Superfund Record of Decision (EPA Region 2): Pomona Oaks Well Contamination Site,Galloway Township, Atlantic County, NJ. (First Remedial Action), September 1990

摘要

The 354-acre Pomona Oaks Well Contamination site is comprised of a 193-residencesubdivision and an adjacent shopping center in Galloway Township, Atlantic County, New Jersey. The site overlies a surficial unconsolidated sand aquifer. Home construction at the site began in 1972, and private wells within the surficial aquifer were initially used as the water supply. In 1982, onsite residents complained of foul tasting well water, and subsequent investigations from 1982 to 1985 confirmed the presence of onsite ground water contamination. Possible contamination sources include two nearby gas stations, a salvage yard, a dry cleaner, and onsite residential septic tanks. In 1985, all homes were hooked to a municipal water supply by the State, eliminating public exposure to ground water contamination. Further sampling conducted from 1986 to 1990 revealed only low-level ground water contamination. The Record of Decision (ROD) provides a final remedy for the ground water. Because ground water contaminant levels no longer exceed health-based or State standards, there are no contaminants of concern at the site.
