Superfund Record of Decision (EPA Region 10): Ponders Corner Site, Washington (second remedial action), September 1985. Final report
Ponders Corner, or the Lakewood site as it is identified in the National Priorities List, is located in Pierce County, Washington, south of the city of Tacoma. In July 1981, EPA sampled drinking water wells in the Tacoma, WA area for contamination with purgeable halocarbons. The sampling showed that Lakewood Wells H1 and H2 were contaminated with 1,2-dichloroethylene (1,2 DCE), trichloroethylene (TCE), and tetrachloroethylene. In mid-August 1981 Lakewood water district took wells H1 and H2 out of production. It was determined that the septic tanks and the ground-disposal area of a commercial cleaners were the probable source of well-water contamination. Solvents used in the dry cleaning process were disposed in the septic tank and liquid wastes consisting of solvent-contaminated sludges and water draw-off were disposed on the ground outside the cleaners. Initial Remedial Measures (IRMs) implemented in June 1984 at the site included the construction of air stripping towers for wells H1 and H2. The recommended alternative for this second remedial action are included.
