Contamination is primarily related to more than a century of manufacturing operations, in- cluding the production of arsenic insecticide, organic chemicals, and glue made from animal hides. Waste products from these operations were disposed of randomly over the years. The major environmental concerns in- volve soils and sludges that are contaminated with heavy metals, animal glue wastes that emit odors, and two discrete ground water plumes that contain vola- tile organics. One ground water plum is contaminated with ben- zene and the other with toluene. Soils at the site are contaminated with high levels of arsenic, chromium, and lead. Air emis- sions from an animal-hide dis- posal pile contain high levels of hydrogen sulfide. Decision: • Grade, cap, and implement insti- tutional controls for areas con- taining contaminated soils and sediments. • Pump and treat hot spot areas of ground water contamination as an interim remedy. Treat ground water through the use of air strip- ping and implement ground wa- ter monitoring system. • Stabilize side slopes of hide pile; cap with a synthetic liner; and in- stall a gas collection layer and ac- tivated carbon or thermal oxida- tion treatment system. Contacts: • Region: Rich Leighton FTS 835-1461 • Headquarters: Candice Cable FTS 475-7028 PRICE LANDFILL REGION II NEW JERSEY (Approved 9/29/86) Description: • This 26-acre site was originally a sand and gravel operation. In 1969, the facility became a com- mercial solid waste landfill, and in 1971, it began to accept both drummed and bulk liquid wastes. It has been estimated that 9.1 million gallons of chemical wastes were disposed of at the site. In 1980, residential wells in the area were found to be con- taminated with volatile organic compounds. As an interim mea- sure, potable water was provided to affected residents. An RI/FS was conducted at the site from January 1982 through May 1983, and in September 1983, a ROD was signed addressing reloca- tion and replacement of the af- fected well field. Total volatile or- ganic concentrations range from 40 to 50 ppm at shallow depths in the aquifer. Decision: • Install a security fence around the landfill site. • Install ground water extraction wells to control the source of the contamination and abate the con- taminant plume. • Construct a ground water/ leachate pretreatment facility to treat extracted ground water and leachate prior to discharge to the county sewer system. • Monitor ground water for approxi- mately 25 years. • Construct a landfill cap at the conclusion of the ground water extraction process. Contacts: • Region: Bob McKnight FTS 264-7509 • Headquarters: Lisa Feldt FTS 475-8246 ROCKAWAY BOROUGH WELL FIELD REGION II NEW JERSEY (Approved 9/29/86) Description: • This site consists of three mu- nicipal supply wells screened in a glacial aquifer that is the sole drinking water source for approxi- mately 11,000 people. Volatile or- ganic compounds were detected in the municipal wells in 1979. Subsequent investigations iden- tified perchloroethylene and tri- chloroethylene as the primary contaminants. The local water department has been treating the water using granular activated carbon since July 1981. No sources of contamination have been identified at this time. Decision: • The Borough cannot be reim- bursed for the cost of the treat- ment unit. However, the Borough should do the following: 1. Maintain existing granular ac- tivated carbon treatment system 2. Modify operations to comply with current Safe Drinking Water Act standards 3. Consider regenerating spent carbon off site. • EPA will continue investigations to determine source(s) and extent of contamination and will evalu- ate additional remedial action alternatives to address those sources. Contacts: • Region: Alberto Barrera FTS 264-1217 • Headquarters: Lisa Feldt FTS 475-8246 SHARKEY LANDFILL REGION II NEW JERSEY (Approved 9/29/86) Description: • Landfilling operations began at this 90-acre site in 1945. In addi- tion to receiving municipal solid waste, the landfill allegedly re- ceived hazardous materials be- tween 1962 and 1969. Landfill op- erations ceased at the site in 1972. Remedial investigations at the site indicate the presence of organic and inorganic contami- nants in the surface soils and ground water. Decision: • Cap the landfill in accordance with relevant RCRA require- ments. • Install a venting system for land- fill gases. • Extract shallow ground water and leachate. • Treat contaminated ground water by discharging it to the sanitary sewer system or by air stripping. • Install surface water controls to divert run-on and run-off. • Install a security fence around the site. • Develop a monitoring plan to en- sure the effectiveness of the re- medial action.

From 1960 to 1968, the landfill accepted municipal wastes. As a result of odor and staining in a resident's well water, the county conducted a study. The results of the study showed that leachate from the landfill was contaminating the underlying aquifers. In 1980, a re- covery well network was installed to minimize migration. In addi- tion, the major downgradient user, a private water company, has reduced pumpage. The Rl de- termined that the ground water, surface water, and sediments were contaminated with metals and organics. Decision: • Install a RCRA-type cap with gas vents to minimize infiltration. • Continue to operate and monitor recovery well network. • Evaluate recovery well system for 5 years. Determine if upgradient controls are needed to intercept lateral ground water inflow. • Defer ground water treatment and sediment remedial action de- cisions. Contacts: • Region: Galena Bendersky Chadwick FTS 597-3167 • Headquarters: Patty Bubar FTS 382-4831 BLOSENSKI LANDFILL REGION III PENNSYLVANIA (Approved 9/29/86) Description: • This 13.6-acre landfill operated from the 1950s until the early 1980s. During this time, munici- pal and industrial wastes, includ- ing solvents, paints, and waste- water treatment sludges, were dumped on the surface of the site and buried in drums. A site in- spection conducted by EPA in 1982 indicated serious ground water contamination. Sub- sequent sampling as part of the Rl revealed contamination of sur- ficial and subsurface soils, ground water, and residential wells. Contaminants include a wide variety of volatile and semi- volatile compounds, metals, PAHs, and PCBs. Transport through ground water is the most significant mechanism of conta- minant migration at the site. Decision: • Install public water supply line to an estimated 12 affected resi- dences. • Excavate and remove buried drums and surrounding material and dispose of these materials at a RCRA facility. • Perform a study to determine the extent of ground water contami- nation and collect data for the de- sign of a ground water pumping and treatment system. • Install a cover over the landfill in accordance with RCRA. • Monitor ground water and sur- face water in accordance with RCRA closure regulations.

REGION IV FLORIDA (Approved 9/25/86) Description: • The site is an active 11-acre wood preserving facility that uses pen- tachlorophenol and has operated since 1954. Prior to 1970, treated effluent from the facility was dis- charged to an onsite drainage ditch. In addition, sludge from the treatment process was deposited into two unlined pits onsite. In 1980, the City of Jacksonville confirmed the presence of ground water contamination on- site. The contents of the two un- lined pits were excavated and disposed of offsite as part of an EPA removal action in 1985. The Rl, completed in April 1986, iden- tified PCP contamination in soils, surface water and sediments, and ground water. Although PCP is the primary contaminant of concern, other compounds, such as PAHs, VOCs, metals, and PCBs, have been found both on and off the site. Decision: • Excavate and incinerate, onsite, soils and sediments with PCP concentrations greater than 10 mg/kg, approximately 9,000 cubic yards. • Backfill with decontaminated soils. • Recover ground water with PCP concentrations exceeding 1 mg/l. To comply with state surface water discharge criteria, treat re- covered ground water until PCP concentration is less than 1 g/l. • Discharge treated ground water to an onsite drainage ditch. Contacts: • Region: Chris Teepin FTS 257-2643 • Headquarters: Caroline Hoover FTS 382-7997 MOWBRAY ENGINEERING COMPANY REGION IV ALABAMA (Approved 9/25/86) Description: • This site consists of a 3-acre swamp adjacent to a former elec- trical transformer repair facility. Between the mid-1950s and the mid-1970s, the facility disposed of waste transformer oil by dump- ing it onto the ground. The oil drained via a storm sewer into the adjacent swamp. It is estimated that during that 20-year period, approximately 20,000 used trans- formers were drained, each con- taining approximately 9 gallons of oil. In 1975, a major fish kill oc- curred in a stream adjacent to the site. Only trace amounts of PCBs were found in the soils, and no further action was taken. In 1980, following a second fish kill, sampling revealed PCB soil con- centrations of 500 ppm. At this time, EPA removed and disposed of the top 6 inches of conta- minated soils from the swamp. The contaminated soils were sent to an approved off-site haz- ardous waste facility. The com- bined Rl and FS was completed in July 1986. PCBs are con- sidered to be the only potentially significant contaminant at the site based on concentration, toxi- city, and frequency of detection. Decision: • Excavate, remove, and dispose of two 3,000-gallon underground storage tanks containing waste oils. • Treat or dispose of waste oils en- countered in the swamp area and in the underground storage tanks by a TSCA-approved method. • Divert surface run-on around thei contaminated swamp area to pre vent continued erosion. • Excavate soils contaminated above 25 ppm and dispose via off-site or on-site incineration or ------- stabilization/solidification. Infra- red incineration is the preferred alternative. However, if operating details for this process prove un- satisfactory, the waste will be stabilized/solidified. • Grade and revegetate the swamp area. • Close abandoned on-site well. Contacts: • Region: Meredith Anderson FTS 257-2643 • Headquarters: Caroline Hoover FTS 382-7997 SCRDI DIXIANA REGION IV SOUTH CAROLINA (Approved 9/26/86) Description: • This site consists of a warehouse on a 2-acre lot that was used to store drums. In July 1978, approx- imately 1,100 drums of industrial wastes, including paints, sol- vents, acids, oils, phenols, and dyes, were stored on site. Poor handling practices resulted in nu- merous discharges of drum con- tents into the environment. State intervention resulted in the re- moval of all surface drums and visibly contaminated soils be- tween September 1978 and June 1980. (n July 1980, sampfing re- vealed contamination of the ground water used by nearby res- idents. Subsequent investiga- tions characterized the nature and extent of contamination, which is limited to the shallow ground water. The contaminants detected in the ground water be- neath the site are predominantly volatile organic compounds along with several non-volatile organic compounds. The maxi- mum concentration of individual contaminants approached 1 ppm. There is no indication of surface water contamination, and surface soil contamination is very limited. The primary pathway of potential exposure at the site is migration of contaminants through the shallow ground water. Decision: • Extract and treat contaminated ground water, via carbon adsorp- tion and air stripping, to concen- trations equivalent to a cumu- lative risk of 10 ~B. • Discharge treated ground water to surface water (regulated by South Carolina's NPDES Dis- charge Permit) and/or discharge on site based on hydraulic capac- ity of the subject area.

During this period, waste prod- ucts from site operations were discharged into an uncontained 2-acre lagoon and wastewater ditch in a wetlands area All oper- ations at the site were terminated in 1977. Rl activities, completed at the site in August 1985, identi- fied contamination in the shallow ground water, lagoon sludge, soils and sediments, and surface water. The primary contaminants at the site are VOCs, PAHs, and lead. To date, all potentially af- fected residential wells have been found to be uncontami- nated. Decision: • Excavate, and incinerate onsite, 4,600 cubic yards of sludge and 20,500 cubic yards of contami- nated soils and sediments to achieve a 10 excess cancer risk level. • Pump and treat ground water to restore the aquifer and control contaminant migration over a 25-to 50-year period. • Extend municipal water system to replace private water supplies most likely to be affected by ground water contamination. • Abandon individual wells in ac- cordance with state codes.

In 1981, drums were un- earthed at the site, and analyses indicated the presence of several hazardous substances. A magne- tometer survey in 1982 concluded that as many as 35,000 drums were buried at the site. Soil and ground water samples taken in 1985 confirmed that these media were being contaminated by haz- ardous substances migrating from the buried drums. Although no contaminants have been de- tected in downgradient resi- dential water samples, the pri- mary health threat from the site is the consumption of potentially contaminated ground water. This ROD addresses source control at the site. An additional RI/FS, scheduled for completion in FY 1988, will address other contami- nated soils as well as ground water. Decision: • Excavate areas of the site con- taining buried drums and dispose of drums and soil at an off-site RCRA-compliant incinerator.

Creosote and waste products re- sulting from the company's pro- cess polluted the surface of the site and four underlying aquifers. Contaminants, primarily PAHs, have migrated through the casing of an on-site well, contaminating the deeper aquifers and many private and municipal water sup- plies. Over the operational life of the facility, millions of gallons of waste water were discharged to an adjacent bog, which today serves as a continuous source of contamination to the subsurface environment. In 1984, a ROD was signed for the construction of a granular activated carbon system for the City of St. Louis Park's well. In 1982-83, two wells that were contaminating lower aquifers were cleaned and recon- structed. Decision: • Pump, treat, and monitor contam- inated ground water in the under- lying aquifers. • Discharge contaminated ground water to a sanitary sewer. ------- • Further investigate the subsur- face in the vicinity of the site to implement deed restrictions for current and future land use. • Perform an additional RI/FS to determine the areal extent of con- tamination.

In addi- tion, from 1967 to 1978, paint sludges were dumped in a por- tion of the gravel pit. Contami- nants associated with the paint sludges have contaminated the surface and subsurface soils and the ground water. Hazardous substances identified at the site include VOCs, metals, and pes- ticides. A health assessment concluded that the major poten- tial exposure pathway is inges- tion of contaminated drinking water. This ROD addresses source control. A subsequent ROD will address contaminated ground water. Decision: • Excavate approximately 15,000 cubic yards of waste; separate combined material (liquid sludges, paint residues, and gar- bage) and solid paint sludges. • Incinerate in a RCRA-compliant off-site facility the approximately 5,000 cubic yards of combined material, and dispose of the ap- proximately 10,000 cubic yards of solid paint sludges in a RCRA landfill. Contacts: • Region: Tom Thomas FTS 886-1434 • Headquarters: Carol Lindsay FTS 475-6704 BAYOU SORREL REGION VI LOUISIANA (Approved 11/14/86) Description: • About 50 of the 265 acres that comprise this site were used in a waste disposal operation from 1977 to 1978. The site contained four landfills, four waste ponds, and one land farm. In 1978, as part of the site closure, these areas were covered with soil. The quantity of waste at the site was determined to be 36,400 cubic yards. During the Rl, which was completed in 1985, organic and herbicide wastes were found in pond 4 and soils. Vei^ little ground water contamination was found. The greatest threat ap- pears to be from direct contact by people intruding on the site. Decision: • Regrade site to control runoff; limit cap erosion and limit sur- face water ponding. • Cover disposal areas and consoli- dated wastes with RCRA-type cap with gas vents. • Collect and dispose of infiltrated water. • Dispose of remaining wastes at an offsite facility. • Construct slurry walls around landfills and pond 4. • Install ground water monitoring system and maintain for 30 years. • Fence site.

Pits were used for disposal, drums were buried, and liquids were land ap- plied. The surrounding area is a rapidly developing residential area. The Rl completed in 1983 on the entire site identified buried drums, wastes, soils, and sedi- ments contaminated with or- ganics in three areas — Bliss and contiguous properties, Callahan, and Rosalie properties — and soils and dust contaminated with up to 120 ppb dioxin on the Bliss and contiguous properties area only. An FFS of on-site storage of the dioxin wastes was completed in 1986. The ground water and surface water are not significant- ly contaminated, but they are po- tential migration pathways. Decision: • Excavate and store soils and ma- terials with dioxin contamination exceeding 1 ppb in a metal build- ing on site until the dioxin waste FFS is complete. • Maintain security system, runoff control, and ground water moni- toring system to ensure stability of the on-site storage area. • Excavate drums, remaining wastes, and contaminated soils and land dispose. Incinerate wastes that are not suitable for a landfill. • Dispose of nonhazardous mate- rial and debris at a sanitary land- fill.

Aban- doned wood-treating operations on the mill property are the source of ground water contami- nation that has contaminated private drinking water wells, In 1981, homeowners detected a creosote odor from their wells which prompted EPA to sample the ground water. This and sub- sequent sampling efforts indi- cated that contaminants were present in the ground water at a significant depth and over a wide area. Contaminants detected in the ground water include penta- chlorophenol, PAHs, volatile or- ganic and halogenated organic compounds, and metals. This first operable unit ROD ad- dressed public exposure to con- taminated ground water. Field studies are currently being con- ducted for additional operable units that will address aquifer restoration and source cleanup. Decision: • Connect ground water users to the existing public water system. • Pay for homeowners' water use. • Pass a local ordinance prohibit ing the installation of new wella that would produce water for human consumption or irrigation. ------- Contacts: • Region: Eric Fink FTS 585-5414 • Headquarters: Blake Velde FTS 382-7789 ROBINSON BRICK COMPANY AND DENVER & RIO WESTERN RAILROAD "ROBCO" OPERABLE UNITS IV AND V DENVER RADIUM SITE REGION VIII COLORADO (Approved 9/30/86) Description: • This ROD addresses Operable Units IV and V of the Denver Radium site; response actions have been divided into 11 opera- ble units. The National Radium Institute (NRI) operated a radium processing plant at the site in the early 1900s. The NRI plant closed around 1920. Since that time, radioactive tailings and unpro- cessed ore have been distributed and used as fill material. In 1979, EPA became aware of the former NRI plant. In April 1986, an Rl that addressed all 11 operable units and an FS that addressed Opera- ble Units IV and V were issued. Radium contamination in the soil and under site buildings is the primary concern at ROBCO. Po- tential exposure pathways include inhalation of radon gas and associated decay products, direct exposure to gamma ra- diation, and ingestion or inhala- tion of radium-contaminated materials. Decision: • Remove approximately 6,400 cub- ic yards of radium-contaminated soil and approximately 200 cubic yards of debris. • Develop a temporary on-site stor- age facility for all waste mate- rials. • Dispose of the contaminated soil and debris at a facility suitable for the permanent disposal of low- level radioactive waste after such a facility becomes available.

Wastes from the opera- tion were disposed in a pit onsite. Surface water from the site even- tually drains into a drinking water source, and the lower contami- nated aquifer is also a water source. When the site was aban- doned in 1985, 114 drums and containers were removed. The Rl completed in 1985 showed that an upper and lower aquifer, soil, and sediments were contami- nated with hexavalent chromium. Decision: • Extract ground water from both aquifers and treat on site (via chemical reduction and precipita- tion) to 0.05 mg/l chromium in the confined aquifer and 10 mg/l in the unconfined zone. Discharge to creek or POTW. • Excavate 350 tons of contami- nated soil to form percolation basins. Land dispose offsite. • Flush chromium from remaining soil through the basins.

Prompt submission allows Headquarters to produce abstracts and summaries of the decisions for technology transfer efforts such as the ROD Update. Signed RODs should be sent to the appropriate Headquarters Regional Coordinator in HSCD or OWPE. In addition to hard copies, Head- quarters is also requesting Lexitron diskettes (IBM PC also acceptable) with the complete text for the FY'86 and FY'87 RODs. The need for the diskettes stems from Headquarters' efforts to develop an online text search and retrieval capability (known as BASIS) for the RODs. The diskettes will allow rapid transfer of the text into the BASIS system. Please send your FY'86 and FY'87 ROD diskettes directly to Debby Swichkow, Headquarters ROD Co- ordinator (WH548-E, FTS-382-2453). A CALL FOR PREFERRED ALTERNATIVE DOCUMENTS As another technology transfer ini- tiative, Headquarters is requesting all preferred alternative fact sheets or documents (proposed plans, as they are described in SARA) so that these can be circulated to other Re- gions to assist in ROD planning. Preferred alternative documents should be sent to Debby Swichkow (WH548-E, FTS 382-2453) as prompt- ly as possible. ------- |
