980s by the EPA and the City of North Miami. The site is bounded by major roads, Florida International University, and a mangrove swamp, which separates the site from Biscayne Bay. The Bay is classified as an outstanding Florida waterway and nature preserve and is a major recreational area. Mangrove wetlands, which are becoming increasingly rare, are valuable as wildlife habitat. Site Responsibility: This site is being addressed through Federal, State, and potentially responsible parties'actions. NPL LISTING HISTORY Proposed Date: 12/01/82 Final Date: 09/01/83 1\ Threats and Contaminants Pollutants detected in groundwater, soil, and leachate samples include elevated levels of ammonia and low levels of heavy metals, pesticides, and volatile organic compounds (VOCs) from the former waste disposal activities. No public health risk exists under current uses. A threat to the environment exists, however, due to the migration of leachate from the site into the mangrove preserve. Contamination of the preserve can be particularly serious because many pollutants, even at very low levels, can damage aquatic life and can bioaccumulate and concentrate in the food chain. Birds from the rookery in Greyolds Park feed in the mangrove swamp and are threatened by possible contaminants there. March 1990 NPL HAZARDOUS WASTE SITES 55 continued ------- MUNISPORT LANDFILL Cleanup Approach This site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site. Response Action Status Entire Site: The EPA began an intensive study of soil and water pollution at the site in 1987. This investigation explored the nature and extent of pollution problems and recommended the best strategies for final cleanup. A subsequent study of the mangrove preserve was conducted in 1989. The EPA plans to design a system for the collection and treatment of leachate. Closure of the landfill will be conducted under State authority. Site Facts: Environmentalists and the State of Florida are concerned about the threat to aquatic organisms in the preserve and are working with the EPA to develop a cleanup plan for the site. Though no air pollution data are available, nuisance odors led to three citations while the site was active. Environmental Progress After adding this site to the NPL, the EPA performed preliminary investigations and determined that no immediate actions were needed to protect the public at the Munisport Landfill site while further investigations continue and cleanup activities start. 56 ------- NORTHWEST 5 STREET LANDFH* FLORIDA EPA ID# FLD980602643 REGION 4 CONGRESSIONAL DIST. 10 Dade County • Near .the Town of Medley Site Description The Northwest 58th Street Landfill site, near the City of Mia mi Springs, is one of three NPL sites that comprise the Biscayne'/AgL/tferSuperfund Study. The landfill is a 1- square-mile site near Hialeah, along the eastern edge of the Everglades wetlands. From 1952 to 1982, the site operated as a municipal landfill, receiving approximately 60,000 tons of waste in 1952 and increasing annually over the 30 years of operation to over 1,000,000 tons per year. Small quantities of household hazardous'.materials;'such as pesticides, paints, and solvents were considered to be municipal waste, In 1975, the landfill operation initiated a program of providing daily cover to the site; however, prior to this, the operation did not compact wastes or add daily cover. Since 1982, the landfill has received only quarry wastes of water-based paint sludges. The landfill is no longer receiving waste and is undergoing formal closure procedures. Two major groups of public water supply well fields are located downgradient within 2 miles.pf the site.. These wells serve an estimated 750,000 people. • ' " •< '• :•••:.-•;•- ';;'',"."- ".--4 Site Responsibility: this site is befng'addressed through a combination of Federal, State, County, and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Threats and Contaminants Leachate from the landfill has contaminated groundwater with heavy metals such as arsenic and lead, as well as volatile organic compounds (VOCs) such as vinyl chloride. Potential risks to individuals exist if they drink the contaminated groundwater. In 1986, the U.S. Geological Survey identified a leachate plume migrating westerly from the site. The County is selectively pumping well fields and has constructed hydraulic barriers to control the plume. March 1990 NPL HAZARDOUS WASTE SITES 57 continued ------- NORTHWEST 58TH STREET LANDFILL Cleanup Approach The site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site. Response Action Status Entire Site: The cleanup plan to be completed by the parties potentially responsible for the contamination includes: controlling leachate generation by a combination of grading, drainage control, and capping; providing a public water supply to replace approximately 60 wells; and landfill closure. The parties responsible for the contamination completed installing an alternate water supply in 1988 and a leachate interception system in 1989. Additional cover is being applied to the landfill while the design for final site closure continues. The final design for cleaning up the site was approved in the spring of 1990 and is expected to be implemented in the fall, during the historical dry season. Site Facts: The State of Florida has a civil suit pending against Dade County for failure to cease operations by August 1981. The State and County are working together to develop a final plan for closing the facility. The Department of Justice completed all notice requirements to the parties potentially responsible for the contamination and filed the Consent Decree with the court in January 1989. The County has repaid EPA for past cleanup costs and is in compliance with the Consent Decree. Environmental Progress The provision of an alternate water supply and the installation of a leachate control system and additional cover at the Northwest 58th Street Landfill site have reduced the potential for exposure to hazardous materials while the investigations into permanent remedy solutions are taking place. 58 ------- PARRAMORE FLORIDA EPA ID# FLD041140344 REGION 4 CONGRESSIONAL DIST. 02 Gadsden County- Mount Pleasant Site Description The Parramore Surplus site is a 25-acre storage and resale company for Navy and Air Force surplus equipment. Beginning in 1972, Parramore began storing drums on the property. The Florida Department of Environmental Regulations (FDER) inspected the site and found 400 to 600 drums, some of which were leaking and killing the vegetation. The site is located in a low-density residential area with approximately 20 homes in the immediate vicinity of the site. Less than 100 people live within a 1-mile radius of the site. The area surrounding the site is primarily agricultural and forest land. Site Responsibility: This site was addressed through Federal actions. NPL LISTING HISTORY Proposed Date: 12/01/82 Final Date: 09/01/83 Deletion Date: 02/21/89 Threats and Contaminants The soil was contaminated with polychlorinated biphenyls (PCBs), volatile organic compounds (VOCs), and heavy metals including lead. Cleanup Approach This site was addressed in a long-term remedial phase focusing on. source control at the site. March 1990 NPL HAZARDOUS WASTE SITES 59 continued ------- PARRAMORE SURPLUS Response Action Status Source Control: The EPA, the Florida Department of Environmental Regulations (FDER), and the owner of Parramore agreed that Parramore would remove the surface contamination. After the removal was complete, samples were taken of the soil and three new areas of contamination were located. Parramore cleaned these areas as well. Sampling after the second removal in 1983 indicated that the contamination had been removed. In 1985, a modified investigation was conducted by the EPA to determine whether all source materials had been removed and whether there was any groundwater contamination directly related to the site. The investigation determined that all sources of contamination had been successfully removed with the exception of the three small areas that had been the target of the second cleanup. It was determined that the amount of the contamination present in these areas would not damage the environment or threaten public health. A groundwater quality assessment, however, was recommended to assure that no groundwater contamination had occurred from past releases of hazardous substances at the site. Groundwater monitoring wells were installed, followed by two periods of groundwater sampling and analyses to ensure that the groundwater had not been adversely impacted by past releases of hazardous substances. The monitoring was completed in 1987, and the site was found to be within safe standards and poses no threat to human health or the environment. The-site was deleted from the NPL on February 21,1989. , • . . Environmental Progress All cleanup activities, including groundwater monitoring, were completed at the Parramore site and the site was deleted from the NPL in 1989. The cleanup actions have achieved .all established goals for surface contamination and the site is now safe to nearby residents and the environment. 60 ------- PEAK OIL COM FLORIDA EPA ID# FLD004091807 REGION 4 CONGRESSIONAL PIST, 07 Hillsborough County Tampa Site Description The 15-acre Peak Oil/Bay Drum site was constructed and began operations in 1954. Operations involved the use of a refining process to purify used oils and lubrication fluids. Major compounds accepted for recycling were used crank-case oil, hydraulic fluid, and some transformer fluids. An acid/day purification and filtration process that generated sludge and oil-saturated clay was used from 1954 until 1977, and these substances were discharged to three unlined lagoons. Two of the lagoons have been backfilled. The Peak Oil site is located within 2 miles of the Brandon Well Field, which is part of the Hillsborough County water supply system. Surface water from the Peak Oil site drains to a wetland area to the southwest. Several private wells are located in the immediate vicinity of the contaminated site including a 200-foot deep Floridian Aquifer well and a production well at the adjacent Reeves Southeastern Wire Corporation, also on the NPL. Residential neighborhoods, light manufacturing facilities, warehouses, a domestic wastewater plant, a wetland, and Hillsborough County's refuse-to-energy plant are located in the area around the site. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 10/01/84 Final Date: 06/10/86 IV Threats and Contaminants The soils, sludges, surface water, and sediments on site are contaminated with polychlorinated biphenyls (PCBs), volatile organic compounds (VOCs), and heavy metals including arsenic and lead from former process wastes. In addition, the groundwater is contaminated with PCBs. Potential health threats in the area may come from contact with contaminated off-site soils or surface water runoff and from breathing contaminated dust in the air. There are several aquifers and a wetland in the area that may contain contaminants from the site. March 1990 NPL HAZARDOUS WASTE SITES 61 continued ------- PEAK OIL COMPANY Cleanup Approach This site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of the entire site. Response Action Status Immediate Actions: Incineration of contaminants was approved, and, in 1986, contaminated soils were excavated and prepared for test burns in a mobile incinerator. As of 1987, more than 1,500 tons of contaminated soil had been incinerated. In 1989, tanks were cut up and disposed of off site. Used oil, contaminated with PCBs, is currently being disposed of off site. Disposal options for sludges from the tanks are being evaluated. This cleanup action is expected to be completed by late 1990. A cleanup action is currently under way to remove barrels of sludge and oil from tanks stored in the warehouse. Mixed oil/water were removed and taken to an approved off-site facility. Entire Site: The parties potentially responsible for site contamination are studying the nature and extent of pollution at the site. Field activities for an area-wide hydrogeological study began in 1989. Fields activities to identify the source of the contamination also began in 1989; Site Facts: An Administrative Order on Consent for the site source characterization and the area-wide hydrogeological cleanup investigation became effective in 1989. Environmental Progress The treatment of soil and disposal of some liquid wastes have greatly reduced the potential for exposure to hazardous substances at the Peak Oil site. These actions have protected the public health and prevented further environmental damage, while further cleanup activities are being completed. 62 ------- PENSACOLA NAVAL AIR STA FLORIDA EPA ID# FL9170024567 Site Description REGION 4 CONGRESSIONAL DIST. 01 Escambia County 6 miles southwest of Pensacola The Naval Air Station (NAS) Pensacola is located on approximately 5,875 acres and is the home of two major industrial tenant commands: the Naval Aviation Depot and the Public Works Center. Work in support of the base mission includes fuel storage and transportation systems and depot-level, maintenance and repair of aircraft and engines. Maintenance activities over the years generated a variety of disposed materials including waste materials from construction activities and municipal solid waste and municipal wastewater treatment plant sludge. Miscellaneous industrial wastes including waste oils or solvents, paints, electroplating, radium paint wastes, and insecticides were discharged to storm sewers until 1973, when an industrial sewer and wastewater treatment system were installed. Current disposal practices are regularly monitored for conformance with local. State, and Federal regulations. The groundwater aquifer at NAS Pensacola extends to a depth of approximately 400 feet. There are three drinking water wells tapping the upper aquifer on the facility. An estimated 15,000 people on NAS Pensacola and 30,000 customers of Peoples' Water Co. obtain drinking water from wells within 3 miles of the hazardous substances on site. The surface water bodies surrounding the site include Pensacola Bay and a tidal creek known as Bayou Grande. These surface waters are classified by the Florida Department of Environmental Regulation as Class 111 waters: for recreation use and the propagation and management offish and wildlife. Site Responsibility: This site is being addressed through Federal actions. Threats and Contaminants NPL. LISTING HISTORY Proposed Date: 07/14/89 Final Date: 11/21/89 Volatile organic compounds (VOCs), including benzene and ethylbenzene from former waste disposal practices, have been found in the monitoring wells. Arsenic and pesticide compounds have been detected in soil samples taken at a pesticide mixing area. Heavy metals have been detected in surface water sediment Drinking water wells are currently assumed to be upgradientoi the base. A large hazardous waste landfill is located next to the base golf course and a picnic area. The Base Marina is located where a storm drain from the electroplating shops emptied into the bayou. Direct contact during recreation is a possibility for those on- base and could pose a health risk. March 1990 NPL HAZARDOUS WASTE SITES 63 continued ------- PENSACOLA NAVAL AIR STATION Cleanup Approach The site is being addressed in a single long-term remedial phase directed at cleanup of the entire site. Response Action Status Entire Site: The Navy plans to further investigate the spills of contaminants and the migration of the hazardous wastes at 37 acres of the site identified in studies. A workplan for investigating the potential sources was prepared and submitted to the EPA. The investigation is scheduled to begin in 1990, after which recommendations for a final remedy method will be made by the EPA. ' Site Facts: The Navy identified 37 potential sources of contamination during studies conducted under the Department of Defense (DOD) Installation Restoration Program (IRP). The program seeks to identify, investigate, and control contamination from hazardous materials. The Navy's studies will be conducted through a permit issued under the Resource Conservation and Recovery Act (RCRA) and a Federal Facility Agreement. Environmental Progress After adding the NAS Pensacola site to the NPL, the EPA evaluated conditions and determined that no immediate threat to human health or the environment presently exists. The ongoing investigations into the extent of contamination will determine the type of permanent remedy needed at the site. 64 ------- PEPPERS STEE AND ALLOY CO FLORIDA EPA ID# FLD032544587 Site Description REGION 4 CONGRESSIONAL DIST. 18 Dade County 10 miles northwest of Miami The 30-acre Peppers Steel and Alloy Company site is located in an industrial area with no sewage system and is near three other NPL sites. Since the mid-1960s, the site has been the location of several businesses. On-site activities included manufacturing of batteries, pre-cast concrete products, and fiberglass boats, as well as the repair and service of trucks and heavy equipment. Also, sandblasting.and painting services, a concrete batching plant, and an automobile scrap operation are located on the site.' Peppers Steel's activities .included recycling of electrical transformers, where waste oil containing polychlorinated biphenyls (PCBs} was dumped in wetlands on the site. Various trash and waste products from these activities, including parts of rusted machinery, vehicles, aircraft, oil tanks, transformers, underground storage tanks, and batteries have been deposited at the site. Contamination has been identified in the soil, sediments, and groundwater in and around the site. The site area is flat, and in many places the groundwater is only 1 to 2 feet below the surface. Site Responsibility: This site is being addressed through Federal and potentially responsible parties'actions. NPL LISTING HISTORY Proposed Date: 09/01/83 Final Date: 09/01/84 Threats and Contaminants IA PCBs, volatile organic compounds (VOCs), and heavy metals such as lead and arsenic from former site activities have been detected in the groundwater, sediments, and soil. Accidental ingestion of and direct contact with contaminated soil, groundwater, and sediments could pose a health hazard to the public. March 1990 NPL HAZARDOUS WASTE SITES 65 continued ------- PEPPERS STEEL AND ALLOY COMPANY Cleanup Approach This site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of the entire site. Response Action Status ', Initial Actions: Early in 1983, the EPA conducted a geophysical survey of the site and identified about a dozen zones requiring further investigation. Soil samples determined that PCBs were present in at least two zones. The EPA removed soil in these zones and oil floating on the shallow aquifer underlying the site. The EPA also drilled observation wells and sampled on-site wells and surface water in the immediate area. Entire Site: The following actions were chosen by the EPA for the site cleanup: (1) collection and off-site disposal of all free oil; (2) excavation of soils containing PCBs, lead, and arsenic; (3) solidification of the contaminated soil with a cement-type mixture to prevent the migration of the contaminants; (4) institutional controls such as deed restrictions to ensure that future land use is compatible with the site; and (5) monitoring groundwater to ensure the effectiveness of the cleanup. Florida Power and Light started the cleanup of the site in 1987. The site cleanup is complete and the EPA is currently drafting a final report. The EPA plans to remove the site from the NPL in 1994. Site Facts: The EPA, the State of Florida, the County of Dade, and Florida Power and Light signed a Consent Decree in 1987. Based on this decree, Florida Power and Light took responsibility for the design and implementation of the cleanup procedure. The site is planned to be deleted from the NPL by 1994, after a 5-year review. Environmental Progress All cleanup activities, including the removal of soils and liquid waste, are completed at the Peppers Steel and Alloy Company site. The site is again safe to nearby residents and the environment while the EPA conducts a final review before deleting the site from the NPL 66 ------- PETROLEUM P CORPORATIO FLORIDA EPA ID# FLD980798698 Site Description REGION 4 CONGRESSIONAL DIST. 14 Broward County Pembroke Park Alias: Pembroke Road Petroleum Products Corporation refined, stored, and recycled oil on this 2-acre site from 1952 to 1972. Residents in a nearby trailer park became concerned when heavy rain triggered an overflow of a disposal pit and produced an oil slick on a lake on the trailer park grounds in 1970. The company initiated major changes in its operation and sold most of its property. The northern half of the property was cleared and the disposal pit was filled in, but a tank farm remained. In 1979, the State issued two warning notices to Petroleum Products because of oil discharges from the tank farm area. The company cleaned up two oil-soaked areas, rehabilitated the tank farm berm, and filled in low spots with clean fill. The site was converted to the Pembroke Park Mini Warehouses in 1985 and now houses small industrial and commercial businesses. The area surrounding the site is a rapidly developing and growing residential area which supports a variety of recreational and industrial activities. The population of Pembroke Park is 20,000. Approximately 150 people live in two trailer parks adjacent to the site. There are more than 200 homes using public wells within 1/4 mile of the site. The Hallandale municipal well field is 2 miles southeast of the site, and the Hollywood municipal well field lies 3 miles northwest of the site; these well fields serve 150,000 people. Located within the trailer park and a nearby golf course are a number of man- made lakes that are used for irrigation. Site Responsibility: This site is being addressed through a combination of Federal, State, and potentially responsible parties' actions. IMPL LISTING HISTORY Proposed Date: 04/01/85 Final Date: 07/01/87 L\ Threats and Contaminants Groundwater is contaminated with oil, heavy metals including lead and chromium, and volatile organic compounds (VOCs) including benzene from the former process wastes. The soil is contaminated with lead and arsenic, and sludges and surface water runoff are contaminated with lead. The well fields near the site draw water from the deep Floridian Aquifer. The aquifer beneath the site is connected to the Floridian, but has not contaminated it. Because most of the contaminated soil at the site is underneath asphalt, there is little risk that people could come in direct contact with it until cleanup activities begin. The lakes at the nearby trailer park and golf course could pose a threat to people who accidentally drink the contaminated water. March 1990 NPL HAZARDOUS WASTE SITES 67 continued ------- PETROLEUM PRODUCTS CORPORATION Cleanup Approach The site is being addressed in three stages: immediate actions and two long-term remedial phases focusing on soil and groundwater cleanup. Response Action Status Immediate Actions: In 1985, Petroleum Products removed the drums, storage tanks, and contaminated sludge from the site and transported the materials to a federally approved disposal facility. An oil recovery system was installed for 1 month in 1985 to facilitate the removal of contaminants. The State installed a recovery system in 1987, and approximately 2,400 gallons of oil waste were recovered from the aquifer below the site. The tank farm was dismantled and fenced to prevent trespassing. Soil: The Florida Department of Environmental Regulation (FDER) is assessing an alternative called soil washing to clean up the contamination at the site. Soil washing is a process through which contaminants are extracted by injecting a water-based solution into the soil and then pumping the mixture. The study is expected to be completed in 1990, at which time a final selection of the cleanup technology will be made by the EPA and the FDER. Groundwater: The EPA will conduct a study, scheduled to begin in 1991, to determine the type and extent of the contamination in the aquifer beneath the site. In the course of the study, various alternatives for cleaning the groundwater will be evaluated. Once the study has been completed and reviewed, the EPA will select a final cleanup remedy. Site Facts: The EPA and Petroleum Products entered into a Consent Order in 1985. Under this order, the company agreed to take immediate action at the site to reduce threats to human health and the environment. Environmental Progress The removal of the major sources of contamination at the Petroleum Products site has significantly reduced the potential for exposure to contaminants and reduced the level of contaminants in groundwater while the investigations leading to a final cleanup remedy are taking place. 68 ------- PICKETTVILLE^ ROAD LANDFIL FLORIDA EPA ID# FLD980556351 REGION 4 CONGRESSIONAL DIST. 03 Duval County 5 miles northwest of Jacksonville Site Description The Pickettville Road Landfill site covers 52 acres northwest of Jacksonville. The site began operations in the early 1940s on a limited basis; full-scale operations started in 1968 when the City of Jacksonville began using the site for a municipal dump. The site was dedicated to the disposal of hazardous and solid wastes in 1971. Wastes deposited at the landfill included waste oil, liquid acid waste from batteries, battery casings, and polychlorinated biphenyls (RGBs). All waste disposal ceased in 1977, and the site was backfilled, graded, and seeded. In 1981, the EPA detected contaminants in groundwater. Additional backfilling and regrading were completed in 1983 to curb on-site erosion and leachate draining into nearby Little Six Mile Creek. The site is located in a semi-rural area of mixed uses including residences, commercial establishments, and light industry. There are over 300 residences and two schools located within a 1-mile radius of the site. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Threats and Contaminants Groundwater is contaminated with heavy metals including arsenic and lead, and volatile organic compounds (VOCs) including benzene and pyrene from former waste disposal activities. Private wells contain barium. Sediments from Little Six Mile Creek are contaminated with heavy metals, and the soil also is contaminated with heavy metals, as well as PCBs and VOCs. People who accidentally consume contaminated water may be at risk. Well water is used for irrigating gardens, and contaminants may accumulate in fruits and vegetables. Fish from Little Six Mile Creek may contain bioaccumulated contaminants from the site leachate. March 1990 NPL HAZARDOUS WASTE SITES 69 continued ------- PICKETTVILLE ROAD LANDFILL Cleanup Approach The site is being addressed in two stages: initial actions and a long-term remedial phase focusing on cleanup of the entire site. Response Action Status Initial Actions: As an initial measure to prevent potential exposure and spread of site contaminants, the site was backfilled, graded, and seeded in 1977 and again in 1983. Entire site: The parties potentially responsible for the site contamination are expected to have the study of the nature and extent of the contamination completed in 1990. This study will recommend alternatives for cleaning up the site, and the EPA will select the most appropriate remedies for site cleanup. The engineering work to design a cleanup method and the actual cleanup activities will begin following remedy selection. Site Facts: In 1988, the EPA and the parties potentially responsible for contamination at the site signed an Administrative Order. Under this order, the responsible parties will investigate the extent of contamination at the site. Environmental Progress After adding the Pickettville Road Landfill site to the NPL, the EPA conducted an evaluation of site conditions and determined that the initial actions taken at the site have controlled the immediate threats to public health or the environment while the study into the cleanup alternatives is being conducted. 70 ------- PIONEER SAND I COMPANY FLORIDA EPA ID# FLD056116965 Site Description REGION 4 CONGRESSIONAL DIST. 01 Escambia County 5 miles west of Pensacola The 11-acre Pioneer Sand Company site is an inactive quarry that was licensed in 1974 to receive shredded auto parts, construction debris, and various industrial sludges. Between 1974 and 1978, phenols and resin compounds were deposited on the site by Newport Industries. Domestic and industrial wastes, including plating sludges, were received from the Pensacola Naval Air Station. Approximately 75% of the site is an excavation pit, while the remaining 25% is the fill area where the wastes were deposited. In 1981, the Florida Department of Environmental Regulation (FDER) did not renew the disposal permit and ordered the dumping to cease. The State and the EPA detected contaminants in the soil. A monitoring well installed by the company and one of the disposal ponds were also found to be contaminated. A well field for the City of Pensacola, which has a population of approximately 67,000, is located within 3 miles of the site. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 I Threats and Contaminants A monitoring well and surface water in the lagoon contain elevated levels of heavy metals including chromium and lead from the former waste disposal activities. Leachate is contaminated with various heavy metals, volatile organic compounds (VOCs), and pentachlorophenol (PCP). The soil is contaminated with polychlorinated biphenyls (PCBs) and heavy metals. Because the EPA took immediate action to remove the contaminated soil, and the parties potentially responsible for the contamination are currently monitoring the site, there is little threat to the area population. March 1990 NPL HAZARDOUS WASTE SITES 71 continued ------- PIONEER SAND COMPANY Cleanup Approach This site is being addressed in two stages: an immediate action and a long-term remedial phase focusing on cleanup of the entire site. Response Action Status Immediate Action: In 1986, the EPA excavated 20 tons of contaminated soil and transported it to a federally approved facility. Entire Site: In 1986, the EPA selected a remedy to clean up the site which includes: closing the landfill and sludge pond areas according to Federal and State procedures; collecting the leachate, treating it and disposing of it on site; treating surface water and discharging it on site; and long-term maintenance activities. The parties potentially responsible for site contamination removed trash from the site and installed a security fence. During their investigation prior to the design of a method for cleaning up the site, the potentially responsible parties discovered a light non-aqueous phase liquid (LNAPL) in the landfilled area. They have completed a treatability study for the LNAPL. The design for the cleanup of the site is complete. The cleanup activity is scheduled to begin in 1990. Site Facts: The EPA and the parties potentially responsible for the site contamination entered into a Consent Decree in 1988. In this action, they agreed to clean up the site. Environmental Progress The removal of contaminated soils greatly reduced the potential for exposure to hazardous materials at the Pioneer Sand site while further investigations and cleanup activities take place. 72 ------- PIPER AIRC CORPORATION FLORIDA EPA ID# FLD004054284 REGION 4 CONGRESSIONAL DIST, 11 Indian River County Vero Beach Alias: Vero Beach Wellfield Site Description The Piper Aircraft Corporation site covers 90 acres in Vero Beach. The company began assembling and painting light aircraft in 1957 at the southern end of the Vero Beach . Municipal Airport. Chemicals used in these operations are stored in underground storage tanks. During routine/testing of the City water supply in 1978, the presence of contaminants was detected. An area search and tank testing revealed the source to be a leaky pipe-fitting on a Piper Aircraft storage tank. Well #15 of the City of Vero Beach well field was subsequently shut down due to contamination. Six months later, the City developed two other wells to replace the one that was closed. In 1981, the Florida Department of,Environmental Regulation (FDER) took actions against the company, ' ; after which Piper repaired the faulty equipment and began pumping out contaminated groundwater. Approximately 10,000 people obtain drinking water from public wells located within 1 mile of the site. Site Responsibility: This site is being addressed through a combination of Federal, State, and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 06/01/86 Final Date: 02/16/90 Threats and Contaminants Groundwater in the on-site shallow aquifer, surface water, and the water in the Main Canal on the site are contaminated with trichloroethylene (TCE) and other volatile organic compounds (VOCs) from the leaking underground storage tank. Although a number of people obtain drinking water from nearby municipal wells, the health concerns are minimal because the city wells were relocated and are being constantly monitored. Oysters and fish from the Main Canal are contaminated with low levels of TCE and present a health risk if they are eaten. March 1990 NPL HAZARDOUS WASTE SITES 73 continued ------- PIPER AIRCRAFT CORPORATION Cleanup Approach The site is being addressed in two stages: an initial action and a long-term remedial phase focusing on cleanup of the entire site. Response Action Status Initial Action: Since 1981, when groundwater treatment began, an estimated 2,000 gallons of solvents have been removed by pumping the contaminated water from the site through closed conduits 1/2 mile to the Main Canal. The contaminated water is sprayed into the air to remove the contaminants and then discharged into the Main Canal. Entire Site: Piper Aircraft is currently studying the type and extent of contamination at the site. Once the study is completed, alternatives for cleaning up the site will be recommended. The EPA will then select cleanup technologies best suited to a final remedy for the site contamination. Site Facts: In 1981, the State and Piper Aircraft entered into a Consent Agreement requiring the company to perform repairs on equipment and to treat the contaminated groundwater. Environmental Progress By moving municipal wells and by pumping and air-treating the contaminated groundwater from the Piper Aircraft site, the potential for exposure to hazardous substances has been significantly reduced. These actions have protected the public water supply while the investigations into a permanent cleanup remedy are taking place. 74 ------- GALVANIZING CORPORATION FLORIDA EPA ID# FLD000824896 Site Description TU- REGION 4 * CONGRESSIONAL DIST. 07 Hillsborough County Highway 574, east of Tampa The Reeves Southeastern Galvanizing Corporation site encompasses 2 areas on 28 acres and includes the Reeves Southeastern Galvanizing Site (RSEG) covering 17 acres and the Reeves Southeastern Wire Site (RSEW) covering 11 acres. Beginning in the 1960s, spent caustic, rinse, and acid process wastes generated at RSEG and RSEW were neutralized and discharged to storage ponds. It is believed that plating wastes were discharged in the same manner. These practices have caused contamination of groundwater and surface water. When Hillsborough County issued a notice of violation to the company in 1974, the company responded by upgrading its existing wastewater treatment facility to an advanced system to neutralize the acid and to remove 90% of the heavy metals. One pond at RSEW has been backfilled; two have not, but they are not used. Two ponds exist at the RSEG area but are not presently used. Residential neighborhoods, light manufacturing facilities, warehouses, a wastewater treatment plant, and a refuse-to-energy plant are located in the area surrounding the site. County- owned water supply wells are located approximately 1 mile upgradientoi the site. There are approximately 56,000 people residing within 3 miles of the site. Site Responsibility: This site is being addressed through Federal and potentially responsible parties'actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Threats and Contaminants Groundwater is contaminated with heavy metals such as chromium and aluminum from former process wastes. The soil and surface water are also contaminated with heavy metals, primarily zinc. Although sampling has shown municipal wells are not contaminated, private wells have not been sampled. Since the groundwater is contaminated, it may potentially affect the drinking water wells. In addition to drinking polluted water, people who touch or accidentally ingest contaminated surface water or soils may be at risk. March 1990 NPL HAZARDOUS WASTE SITES 75 continued ------- REEVES SOUTHEASTERN GALVANIZING CORPORATION Cleanup Approach This site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site.

This investigation will determine the exact contaminants and the extent of damage to the soil and surface water. Once the investigation is completed in 1991, various alternatives will be recommended to clean up the site. The EPA will then select the most appropriate remedies for site cleanup. Site Facts: In 1989, the EPA and the parties potentially responsible for contamination at the site signed an Administrative Order on Consent Unde'r'this Order, the parties will conduct a study of the site with EPA monitoring. ,' ' Environmental Progress After adding this site to the NPL, the EPA performed preliminary investigations and determined that there were no immediate threats from the site to public health or the environment while further investigations and cleanup activities take place. 76 ------- SAPP BATTERY^ SALVAGE FLORIDA EPA ID# FLD980602882 Site Description REGION 4 CONGRESSIONAL DIST. 02 Jackson County Alford The 45-acre Sapp Battery site is composed of three swamps connected by small channels. In 1970, Sapp Battery Service, Inc. began an operation to recover lead from used batteries, dumping the acid outside the plant, recovering the lead, and disposing of the broken battery casings in an on-site man-made fishing pond. By 1977, the acid discharge began killing nearby cypress trees. Dead and discolored vegetation, as well as strong sulfurous odors, have been noted along the drainage route from the site. Sapp Battery undertook several steps to alleviate the problem; however, none of them were effective. The owner stopped operations and abandoned the site in 1980. The site is currently contaminating the Floridian Aquifer, which provides drinking water for most of the area residents who depend on private wells. There are approximately 3,000 people living within a 3-mile radius of the site. Site Responsibility: This site is being addressed through Federal and State actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Threats and Contaminants The groundwater and surface water are contaminated with lead from battery wastes. Soil contaminants include heavy metals such as lead, antimony, and cadmium. People may be exposed to heavy metals if they drink contaminated water or if they accidentally consume contaminated soil or other contaminated materials. Cleanup Approach This site is being addressed in two stages: emergency actions and a long-term remedial phase focusing on cleanup of the entire site. March 1990 NPL HAZARDOUS WASTE SITES 77 continued ------- SAPP BATTERY SALVAGE Response Action Status Emergency Actions: In 1980, the EPA undertook an emergency cleanup action, which resulted in a temporary restoration of pH levels similar to background levels downstream from the site. In 1984, the EPA constructed a berm to contain surface water and moved contaminated soil and sludges to a chemical management facility. In the same year, the Florida Department of Environmental Resources excavated and removed roughly 9,000 cubic yards of highly contaminated soil from the site. Entire Site: In 1986, the EPA selected cleanup plans for the site that include: (1) excavating soils and sediments; (2) stabilizing excavated soils and sediments; (3) on-site disposal of the solidified materials into a cell built to sanitary landfill standards; (4) removal and treatment of groundwater in the aquifers under the site; (5) treatment and discharge of contaminated surface water from the on-site swamp and off-site Steele City Bay; and (6) a monitoring program for drinking water wells within a 1-mile radius. The engineering design of the approved cleanup activities is expected to be completed early in 1990. Site Facts: The cleanup plan for sediment excavation from Steele City Bay is being re- evaluated, as excavation may reintroduce contaminants into surface.waters. It may be more ecologically sound to leave the sediments in place. Environmental Progress The containment and removal of contaminated materials have greatly reduced the potential for exposure to hazardous materials while further investigations and cleanup activities take place at the Sapp Battery Salvage site. 78 ------- SCHUYLKILL IV® CORPORATIO FLORIDA EPA ID# FLD062794003 REGION 4 CONGRESSIONAL DIST. 09 Hillsborough County Plant City Site Description Schuylkill Metals Corporation (SMC) recovered lead from storage batteries on this 17 1/2-acre site from 1972 through 1986. Before 1981, acid washdown from wastewater was stored in a 2-acre unlined wastewater holding pond. Initially, lime was used to adjust the pH of the wastewater in the holding pond, and later, ammonia was used for this purpose. The wastewater treatment system was upgraded in 1981 and all wastewater was treated with sodium hydroxide for pH adjustment and was discharged under permit to the publicly owned treatment works. Leachate containing heavy metals and sulfuric acid is migrating from the unlined impoundments into an adjacent drainage ditch that empties into Pemberton Creek. Heavy metals and ammonia contaminate the groundwater on site. High levels of lead were found in the drainage ditch on site. The site is bounded by agricultural land and a'housing development. Approximately 19,000 residents live within 3 miles. A junior high school, an elementary school, and a hospital are located within a mile of the site. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. IMPL LISTING HISTORY Proposed Date: 12/01/82 Final Date: 09/01/83 Threats and Contaminants Groundwater contains contamination from heavy metals including lead and chromium, as well as sulfate. Very high levels of lead were also found in the subsoil, surface water, and sediments in a ditch on site that drains to Pemberton Creek and Marsh, an environmentally sensitive area. People could be exposed to heavy metals in the contaminated groundwater. Direct contact with or accidental ingestion of lead in the soil is unlikely because the area is fenced, but trespassers could be exposed. March 1990 NPL HAZARDOUS WASTE SITES 79 continued ------- SCHUYLKILL METAL CORPORATION Cleanup Approach This site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site. Response Action Status Entire Site: The State of Florida and SMC, the party responsible for contamination at the site, have completed a study of the nature and extent of site contamination and have evaluated the various technologies available for cleanup. Further studies on the marsh are being conducted, and treatability studies for the soils also are being conducted. Results from both of these studies in progress are scheduled to be completed in 1990. The EPA will then select the most appropriate remedies for site cleanup, and design of the selected remedy for cleaning up the site is slated for 1991. Site Facts: A Consent Order between SMC and the Florida Department of Environmental Regulation was signed in 1986 to study site contamination and the various methods to clean it up. Environmental Progress After adding this site to the NPL, the EPA performed preliminary site investigations and determined that there were no immediate threats to public health or the environment at the Schuylkill Metal site while further investigations and cleanup activities are being conducted. 80 ------- SHERWOOD MEDICAL FLORIDA EPA ID# FLD043861392 REGION 4 CONGRESSIONAL DIST. 04 Volusia County 3 miles north of Deland Alias: Sherwood Medical Industries Site Description The 43-acre Sherwood Medical site is currently occupied by several manufacturing buildings, a biological laboratory, sizeable parking areas, and additional structures, including a wastewater treatment facility built in 1983. Sherwood Medical Industries has used the property since 1959 for the manufacturing of medical supplies, primarily hypodermic needles. Industrial operations currently include grinding, cleaning, hub processing, and de-coring of stainless steel and aluminum parts used to manufacture hypodermic syringes. Sherwood also molds plastic syringes and conducts in-house laboratory work. The Sherwood facility pumps approximately 175,000 gallons'of water per day from the underlying Floridian Aquifer. Water drawn for industrial needs is used for cleaning, manufacturing, and cooling/evaporation processes. Several manufacturing steps result in wastewater which must be treated. The industrial wastewater facility on the site is licensed by the Florida Department of Environmental Resources (FDER) to receive and treat wastewater from the plant and to discharge the resulting effluent. The treated effluent is currently disposed by percolation and evaporation. In 1985, Sherwood Medical Industries installed an air stripper to treat production water used in the facility's operations. Between 1971 and 1980, the company disposed of about two tons of liquid and sludge waste into two unlined percolation ponds. During this time, solids were removed from the ponds and placed into on-site, unlined impoundments. In 1982, the Sherwood site was placed on the NPL at the request of the State of Florida because of the threat of contamination from wastes stored in the holding ponds and impoundments. Subsequent testing conducted by Sherwood Medical and the State revealed groundwater contamination in on-site wells. Fifteen residences are in the immediate area of the site, and new residential developments are nearby. Recreational Lake Miller borders the site. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 09/01/83 Threats and Contaminants The groundwater is contaminated with volatile organic compounds (VOCs) and chromium from former process wastes. The movement of contaminated groundwater on the site could contaminate wells in the area. Drinking contaminated water would also threaten human health. March 1990 NPL HAZARDOUS WASTE SITES 81 continued ------- SHERWOOD MEDICAL Cleanup Approach This site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site. Response Action Status Entire Site: In 1985, Sherwood Medical notified the EPA that they would perform a focused investigation at the site. During the investigation, Florida Health and Rehabilitation Services received health-related complaints concerning private wells from nearby residents. Chlorinated solvents were detected in samples from the on-site domestic water supply well, but no violations of drinking water standards were found in samples from nearby private wells. In 1987, the FDER asked Sherwood to sample the on-site water wells and a downgradient residential well to assess the extent of contamination and to evaluate the need for immediate cleanup activities to control and treat the contamination of the Floridian Aquifer. The FDER recommended that the aquifer be treated prior to the completion of the entire site evaluation. Currently, Sherwood Medical is testing all private wells immediately adjacent to the site along Kepler Road every 6 months. Site Facts: The EPA and Sherwood Medical signed an Administrative Order on Consent for Sherwood to study contamination at the site. Environmental Prpgfess, The monitoring activities being performed at the Sherwood Medical site ensure that nearby residents are not exposed to hazardous materials while further investigations and cleanup activities take place. 82 ------- STANDARD A BUMPER FLORIDA EPA ID# FLD004126520 Site Description REGION 4 CONGRESSIONAL DIST. 17 Dade County Hialeah, north of Miami International Airport The Standard Auto Bumper Corporation has electroplated automobile bumpers, furniture, and other metal objects with chrome on this 3/4-acre site since 1959. Before 1972, wastewater from the electroplating and stripping process was discharged into a ditch between the process building and railroad tracks. It was allowed to drain to the north, eventually percolating into the ground. In 1972, the company began treating the plating waste before discharging it into a septic tank/percolation pit and drain field system. Since 1979, treated wastewater has been discharged into the Hialeah sewer system. The metal-containing sludge from the treatment is transported to an EPA- approved hazardous waste facility. Currently, approximately 2,000 to 3,000 gallons per day of wastewater are sent to a concrete diked area, where it is treated to convert hexavalent chromium to the less toxic trivalent state before being discharged into the Hialeah sewer system. In 1985 and 1987, the EPA detected heavy metals in surface soil, subsurface soil, and groundwater on the site. The most extensive contamination was near the drainage pathway. The site is in the recharge zone of the Biscayne Aquifer, which is a sole source supply of drinking water for all of Dade County. High concentrations of contaminants also were found in the drain field system and percolation pits used prior to 1972. It is unclear exactly what was placed in the pits. Four municipal well fields that supply drinking water to approximately 750,000 people are within 3 miles of the site. One well is within 4,200 feet of the site. Wells in the contaminated area have been taken out of service. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 06/24/88 Final Date: 10/04/89 March 1990 NPL HAZARDOUS WASTE SITES 83 continued ------- STANDARD AUTO BUMPER Threats and Contaminants Heavy metals including lead, cadmium, copper, chromium, and nickel from former waste disposal practices contaminate the on-site groundwater, surface soil, and subsurface soil. Potential risks to public health exist from direct contact with on-site industrial well water. Risks also exist, especially for employees, from accidentally eating, inhaling, or touching the contaminated soil and dust. The site is partially fenced and guarded by dogs to reduce access to the site. Private drinking wells located downgradient of the site may also pose a health concern. Potential threats to the environment include the migration of contaminants through groundwater flow, dust and vapor particles traveling in the air, runoff from rainfall, and biota which may accumulate contaminants from the soil, surface water, or groundwater. Cleanup Approach This site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of the entire site. Response Action Status Immediate Actions: In 1989, Standard Auto Bumper began excavating non-hazardous waste soils and transporting them to solid waste landfills. They also excavated the sludge pit and disposed of waste in a federally approved hazardous waste disposal facility. Contaminated soil was taken either to an appropriate solid waste landfill or a hazardous waste facility. Entire Site: Standard Auto will use the Expanded Site Investigation done by the EPA in 1987 and additional studies to determine the nature and extent of heavy metal contamination at the site and will study the feasibility of the alternative cleanup strategies. These studies are scheduled to be completed in 1990, with design of the EPA's selected remedy to begin that same year. The cleanup activities will focus on the groundwater contamination. Site Facts: Standard Auto Bumper and the EPA signed an Administrative Order for the removal of contaminants in 1989, which enforces a plan for remedial action agreed upon between Dade County and Standard Auto. Environmental Progress The removal of contaminated sludges and soils has greatly reduced the potential for exposure to contamination at the Standard Auto Bumper site. These actions have helped to protect the public health and the environment while further cleanup activities take place. 84 ------- SYDNEY MIN SLUDGE PO FLORIDA EPA ID# FLD000648055 Site Description REGION 4 CONGRESSIONAL DIST. 07 Hillsborough County Brandon Alias: Hillsborough County Sydney Mine The Sydney Mine Sludge Ponds site is a 9 1/2-acre former disposal site that was strip- mined for phosphate rock from the 1930s through the 1950s. In late 1973, Hillsborough County leased a portion of the Sydney Mine site from American Cyanamid and constructed a sludge disposal pond. The pond received wastes from grease traps, septage waste, and waste oil. In 1979, the waste disposal site was expanded and modified. At that time, the operation consisted of two primary impoundments: a1 1/2- acre septage pond and a 1/2-acre waste oil pond. About 16 million gallons of waste including sludge, grease trappings, cutting oil, and other, types of waste oil were placed in the two ponds by haulers serving homes, schools, hospitals, and manufacturing and commercial facilities in the area. A third impoundment was located adjacent to the east dike of the septage pond and was reportedly used for disposal on only a few occasions. Waste disposal activities ended in 1981, and Waste Management, Inc. purchased the property that same year. EPA tests in 1979 found contaminants in the ponds and in groundwater under the site. Approximately 4,000 people within 3 miles of the site draw water from the underlying Floridian Aquifer. Site Responsibility: This site is being addressed through Federal, County, and potentially responsible parties'actions. NPL LISTING HISTORY Proposed Date: 06/01/88 Final Date: 10/01/89 Threats and Contaminants The groundwater is contaminated with volatile organic chemicals (VOCs) including toluene, .benzene, and xylene, as well as heavy metals including cadmium from former process wastes. Site workers and trespassers could be exposed to contaminated groundwater, as well as to chemicals that enter the air during the treatment process. Cleanup Approach This site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of the entire site. March 1990 NPL HAZARDOUS WASTE SITES 85 continued ------- SYDNEY MINE SLUDGE PONDS Response Action Status Immediate Actions: The County constructed an underground slurry wall around the ponds to prevent contaminants from escaping and groundwater from entering. Contaminated groundwater within the wall is being extracted, treated, and sprayed on the surface. Surface cleaning consisted of excavation and incineration of more than 12,000 cubic yards of contaminated materials. By 1989, the groundwater system treated more than 41 million gallons of water. The sludge from the site has been burned under controlled conditions to break down the contaminants. Entire Site: The EPA will be monitoring the effectiveness of the existing pump and treat system as well as modifications to the system, if necessary, and will ensure that the system operates until sampling indicates that concentration levels of contaminants have been reduced and remain at acceptable levels. Site Facts: Some of the parties potentially responsible for the contamination of the site were issued an order to operate the groundwater treatment system since they had not voluntarily agreed to do so. These parties have been operating the system since mid-1989, and operation of the groundwater treatment system is ongoing. Environmental Progress The construction of a slurry wall and the treatment of contaminated soils, sludges, and groundwater have greatly reduced the potential for exposure to hazardous substances at the Sydney Mine Sludge Ponds. These actions have helped to protect the public health and the environment while further investigations and groundwater treatment take place. 86 ------- TAYLOR ROAD LANDFILL FLORIDA EPA ID#,FLD980494959 Site Description REGION 4 CONGRESSIONAL DIST. 07 .Hillsborough County 1/8 mile north of Seffher The Taylor Road Landfill site consists of 40 acres. It is next to two other municipal landfills; the Department of Transportation (DOT) Borrow Pit Landfill and the Hillsborough Heights Landfill. These three landfills occupy a total of 200 acres. The Taylor Road Landfill operated from 1975 to 1980, and the DOT Borrow Pit Landfill and Hillsborough Heights Landfill both operated from 1980 to 1984. The three landfills were used for the disposal of municipal refuse, but unknown quantities of industrial wastes may have been dumped at the sites as well. The community around the site,is mainly residential and agricultural. The closest residence is less than 1/8 mile from the site, and the estimated population of the Seffner area is 27,000. Two schools are located within 1/2 mile of the site. Approximately 580 wells are within 1 mile of the facility, and a community well system that serves 2,500 people is located 1 mile downslope from the landfill. The community northeast of Seffner includes dairy farms, two of which are located between 1/4 and 1/2 mile downslope from the landfills. Site Responsibility: This site is being addressed through a combination of Federal and County actions. IMPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Threats and Contaminants Private wells in the area are contaminated with volatile organic compounds (VOCs) including benzene and vinyl chloride and heavy metals including lead from the former waste disposal activities at the site. Consuming contaminated groundwater and dairy products could pose a health hazard to people. At one time, methane gas from the landfill was detected at concentrations above the lower explosive limit near residences adjacent to the site; the County installed a gas collection system in an attempt to correct this problem. The Floridian Aquifer is the main source of potable water in the area, and extensive sampling confirms that it is contaminated. March 1990 NPL HAZARDOUS WASTE SITES 87 continued ------- TAYLOR ROAD LANDFILL Cleanup Approach The site is being addressed in two stages: immediate actions and a long-term remedial phase designed to clean up the entire site. Response Action Status Immediate Actions: In 1983, the Hillsborough County Utilities Department installed a cap, drainage ditches, and methane gas control systems around each of the landfills. The County also extended the water supply system to affected residences in the contaminated area south of the landfill. At this time, the landfills have been capped and closed, and access to the three landfills is restricted, because each is fenced and locked. Entire Site: The EPA has started to investigate the site to evaluate the full nature and the extent of the contamination. This effort is scheduled to be completed in 1992, and the remedies to be used for the cleanup will be selected that same year. Because the three large landfills are located adjacent to each other, it is currently impossible to determine which one is responsible for contaminating the groundwater. Site Facts: The EPA and the County have signed a Consent Decree with the Hillsborough County Utilities Department. The decree requires the County to install a public water supply to residences with contaminated well water. It also requires the County to carry out a 30-year groundwater monitoring program for the entire landfill. The EPA is completing its search for parties potentially responsible for the contamination of the site. Based on the results of this search, the EPA will begin negotiations with the potentially responsible parties to conduct a study of the nature and extent of contamination. Environmental Progress The County's actions to cap and control the methane gas accumulation at the Taylor Road Landfill have significantly reduced the threat of exposure to contaminants while the site is undergoing further investigations into the source of the contamination and the best technologies for permanent cleanup. 88 ------- TOWER CHI COMPANY FLORIDA EPA ID# FLD004065546 REGION 4 CONGRESSIONAL DIST. 06 Lake County Clermont, 15 miles west of Orlando Site Description The 30-acre Tower Chemical Company (TCC) site is an abandoned chemical manufacturing facility. During its operation, TCC owned and used two separate parcels of land; a main facility and an irrigation field. From 1957 to 1981, TCC manufactured, produced, and stored various pesticides. TCC discharged ac/ofcwastewaters produced in the main facility into a 1/2-acre, unlined perco/at/bn/evaporation pond where contaminants were solidified:- TCC'burned and buried the wastes'on a 1 1/2-acre plot located at the main facility. In 1980, the wastewater pond at the main facility • overflowed into an adjacent swamp and entered an unnamed stream north of the site. The acidic wastewater migrated into Gourd Neck of Lake Apopka, where vegetation and aquatic animals were affected. After two court orders, TCC stopped all discharges into the pond. High levels of DDT and associated chemicals were detected at the main facility and low fish populations were noticed in the unnamed stream off site. The land of the former TCC plant was purchased by a group of real,estate investors who later resold it in 1981 to local farmers and various small manufacturing firms. Approximately 1,000 people live near the site! The site is located in an area of mixed agricultural, • residential, and industrial uses! ' ; >! < • --, Site Responsibility: This site is being addressed through Federal actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 L\ Threats and Contaminants Copper and pesticides, including DDT, have contaminated on-site surface and subsurface soils, the shallow groundwater, and surface waters. Pesticides also contaminate on-site and off-site sediments. Volatile organic compounds (VOCs) including ethylbenzene are present in on-site soils. Potential health threats include accidentally swallowing and touching contaminated surface water, groundwater, and soil. The main concern is that contaminants in the shallow aquifer may move into the deeper Floridian Aquifer, which is the only source of drinking water to people in this area. March 1990 NPL HAZARDOUS WASTE SITES 89 continued ------- TOWER CHEMICAL COMPANY Cleanup Approach This site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of the entire site. Response Action Status Immediate Actions: In 1983, 2,275-square-feet of contaminated soil, 1,545 cubic yards of sediment, and 72 drums were excavated and disposed of off site. In addition, a million gallons of wastewater were pumped from the pond, treated, and then discharged to the unnamed stream. The EPA used clean fill to replace soil which was removed. The EPA built a system to divert surface water runoff and also fenced the area. These actions were conducted to prevent contaminants in the wastewater pond, on-site soil, and sediments from further migrating off site. Entire Site: The EPA's initial remedies for cleanup of the site include: (1) removing and treating on site approximately 100,000,000 gallons of contaminated groundwater, storing it temporarily on site, followed by discharge to surface water; (2) providing individual treatment units for two private wells within the immediate site vicinity; (3) excavating and burning approximately 9,000 cubic yards of contaminated surface soil from both the overflow area and portions of the burn/burial area of the site; (4) removing any drums that should have been excavated during the previous removal activities, if any are found; (5) decontaminating the two storage tanks and nearby concrete pads; and (6) diverting contaminated runoff. In 1987, the design for the water treatment system for the former percolation/evacuation pond was started. The design is planned for completion in 1990. Also, additional groundwater monitoring wells will be installed. Site Facts: In 1983, the EPA issued an order to Tower Chemical Company to clean up the site. The EPA began cleanup activities at the site because the company did not respond. Environmental Progress The removal and treatment of contaminated groundwater and soil have greatly reduced the potential for exposure to and the further spread of hazardous materials at the Tower Chemical Company site while further cleanup activities take place. 90 ------- TRI-CITY OIL CONSERVATI CORP. FLORIDA EPA ID# FLD070864541 REGION 4 CONGRESSIONAL DIST. 07 Hillsborough County Temple Terrace, near Tampa Site Description The Tri-City Oil Conservationist Corporation property, occupying about 1/4 of an acre, housed a heating oil business from 1960 to 1975. From 1978 to 1983, the facility acted as a waste oil and distribution center. Three aboveground storage tanks and one known underground storage tank were on site. While it operated, people complained to the State about the odor and sloppy practices at the site. In 1982, 3,000 gallons of oil were spilled. When the owner failed to clean up the site at the request of the Florida Department of Environmental Regulation (FDER), the EPA removed the bulk of the oil and later removed contaminated soil. Tri-City was involuntarily dissolved in 1983 and the owners are in bankruptcy. An estimated 35 people are served by 9 private wells and live within a block of the site. The site is about 3,000 feet from the Hillsborough River and within 3 miles of the public well field serving the community's 16,000 residents. Site Responsibility: This site was addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 09/01/83 Final Date: 09/01/84 Deletion Date: 01/19/88 Threats and Contaminants Elevated levels of lead were found in initial sampling of the groundwater, but none were found in later samples. Soil excavated from the area was heavily contaminated with volatile organic compounds (VOCs) and heavy metals from former site activities. Removal of contaminated soils and sludges in 1984, and again in 1986, has adequately protected human health. March 1990 NPL HAZARDOUS WASTE SITES 91 continued ------- TRI-CITY OIL CONSERVATIONIST CORP. Cleanup Approach The site was addressed in two stages: focusing on cleanup of the entire site. initial actions and a long-term remedial phase Response Action Status Initial Actions: The EPA cleaned up the 3,000-gallon oil spill in 1984 and excavated 850 cubic yards of contaminated soil and sludges, which were disposed of off-site. The excavated areas were brought, back to their original grade using clean fill, and the EPA planted grass to prevent erosion. Tests of soil, groundwater, and sediment in 1986 snowed that the source of contamination was removed. Entire Site: After detailed site analyses, the EPA.chose to perform.no further action at the site since current contaminant levels do not exceed State or Federal drinking water standards, EPA deleted the site from the NPLin1988. ,,.-,: Site Facts: The EPA issued an Administrative Order to the parties potentially responsible for contamination at the site in 1984, informing them that their activities represented an imminent and substantial danger to public health and the environment, and that they must promptly stop these activities. The EPA is negotiating with the steering committee that represents the 30 potentially responsible parties. Settlement is expected during 1990. , Environmental Progress The removal of contaminated soil and sludge from the site has restored the site to the environmental standards established by the State and the EPA, therefore no further cleanup actions were necessary at the site. The completed actions have protected the public health and the environment. The Tri-City Oil Conservationist Corp. site has been deleted from the NPL. . .. 92 ------- VARSOL SPILL FLORIDA EPA ID# FLD980602346 REGION 4 CONGRESSIONAL DIST. 18 Dade County Miami International Airport Alias: Biscayne Aquifer Site Site Description The Varsol Spill Site is located under a portion of the Miami International Airport. This site and two others, the Miami Drum Services site and the Northwest 58th Street Landfill, are being collectively considered as one management unit for the cleanup investigation and selection of cleanup activities. They are related in that they all lie on the Biscayne Aquifer, which is the sole source of drinking water for the residents of southeast Florida. Since 1966, there have been approximately 15 spills and leaks at the site totaling 2 million gallons. This included an underground pipeline leak resulting in the discharge of about 1,600,000 gallons of a petroleum solvent at the Miami International Airport. An investigative study determined in 1985 that there was no trace of the solvent at or around the airport. Several factors probably contributed to the dissipation of the contaminants in the aquifer: some of the solvent was recovered; biodegredation is believed to have taken place; and the hydrology of the area indicates that some of the solvent contributed to and became part of the "background" contamination in the aquifer. The area surrounding the site is highly populated, with 10,000 people living within 3 miles. The Miami Springs Well Field, which provides drinking water for a significant portion of Dade County, is located 2,000 feet from the walls of the airport. Site Responsibility: This site was addressed through Federal actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Deletion Date: 09/01/88 Threats and Contaminants The surface water and groundwater were contaminated with polycydic aromatic hydrocarbons (PAHs). The Varsol site is not a public health concern, as the contaminant from the spill can no longer be identified in the groundwater. March 1990 NPL HAZARDOUS WASTE SITES 93 continued ------- VARSOL SPILL SITE Cleanup Approach This site was addressed in a long-term remedial phase focusing on cleanup of the entire site. Response Action Status Entire Site: After detailed site analyses, the EPA signed a decision in 1985 mandating that no action needed to take place at this site because the Varsol site, itself, was not a public or environmental threat. The site was deleted fromtheNPLin1988. Site Facts: Dade County brought enforcement action against Eastern Airlines, the owner of the solvents that spilled. A Consent Agreement was signed to assess and clean up, if necessary, several maintenance areas and tank farms. Environmental Progress No actions were needed at the Varsol Spill Site, as contaminants that were spilled at the site were no longer detected in the area. Therefore, the possibility of exposure to hazardous substances at the site is no longer a concern. The EPA performed final investigations and deleted the site from the NPL in 1988. 94 ------- WHITEHOUSE WASTE OIL PITS FLORIDA EPA ID# FLD980602767 REGION 4 CONGRESSIONAL DIST. 03 Duval County 10 miles south of Jacksonville Site Description The Whitehouse Waste Oil Pits site occupies approximately 7 acres of an upland area immediately adjacent to a cypress swamp. The site itself consists of seven unlined pits, constructed by Allied Petroleum, where waste oil sludge, acid, and contaminated ,. waste oil from an oil reclaiming process were disposed. The first pits were constructed in 1958, and, by 1986, the company had constructed and filled the pits with approximately 127,000 cubic yards of waste. Allied Petroleum then went bankrupt. After assuming ownership of the property by tax default, the City of Jacksonville installed and operated a treatment and dewatering system at the oil pits. In 1976, the dike around one of the pits ruptured, spilling 200,000 gallons of wastes ihtb wetlands along McGirts Creek. The pit was backfilled'after the incident, A second pit released• its contents in 1976. Contamination has been detected in all of the zones of the surficial aquifer. The site is located near the Whitehouse community, which has a population of approximately 6,000 people. Most of the residents use private wells for their drinking water source. Site Responsibility: This site is being addressed through Federal actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 Threats and Contaminants The groundwater is contaminated with various heavy metals and volatile organic compounds (VOCs), including benzene, from the wastes disposed of at the site. The soil is contaminated with lead, and arsenic has been found in the leachate. Accidental releases of wastes have contaminated the nearby wetlands areas. Residents in the area could possibly be exposed to contaminated groundwater; however, at present, little contamination has been detected. March 1990 NPL HAZARDOUS WASTE SITES 95 continued ------- WHITEHOUSE WASTE OIL PITS Cleanup Approach This site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of the entire site. Response Action Status Immediate Actions: The EPA conducted several initial cleanup actions in 1986 to stabilize site conditions and prevent the spread of contamination. A water treatment system was developed and activated to drain the contaminated liquids from the pits. After the pits were drained, they were filled with construction debris, scrap lumber, trees, wood chips, and other non-degradable wastes to stabilize the pits. A 3-inch layer of automobile shredder waste was placed over the fill and a mixture of dirt and oil was placed over the shredder waste as a sealer. It was then covered with 12 inches of sand and planted with local grasses. Ditches were constructed to control runoff. Final monitoring of the test wells and drainage effluents showed remaining low levels of chlorinated organics, heavy metals, and acids. Entire Site: Based on an inspection of the site by the State of Florida, the EPA has selected several cleanup activities including: construction of a slurry wall around the entire site to prevent migration of contaminants; recovery, treatment, and removal of contaminated groundwater; removal of the contaminated sediments from the northeast tributary of McGirts Creek; and capp/ngthe entire site. A treatabil'ity study to determine the effectiveness of the selected remedies for site cleanup has been started. Preliminary results have indicated that some preferable cleanup alternatives may exist, including bioremediation. A final remedy will be chosen once these studies are completed. Environmental Progress The treatment and stabilization of wastes have greatly reduced the potential for exposure to hazardous substances at the Whitehouse Waste Oil Pits site while further investigations and cleanup activities are being completed. 96 ------- WILSON CONCE* OF FLORIDA FLORIDA EPA ID# FLD041184383 REGION 4 CONGRESSIONAL DIST. 14 Broward County Pompano Beach Site Description Wilson Concepts of Florida is a 2-acre site that is located in an industrial area of Pompano Beach. This site is an active plant that has been manufacturing precision- machine parts since 1974. The types of activities performed here include drilling and milling of metal parts, along with vibrating, deburring, degreasing, steam cleaning, and spray coating of parts. On several occasions Wilson has been cited by the County for violations of County regulations pertaining to the discharge of industrial wastes onto the ground and the overflow of wastes from two 1,200-gallon underground tanks into a storm drain and which eventually also dripped onto the ground. In 1986, the EPA discovered contamination on the ground and in a water sample from the storm drain. An investigation in 1987 found that Wilson was in violation of operating a hazardous materials facility without a license. The Wilson Concepts site is located adjacent to Chemform, Inc., another NPL site. Approximately 93,000 people depend on drinking water from at least 4 municipal wells field located within 3 miles of the site. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. NPL LISTING HISTORY Proposed Date: 06/24/88 Final Date: 03/31/89 Threats and Contaminants On-site groundwater and surface water located in the storm drain are contaminated with volatile organic compounds (VOCs) from the site spills and overflows. On-site soils located near the storm drain are contaminated with heavy metals and VOCs. The Biscayne Aquifer, a water-bearing rock foundation, underlies the site. It is a sole source of drinking water for all the residents in Broward County. Numerous cavities in the quartz sand that overlies the limestone of this rock foundation facilitate the movement of contaminants into the groundwater as well as the movement of contaminated groundwater into drinking supplies. Should the Biscayne Aquifer become contaminated, area residents using this resource would be at risk. March 1990 NPL HAZARDOUS WASTE SITES 97 continued ------- WILSON CONCEPTS OF FLORIDA Cleanup Approach This site is being addressed in a single long-term remedial phase focusing on soil and groundwater cleanup. Response Action Status Soil and Groundwater: The parties potentially responsible for site contamination will conduct investigations into the type and extent of contaminated soils and groundwater at the site and identify alternative cleanup actions. The work plan for the study is currently under review by the EPA and the field work for the study is slated to begin in 1990. Site Facts: The EPA sent Notice Letters to the parties potentially responsible for contaminating the site in 1989, requesting that these parties accept responsibility for conducting an Investigation of site contamination and cleanup methods. Later that year, the EPA and two potentially responsible parties signed an Administrative Order on Consentlo conduct the investigative study. One of the potentially responsible parties, CenTrust Bank, has been taken over by Federal regulators and is now administered by the Resolution Trust. So far, this takeover has slowed the process for cleaning the site, and the regulators have indicated that they will not comply with the Administrative Order. Therefore, the EPA may need to take over responsibility for cleaning the site. It is anticipated that the studies for the two adjacent sites, Wilson and Chem-Form, will take place concurrently. Environmental Progress After adding this site to the NPL, the EPA performed preliminary investigations and determined that there were no immediate threats to the surrounding community while further investigations and cleanup activities take place at the Wilson Concepts site. 98 ------- WINGATE RD. MUNICIPAL INCINERATOR » FLORIDA EPA ID# FLD981021470 REGION 4 CONGRESSIONAL DIST. 15 Broward County Fort Lauderdale Site Description The Wingate Road Municipal Incinerator Dump covers 61 acres in Fort Lauderdale. The site includes an incinerator, offices, and a 40-acre disposal area, all owned and operated by the City of Fort Lauderdale. The incinerator and disposal areas were used from 1955 to 1978. Residential wastes, commercial wastes, and incinerator residue were disposed of at the dump. The facility received 480 tons of waste a day and operated 7 days a week. Cooling water was pumped into the incinerator from on-site wells and then discharged into an unlined lagoon in the southeast corner of the facility. Ash residues mixed with sludge material from the lagoon were spread onto the ground in the disposal area. According to a resident of the area, hazardous waste may have been dumped on the site. In 1981, a resident reported to the Broward County Health Department that 100 steel drums had been buried from 1955 to 1958 on a dirt road. The EPA conducted tests in 1985 in the area and found pesticides in the surface and subsurface soil in the dump area. Approximately 44,000 people reside within 1 mile of the site, and an estimated 353,000 people draw drinking water from 4 municipal well fields within 3 miles of the site. Land use in the area is a combination of residential, commercial, and industrial. Site Responsibility: This site is being addressed through Federal actions. IMPL LISTING HISTORY Proposed Date: 06/24/88 Final Date: 10/04/89 IA Threats and Contaminants The soil and subsurface soil are contaminated with pesticides including DDT, aldrin, and chlordane from former waste disposal practices at the site. Direct contact with or accidental ingestion of the contaminated soil from the area of the hazardous substances could pose a potential health threat. The site is only partially fenced, making it possible for people and animals to come into direct contact with hazardous substances. Elevated pesticide concentrations were also reported in sediments from Rock Pit Lake, which is used for recreational activities. The lake intersects the Biscayne Aquifer, presenting a threat of contaminants entering the drinking water supply. March 1990 NPL HAZARDOUS WASTE SITES 99 continued ------- WINGATE RD. MUNICIPAL INCINERATOR DUMP Cleanup Approach The site is being addressed in a single long-term remedial phase directed at cleanup of the entire site. Response Action Status Entire Site: In preparation for initiating site cleanup activities, the EPA is currently conducting a search for potentially responsible parties that have contributed to site contamination. The EPA expects to begin a comprehensive investigation in 1990 of site activities and will study various cleanup strategies. Once the study is completed, a final remedy selection will be made. Environmental Progress After placing the Wingate Road Municipal Incinerator Dump site on the NPL, the EPA determined that the site does not pose an immediate threat to public health or the environment while the site is undergoing intensive investigations into permanent cleanup strategies. 100 ------- WOODBURY CHEMICAL CO FLORIDA EPA ID# FLD004146346 Site Description REGION 4 CONGRESSIONAL DIST. 19 Bade County 1/2 mile southwest of Princeton Since 1975, the 3-acre Woodbury Chemical Company has blended technical-grade materials in 50-gallon vats to produce pesticides and fertilizers. The site consists of six buildings including an office, warehouses, and production buildings, as well as several aboveground storage tanks, the majority of which are diked. Most of the facility grounds are paved. In 1986, the EPA identified various pesticides in four surface soil samples from the site. An estimated 17,600 people live within 3 miles of the site. These residents depend on the Biscayne Aquifer underlying the site for their drinking water. The EPA has designated the aquifer as the sole source of drinking water for Dade County. Three well fields and several private wells are within 3 miles of the site and one private well is 570 feet from the site. A canal that flows into Biscayne Bay is ' approximately 2,350 feet northeast of the site. Site Responsibility: This site is being addressed through Federal actions. IMPL LISTING HISTORY Proposed Date: 06/24/88 Threats and Contaminants The soil is contaminated with pesticides, including aldrin, dieldrin, and chlordane from former site operations. Direct contact with the contaminated soil may be a possible health threat. According to the Florida Marine Patrol, manatees, which are designated as an endangered species by the U.S. Fish and Wildlife Service, are frequently seen near the site. March 1990 NPL HAZARDOUS WASTE SITES 181 continued ------- WOODBURY CHEMICAL COMPANY Cleanup Approach This site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of the entire site. Response Action Status Immediate Actions: The removal of contaminated soil by the parties potentially responsible for site contamination began in 1990. The soil is being taken to an off-site facility for proper disposal. Entire Site: Negotiations have begun with the parties potentially responsible for site contamination to conduct a study to determine the full extent of contamination and to identify potential cleanup activities. Cleanup , _ „ activities will begin soon after completion of these negotiations and investigations. Site Facts: Notice Letters were sent in 1990 to the parties potentially responsible for the contamination of the site. Environmental Progress The removal of contaminated soil has greatly reduced the potential for exposure to hazardous materials at the Woodbury Chemical Company site and reduced the potential for spread of contaminants. These actions have helped to protect the public and the environment while further investigations take place. 102 ------- YELLOW WAT ROAD DUMP FLORIDA EPA ID# FLD980844179 REGION 4 CONGRESSIONAL DIST, 03 Duval County 1 mile south of Baldwin Alias: American Environmental Energy Co. Site Description Prior to commercial development, the 14-acre Yellow Water Road Dump site was part of a dairy farm. The site was purchased in the late 1940s; however, it was not until 1981, with the formation of American Environmental Energy Corporation (AEEC), that the site was developed for commercial uses. The AEEC was formed on the premise that insulation fluids contaminated with polychlorinated biphenyls (PCBs) could be removed from transformers and the transformers could then be salvaged. AEEC planned, through a joint venture with American Electric Corporation (AEC), to dispose of the RGB-contaminated fluids in an 6n-site incinerator. From 1981 to 1984, transformers, tanks, and drums filled with PCBs, waste oils, and solvents were transported to the site for disposal. Incineration of PCBs never occurred, as neither AEEC nor AEC were issued permits to conduct on-site incineration. The operation ended when the property was rezoned. By that time, approximately 63,000 gallons of oil and transformer fluid containing PCBs had leaked from containers, drums, and tanks, according to the EPA. Two residences with private wells are located on the Yellow Water Road site property. A trailer park with 100 residents using private wells is located approximately 1/4 mile east of the site. Site Responsibility: This site is being addressed through Federal and potentially responsible parties' actions. IMPL LISTING HISTORY Proposed Date: 09/01/85 Final Date: 06/01/86 IV Threats and Contaminants PCBs, iron, and lead from former site operations have been found in the groundwater both on and off site. PCBs, hexachlorobenzene and arochlor were detected in the soil samples taken from the site. Accidental ingestion of contaminated groundwater and direct contact with contaminated soil and groundwater may pose health threats. An unnamed recreational pond 2,000 feet north of the site is also threatened by contamination migrating from the site. March 1990 NPL HAZARDOUS WASTE SITES 103 continued ------- YELLOW WATER ROAD DUMP Cleanup Approach The site is being addressed in two stages: immediate actions and a long-term remedial phase focusing on cleanup of soil and groundwater. Response Action Status Immediate Actions: In 1984, the EPA removed drums from the site, empty drums were crushed, and full drums were staged for sampling. tanks and a nearby pond were sampled. Transformers were sampled, Six opened, decontaminated, and removed from the site; the contaminated soil from the area was excavated. In 1985, a water treatment system was set up for the water used in the cleanup and for the water in the pond. After the cleanup was completed, the site was closed and public access was denied. Soil and Groundwater: The parties potentially responsible for the contamination are currently conducting an investigation of the site to determine if groundwater and soil contamination have been eliminated by previous cleanup actions. The study, expected to be completed in 1990, will describe any remaining contamination at the site, and recommendations for final site cleanup methods will be made. Site Facts: In 1985, the EPA secured a court order that prevented the owner of the site from removing transformers from the site without the EPA's approval. The source of contamination is still under question because, in 1980, a truck accident resulted in a PCB/oil spill on the road near the site. Environmental Progress The immediate actions taken to remove contaminated drums and to decommission transformers on the site have significantly reduced the potential for exposure to hazardous materials at the Yellow Water Road Dump site while the investigation into a permanent cleanup solution is taking place. 104 ------- ZELLWOOD GROUNDWAT CONTAMINAT FLORIDA EPA ID# FLD049985302 REGION 4 CONGRESSIONAL DIST. 05 Orange County 1/2 mile west of the Town of Zellwood Alias: Drum Service Company of Florida Site Description The Zellwood Groundwater Contamination site covers 57 acres near Zellwood and is occupied by four industries. Between 1963 and 1971, Drum Service Company of Florida, a drum recycling facility, operated a wastewater disposal system without a regulatory permit, treating and disposing of wastewater in two unlined on-site ponds. In 1980, the company eliminated the use of these ponds and drained and removed contaminated sediments from them. Douglas Fertilizer and Chemical Company and Southern Liquid Fertilizer discharged wastewater from their production process into three unlined lagoons. Additionally, from 1960 to 1983, the Zellwin Farms Company facility, a vegetable washing and packing plant, discharged wastewater from the vegetable washing process into a ditch. Approximately 300 homes are located within a 1-mile radius of the site and depend on private wells as their sole source of drinking water. The Town of Zellwood is 1/2 mile away, and about 5,000 of its residents use groundwater for drinking water. A portion of the site is a marshy wetland. Site Responsibility: This site is being addressed through Federal and potentially responsible parties'actions. NPL LISTING HISTORY Proposed Date: 10/01/81 Final Date: 09/01/83 L\ Threats and Contaminants The groundwater, sediments, soil, and sludges are contaminated with organics including polycyclic aromatic hydrocarbons (PAHs), pesticides, and heavy metals including arsenic, cadmium, chromium, and lead from former waste disposal practices at the site. People who use contaminated groundwater as their source of drinking water may be at risk. Those who touch or accidentally ingest contaminated soil, sludges, or sediments may be harmed. If contaminants have leached from the lagoon areas into the on-site wetland, wildlife may be adversely affected. March 1990 NPL HAZARDOUS WASTE SITES 105 continued ------- ZELLWOOD GROUNDWATER CONTAMINATION Cleanup Approach This site is being addressed in three stages: an immediate action and two long-term remedial phases focusing on soil cleanup and groundwater cleanup. Response Action Status Immediate Action: During an EPA inspection in 1982, an abandoned drum area was discovered. Under EPA supervision, the party potentially responsible for the drums, NAPA Properties, paid for their removal. Soil and Groundwater: In 1987, the EPA selected two remedies to clean up soil and groundwater which include: excavating the soils and sediments and incinerating them on site; testing the residuals from incineration to determine the appropriate method to dispose of them; pumping the water and treating it; and flushing the treated groundwater back through the abandoned drum area to clean up residual contamination. After these actions, long- term groundwater monitoring for private drinking wells will be conducted. The EPA is preparing the technical data and design for cleaning up the groundwater. Once the design phase is finished in 1991, cleanup activities will begin. Environmental Progress The removal of drums has eliminated immediate threats to the public at the Zellwood Groundwater Contamination site while further cleanup activities continue. 106 ------- 62ND STREET DUMP FLORIDA EPA ID# FLD980728877 REGION 4 CONGRESSIONAL DIST. 07 Hillsborough County Tampa Site Description The 62nd Street Dump is a 5-acre abandoned industrial waste dump in Tampa. The site originally was used to mine sand. The areas excavated for sand were subsequently used by several companies to dispose of various waste materials including shredded automobile parts, batteries, waste cement, kiln dust, and kiln liners. The site came to the attention of the Hillsborough County Environmental Protection Commission in 1976, when several fish kills occurred in the Peninsular Fisheries breeding ponds on the western side of the dump. The site has been closed since 1976, but unauthorized dumping of household garbage persisted for several years after the site closed. A fence around the property presently prevents dumping. The site is located in the East Lake/Orient Park neighborhood, which has a population of approximately 5,500 people. The residents in the vicinity of the site use wells drawing on the Floridian Aquifer tor their water supply. An 80-acre marshland that drains into a nearby lake is located adjacent to the fish farm. Site Responsibility: This site is being addressed through Federal and State actions. NPL LISTING HISTORY Proposed Date: 12/01/82 Final Date: 09/01/83 Threats and Contaminants Groundwater is contaminated with heavy metals including arsenic and lead from former waste disposal activities. Soil is contaminated with heavy metals such as barium and lead, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). During heavy rain, water tends to accumulate in portions of the site, and the runoff may spread contaminants in the soil and sediments to other areas. People may be at risk from touching or accidentally ingesting the contaminated groundwater or soil. March 1990 NPL HAZARDOUS WASTE SITES 107 continued ------- 62ND STREET DUMP Cleanup Approach The site is being addressed in a single long-term remedial phase focusing on cleanup of the entire site. Response Action Status Entire Site: The State of Florida is investigating the extent of contamination at the site. In addition, various alternatives for cleaning the groundwater will be examined. This investigation is slated for completion in 1990. The proposed remedy for the 62nd Street Dump site involves solidifying and stabilizing shredded auto parts and battery wastes and capping the entire landfill. Groundwater in the shallow aquifer exceeding the drinking water standards for lead and chromium will be recovered and treated, with discharge to either a local wastewater treatment plant or to the Palm River. Environmental Progress After adding the 62nd Street Dump site to the NPL, the EPA determined that the site does not currently pose an immediate threat to the public or the environment while investigations are being conducted to determine the best cleanup technologies for a permanent remedy for the site contamination. 108 ------- f\ % his glossary defines the italicized terms used in the "|,- x - site fact sheets for the State of Florida. The terms and abbreviations contained in this glossary are often defined in the context of hazardous waste management as described in the site fact sheets, and apply specifically to work performed under the Superfund program. Thus, these terms may have other meanings when used in a different context. Acids: Substances, characterized by low pH (less than 7.0) that are used in chemical manufacturing. Acids in high concentration can be very corrosive and react with many inorganic and organic substances. These reactions may possibly create toxic compounds or release heavy metal contaminants that remain in the environment long after the acid is neutralized. Administrative Order On Consent: A legal and enforceable agreement between EPA and the parries potentially responsible for site contamination. Under the terms of the Order, the potentially responsible parties agree to perform or pay for site studies or cleanups. It also describes the oversight rules, responsibilities and enforcement options that the government may exercise in the event of non-compliance by potentially respon- sible parties. This Order is signed by PRPs and the government; it does not require approval by a judge. Administrative Order [Unilateral]: A legally binding document issued by EPA direct- ing the parties potentially responsible to perform site cleanups or studies (generally, EPA does not issue unilateral orders for site studies). Aeration: A process that promotes breakdown of contaminants in soil or water by exposing them to air.

Carbon Adsorption: A treatment system in which contaminants are removed from groundwater and surface water by forcing water through tanks containing activated G-2 ------- carbon, a specially treated material that attracts and holds or retains contaminants. Carbon Disulfide: A degreasing agent formerly used extensively for parts washing. This compound has both inorganic and organic properties, which increase cleaning efficiency. However, these properties also cause chemical reactions that increase its hazard to human health and the environment. Carbon Treatment: [see Carbon Adsorption]. Cell: In solid waste disposal, one of a series of holes in a landfill where waste is dumped, compacted, and covered with layers of dirt. Chromated Copper Arsenate: An insecticide/herbicide formed from salts of three toxic metals: copper, chromium, and arsenic. This salt is used extensively as a wood pre- servative in pressure-treating operations. It is highly toxic and water soluble, making it a relatively mobile contaminant in the environment. Closure: The process by which a landfill stops accepting wastes and is shut down under Federal guidelines that ensure the public and the environment is protected. Confluence: The place where two bodies of water, such as streams, come together. Consent Decree: A legal document, approved and issued by a judge, formalizing an agreement between EPA and the parties potentially responsible for site contamination. The decree describes cleanup actions that the potentially responsible parties are re- quired to perform and/or the costs incurred by the government that the parties will reimburse, as well as the roles, responsibilities, and enforcement options that the gov- ernment may exercise in the event of non-compliance by potentially responsible parties. If a settlement between EPA and a potentially responsible party includes cleanup ac- tions, it must be in the form of a consent decree. A consent decree is subject to a public comment period. Consent Order: [see Administrative Order on Consent]. Containment: The process of enclosing or containing hazardous substances in a struc- ture, typically in ponds and lagoons, to prevent the migration of contaminants into the environment. Cooperative Agreement: A contract between EPA and the states wherein a State agrees to manage or monitor certain site cleanup responsibilities and other activities on a cost- sharing basis. G-3 ------- Creosotes: Chemicals used in wood preserving operations and produced by distillation of tar, including polycydic aromatic hydrocarbons and polynudear aromatic hydrocar- bons [see PAHs and PNAs]. Contaminating sediments, soils, and surface water, creo- sotes may cause skin ulcerations and cancer with prolonged exposure. Culvert A pipe under a road, railroad track, path, or through an embankment used for drainage. De minimis: This legal phrase pertains to settlements with parties who contributed small amounts of hazardous waste at a site. This process allows EPA to settle with small, or de minimis contributors, as a single group rather than as individuals, saving time, money, and effort.

Leach, Leaching [v.t.]: The process by which soluble chemical components are dissolved and carried through soil by water or some other percolating liquid. Long-term Remedial Phase: Distinct, often incremental, steps that are taken to solve site pollution problems. Depending on the complexity, site cleanup activities can be separated into a number of these phases. Migration: The movement of oil, gas, contaminants, water, or other liquids through porous and permeable rock. Mine (or Mill) Tailings: A fine, sandy residue left from ore milling operations. Tail- ings often contain high concentrations of lead and arsenic or other heavy metals. Mitigation: Actions taken to improve site conditions by limiting, reducing, or control- ling toxicity and contamination sources.

Naphthalene, pyrene, and trichlorobenzene are examples of neutrals. Nitroaromatics: Common component of explosive materials, which will explode if activated by very high temperatures or pressures; 2,4,6-Trinitrotoluene (TNT) is a ni- troaromatic. Notice Letter: A General Notice Letter notifies the parties potentially responsible for site contamination of their possible liability. A Special Notice Letter begins a 60-day formal period of negotiation during which EPA is not allowed to start work at a site or initiate enforcement actions against potentially responsible parties, although EPA may undertake certain investigatory and planning activities. The 60-day period may be extended if EPA receives a good faith offer [see Good Faith Offer] within that period. G-6 ------- Outfall: The place where wastewater is discharged into receiving waters. Overpacking: Process used for isolating large volumes of waste by jacketing or encap- sulating waste to prevent further spread or leakage of contaminating materials. Leak- ing drums may be contained within oversized barrels as an interim measure prior to removal and final disposal.

It is a common component of creosotes and can cause cancer. Perched (groundwater): Groundwater separated from another underlying body of ground water by a confining layer^ often day or rock. Percolation: The downward flow or filtering of water or other liquids through subsur- face rock or soil layers, usually continuing downward to groundwater. Petrochemicals: Chemical substances produced from petroleum in refinery operations and as fuel oil residues. These include fluoranthene, chrysene, mineral spirits, and refined oils. Petrochemicals are the bases from which volatile organic compounds (VOCs), plastics, and many pesticides are made. These chemical substances are often toxic to humans and the environment. Phenols: Organic compounds that are used in plastics manufacturing and are by- products of petroleum refining, tanning, textile, dye, and resin manufacturing. Phenols are highly poisonous and can make water taste and smell bad. Plume: A body of contaminated groundwater flowing from a specific source. The movement of the groundwater is influenced by such factors as local groundwater flow patterns, the character of the aquifer in which groundwater is contained, and the den- sity of contaminants. Polycyclic Aromatic Hydrocarbons or Polyaromatic Hydrocarbons (PAHs): PAHs, such as pyrene, are a group of highly reactive organic compounds found in motor oil. They are a common component of creosotes and can cause cancer. Polychlorinated Biphenyis (PCBs): A group of toxic chemicals used for a variety of purposes including electrical applications, carbonless copy paper, adhesives, hydraulic fluids, microscope emersion oils, and caulking compounds. PCBs are also produced in certain combustion processes. PCBs are extremely persistent in the environment be- cause they are very stable, non-reactive, and highly heat resistant. Burning them pro- duces even more toxins. Chronic exposure to PCBs is believed to cause liver damage. It G-7 ------- GtOSSXRY: is also known to bioaccumulate in fatty tissues. PCB use and sale was banned in 1979 with the passage of the Toxic Substances Control Act. Polynuclear Aromatic Hydrocarbons (PNAs): PNAs, such as naphthalene, and biphen- yls, are a group of highly reactive organic compounds that are a common component of creosotes, which can be carcinogenic. Polyyinyl Chloride (PVC): A plastic made from the gaseous substance vinyl chloride. PVC is used to make pipes, records, raincoats, and floor tiles. Health risks from high concentrations of vinyl chloride include liver cancer and lung cancer, as well as cancer of the lymphatic and nervous systems. Potentially Responsible Parties (PRPs): Parties, including owners, who may have contributed to the contamination at a Superfund site and may be liable for costs of response actions. Parties are considered PRPs until they admit liability or a court makes a determination of liability. This means that PRPs may sign a consent decree or admin- istrative order on consent [see Administrative Order on Consent] to participate in site cleanup activity without admitting liability. Radionudides: Elements, including radium, and uranium-235 and -238, which break down and produce radioactive substances due to their unstable atomic structure. Some are man-made and others are naturally occurring in the environment. Radon, which is the gaseous form of radium, decays to form alpha particle radiation, which can be easily blocked by skin. However, it can be inhaled, which allows alpha particles to affect unprotected tissues directly and thus cause cancer. Uranium, when split during fission in a nuclear reactor, forms more radionuclides which, when ingested, can also cause cancer. Radiation also occurs naturally through the breakdown of granite.stones. Remedial: A course of study combined with actions to correct site contamination problems through identifying the nature and extent of cleanup strategies under the Superfund program. Retention Pond: A small body of liquid used for disposing wastes and to contain overflow from production facilities. Sometimes retention ponds are used to expand the capacity of such structures as lagoons to store waste. Runoff: The discharge of water over land into surface water. It can carry pollutants from the air and land into receiving waters. Sediment: The layer of soil, sand and minerals at the bottom of surface waters, such as streams, lakes, and rivers that absorb contaminants. G-8 ------- Seeps: Specific points where releases of liquid (usually leachate) form from waste disposal areas, particularly along the lower edges of landfills. Seepage Pits: A hole, shaft, or cavity in the ground used for storage of liquids, usually in the form of leachate, from waste disposal areas. The liquid gradually leaves the pit by moving through the surrounding soil. Septage: Residue remaining in a septic tank after the treatment process. Sinkhole: A hollow depression in the land surface in which drainage collects; associ- ated with underground caves and passages that facilitate the movement of liquids. Sludge: Semi-solid residues from industrial or water treatment processes that may be contaminated with hazardous materials. Slurry Wall: Barriers used to contain the flow of contaminated groundwater or subsur- face liquids. Slurry walls are constructed by digging a trench around a contaminated area and filling the trench with an impermeable material that prevents water from passing through it. The groundwater or contaminated liquids trapped within the area surrounded by the slurry wall can be extracted and treated. Stabilization: The process of changing an active substance into inert, harmless mate- rial, or physical activities at a site that act to limit the further spread of contamination without actual reduction of toxicity. Stillbottom: Residues left over from the process of recovering spent solvents. Stripping: A process used to remove volatile contaminants from a substance [see Air Stripping]. Sumps: A pit or tank that catches liquid runoff for drainage or disposal. Surge Tanks: A holding structure used to absorb irregularities in flow of liquids, in- cluding liquid waste materials. Trichloroethylene (TCE): A stable, colorless liquid with a low boiling point. TCE has many industrial applications, including use as a solvent and as a metal degreasing agent. TCE may be toxic to people when inhaled, ingested, or through skin contact and can damage vital organs, especially the liver [see also Volatile Organic Compounds], Unilateral [Administrative] Order: [see Administrative Order on Consent]. G-9 ------- GLOSSARY Upgradient: An upward slope; demarks areas that are higher than contaminated areas and, therefore, are not prone to contamination by the movement of polluted groundwa- ter. Upslope: Upstream; often used relative to groundwater [see Upgradient]. Vegetated Soil Cap: A cap constructed with graded soils and seed for vegetative growth to prevent erosion [see Cap]. Volatile Organic Compounds (VOCs): VOCs are made as secondary petrochemicals. They include light alcohols, acetone, trichloroethylene, perchloroethylene, dichloroeth- ylene, benzene, vinyl chloride, toluene, and methylene chloride. These potentially toxic chemicals are used as solvents, degreasers, paints, thinners, and fuels. Because of their volatile nature, they readily evaporate into the air, increasing the potential exposure to humans. Due to their low water solubility, environmental persistence, and widespread industrial use, they are commonly found in soil and groundwater. Watershed: The land area that drains into a stream or other water body. Wetland: An area that is regularly saturated by surface or groundwater and, under normal circumstances, capable of supporting vegetation typically adapted for life in saturated soil conditions. Wetlands are critical to sustaining many species of fish and wildlife. Wetlands generally include swamps, marshes, and bogs. Wetlands may be either coastal or inland. Coastal wetlands have salt or brackish (a mixture of salt and fresh) water, and most have tides, while inland wetlands are non-tidal and freshwater. Coastal wetlands are an integral component of estuaries. G-10 ------- |
