SUPERFUND Records Of Decision Update From: Hazardous Site Control Division April 13, 1987 To: EPA Regional Offices Vol. 3, No. 2 ROD SUMMARIES AUBURN ROAD LANDFILL REGION I, NEW HAMPSHIRE (Approved 9/17/86) Description: • The site covers a total of 200 acres on which four disposal areas, comprising approxi- mately 11.8 acreas, have been documented. In addition to being used for the authorized disposal of municipal refuse, tires, and demolition debris, all four areas contain evidence of the presence of 55-gallon drums that contain industrial hazardous waste. Ground water contamination is the principal problem identified at the site. Volatiles, semi-vola- tiles, and inorganics have been measured in the ground water onsite and in water sup- ply wells serving an adjacent mobile home village. Shortly after a draft FS was com- pleted in April 1986, approxi- mately 1,900 drums were ex- cavated and are being stored onsite. Subsequent to this re- moval action, EPA decided to divide the response into oper- able units. An FS that ad- dressed the need for an alter- native water supply was com- pleted in July 1986. Decision: • Install approximately 9,000 linear feet Qf water line to tie into existing distribution system. • Sen/ice each residential water connection; perform monthly sampling and analysis of bed- rock wells adjacent to the landfill. Contacts: • Region: Chet Janowski FTS 835-3652 • Headquarters: Bob Quinn FTS 382-2350 BA1RD AND McGUIRE REGION I MASSACHUSETTS (Approved 9/30/86) Description: • A chemical mixing and batch- ing company operated on this 8-acre site from 1912 to 1983. A variety of products, includ- ing disinfectants, soaps, floor wax, and pesticides, were for- mulated during this period. Unsound disposal practices and numerous chemical re- leases over the years have se- verely contaminated the ground water, soils, surface water, and wetlands on and in the vicinity of the site. Partial removal of contaminated ma- terials, construction of a clay cap, and installation of a ground water collection/recir- culation system were accom- plished as part of an EPA re- moval action in 1983 and 1984. Buildings and tanks onsite will be removed in early April as a result of an IRM. A sec- ond removal response was ini- tiated in 1985, when dioxin was detected in surficial soils. This response included the in- stallation of fencing and the conduct of extensive sam- pling to delineate the extent of dioxin contamination. Be- cause of the heterogeneity and complexity of the hydro- geology, soils, and contami- nation at the site, 11 distinct zones were identified and ad- dressed separately in the FS. Decision: • Excavate and provide onsite thermal destruction of approx- imately 191,000 cubic yards of contaminated soil that con- tains dioxin, pesticides, coal tar, and solvents. • Extract ground water, treat at onsite treatment plant, dis- charge to aquifer. • Restore wetlands. • Provide flood protection and relocate contaminated brook. • Monitor ground water and air quality.

In ------- 1978, volatile halogenated or- ganic (VHO) contamination, primarily in the form of PCE, TCE, and DCE, was first de- tected in the ground water. In 1984, under the auspices of a Safe Drinking Water Act, R&D grant, EPA constructed and placed on line a full-scale packed-column air stripping system to treat the entire sys- tem. In 1985, an Rl was initi- ated to determine the nature and extent of contamination in the vicinity of the site. It is believed that the well field has reached a steady-state condi- tion, and VHO levels are not expected to increase in the future. Decision: • Continue operation of existing onsite packed-column air stripping system. • Construct ground water ex- traction wells, treat extracted water with an additional off- site air stripper, and reinject the treated water. (This will al- low ground water remediation to take place in 5 to 10 years instead of 25 years.) • Second phase RI/FS planned to focus on soil remediation.

Smith FTS 382-7996 CALDWELL TRUCKING REGION II NEW JERSEY (Approved 09/25/86) Description: • Septic wastes were deposited in unlined lagoons on this 12.2-acre site beginning in the late 1940s. In the mid-1950s, industrial septic systems that may have contained hazar- dous substances were pumped, and their contents were deposited at the site. Ground water contamination in the form of chlorinated hy- drocarbons first became ap- parent around 1970, and pri- vate wells 1,200 feet from the site began to show evidence of contamination in the mid-1970s. Extremely high levels of volatiles were found in 1982, and NJDEP recom- mended that public water be provided to nearby residents. Although the original site was defined broadly by EPA to in- clude other potentially conta- minated areas, a phased approach is being used that currently addresses only Cald- well. Three operable units were defined: well head treat- ment of a contaminated mu- nicipal well by use of air strip- ping; excavation and thermal treatment of contaminated soils and waste materials; and supplemental study of ground water pollution. Decision: • Excavate and treat via thermal treatment approximately 28,000 cubic yards of contami- nated soils and waste mate- rials to drive off volatile con- stituents. • Dispose of treated soils in an onsite landfill. • Restore water supply from municipal well using air strip- ping. • Provide alternative water sup- ply for residents potentially af- fected by ground water conta- mination. • Prepare RI/FS to identify and study other sources of ground water contamination.

Smith FTS 382-7996 COMBE FILL NORTH LANDFILL REGION II NEW JERSEY (Approved 9/29/86) Description: • This 65-acre site, in a marsh, operated as a municipal land- fill from 1966 until 1981. Dur- ing the active life of the land- fill, municipal, vegetative, and industrial (nonchemical) wastes and small amounts of dry sewage sludge were re- portedly accepted. A citizens' group conducted ground water sampling at the site. This sampling eventually con- tributed to the site's being added to the NPL in Decem- ber 1982. Although hazardous substances were found at the site during the Rl, the data in- dicate that concentrations are low and that there is currently no offsite migration. However, the site is covered with rocky, permeable soil, and waste is known to exist in the shallow aquifer. This aquifer is con- nected to a deeper aquifer that serves more than 10,000 people within 2 miles down- gradient of the site. Decision: • Compact, grade, and cap the landfill; remedy will conform to RCRA Subtitle D closure re- quirements. • Construct a drainage system, a methane venting system, and a security fence. • Implement an appropriate monitoring program. Contacts: • Region: Rick Schwarz FTS 254-1252 • Headquarters: Joe Gormley FTS 382-5755 BURLINGTON NORTHERN REGION V MINNESOTA (Approved 06/04/86) Description: • The site has operated as a rail- road tie treatment plant since 1907. Wastewater generated from this process has been sent to an unlined surface im- poundment for disposal. This practice has contaminated both the soils and the ground water beneath the impound- ment. The primary contami- nants are PAHs, heterocycles, and phenols. All wastewater and liquid creosote have been removed from the impound- ment. The principal pathway for exposure is the ground water. Ground water monitor- ing results indicate that ground water contamination is restricted to a relatively small area downgradient of the site. ------- Decision: • Onsite biological treatment of creosote sludges and conta- minated soils, with final cap- ping after treatment.

From 1970 to 1979, the site was used for dewatering and disposing of metal hy- droxide sludges, waste cool- ants, and soluble oils. Four onsite disppsal areas have been identified, including six unlined pits. Contamination that consists primarily of heavy metals and cyanide has been found in site soils, adja- cent wetland surface water and sediments, and ground water. An endangerment as- sessment at the site defined- three receptor pathways: (1) human contact and ingestion of contaminated sludges and soils at the site, (2) human in- gestion of ground water, and (3) potential aquatic life expo- sure in surface water. Decision: • Excavate, treat with lime to immobilize metals, and dis- pose of contaminated soils, sediments, and sludges at an offsite RCRA facility. • Confirm the extent of ground water contamination, and pump and treat onsite. • Drain affected wetland.

General rubble, domestic refuse, and industrial wastes, including drums and plating materials, are scattered about the site. The site was placed on the NPL in December 1982. A ROD was signed in March 1985 to implement a remedial action consisting of excavation and removal of containerized waste and contaminated soil and onsite treatment of soil containing excessive levels of cyanide. A phased FS was begun in September 1985 to address drinking water con- tamination; several volatile organic compounds have been found in private wells surrounding the site. A public health assessment was prepared to evaluate the health risks associated with consumption of contaminated ground water. Decision: • Install whole-house carbon fil- tration systems in affected year-round residences and distribute bottled water to seasonal residents. • Sample and monitor to eval- uate the effectiveness and lifetime of the carbon filters and to replace them after breakthrough. • Dispose of spent filters in ac- cordance with RCRA. • Consider an operable unit remedial action until final re- medial measure is imple- mented. Contacts: • Region: Ken Wallace FTS 886-9296 • Headquarters: Nancy Willis FTS 382-2347 FIELDS BROOK REGION V OHIO (Approved 9/30/86) Description: • The site is defined as a 3.5-mile stretch of Fields Brook and the surrounding 5.6-square-mile watershed. This section of the brook flows through an area of Ohio that contains a wide variety of industrial sources which have contaminated the sediment with organic and heavy metal pollutants. The amount of contaminants entering the brook has been reduced sub- stantially because of discharge requirements stipu- lated in the National Pollutant Discharge Elimination System (NPDES) permit program. A public health risk evaluation concluded that excess life- time cancer risks from each of the potential exposure path- ways (ingestion of sediment, dermal absorption from wad- ing in surface water, and fish consumption) were all greater than 10 ~6. Decision: • Excavate, temporarily store, and dewater contaminated sediments. • Thermally treat a portion of the dewatered sediments and use solidification/landfilling for the remainder. • Ash will be treated for hazar- dous waste characteristics; if the waste is determined to be hazardous, it will be treated in a RCRA-permitted disposal facility. • Provide long-term monitoring.

OK X ------- ONSITE INSIGHTS STATUS OF THERMAL DESTRUCTION UNIT TEST BURN REMOVAL ACTION PEAK OIL, FLORIDA REGION IV Background The use of the thermal destruc- tion unit (SHIRCO) at the Peak Oil, Florida, site represents the initial use of the system's full- scale mobile unit. Previously, only demonstration units have been used (burning only 1 ton per day) at sites such as Tibbetts Road, New Hampshire (Region I); Indian Town, Florida (Region IV); and Times Beach, Missouri (Region VII). At pre- vious demonstrations, the unit has treated such contaminants as PCBs, dioxin, and pesticides. Operation The process involves mixing waste sludge with lime prior to feeding the sludge into the unit. The system took 2 months to set up (including completion of delivery on site), and the unit began operation at the site in December 1986. Design problems with the feed system (it was initially only able to burn 20 tons per day) pre- vented continuous operation un- til March 27,1987. The system is now burning 60 tons per day. (The advertised capacity is 85 tons per day.) The estimated duration of the burn is 6 months, and the opera< tion costs $225 per ton. Status Ash from the unit shows no PCBs. Lead is still being de- tected but at levels low enough to pass the EP Toxicity Test. The test burn is anticipated in mid-April 1987.
