| Abstract |
The GE Moreau site, located in the town of Moreau, Saratoga County, New York, is situated in a semi-rural setting with single family houses nearby. These houses rely on individual drinking water wells as their water supply. From 1958 to 1968, the site was used as an industrial waste disposal site. An evaporative pit received approximately 452 tons of waste material generated by the General Electric Company (GE). The waste materials include trichloroethylene (TCE), polychlorinated biphenyls (PCBs), spent solvents, oils, sludge and other miscellaneous waste. In late 1982, elevated levels of TCE were found onsite in the ground water. The town of Moreau installed activated carbon filter systems on the drinking water systems of 70 homes believed to be down gradient of the site and therefore affected, or potentially affected, by contaminants emanating from the site. In the summer of 1983, EPA initiated negotiations with GE to address the offsite contamination problems. The primary contaminants of concern affecting the ground water, surface water and river include; TCE, dichloroethylene, VOCs and organics. Approximately 8,600 cu. yds. of soil are contaminated with PCBs. The selected remedial action includes; utilize the soil-bentonite cutoff wall constructed in 1984 around the former disposal area to contain the source of offsite ground water contamination; utilize the air stripping system installed in fall 1985 to remove VOCs offsite at Reardon Brook; remove 8,600 cu. yds. Of PCB-contaminated soil adjacent to the disposal area and place within the slurry wall containment area (this was completed in late summer 1985); capping of the disposal area in conformance with New York State Department of Environmental Conservation requirements; and extension of public water mains to approximately 100 homes. The estimated capital cost of the selected alternative is $16,382,000 with annual O&M of $78,000. |
