Drinking water wells in the Tacoma, Washington area were sampled for contamination by purgeable halocarbons. The sampling results showed that Lakewood Water District's production Wells H-1 and H-2 were contaminated with 1,2-(trans)dichloroethylene, trichloroethylene and tetrachloroethylene. These wells were taken 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 of in the septic tank and liquid wastes consisting of solvent-contaminated sludges and water draw-off were disposed on the ground outside the cleaners. The cost-effective initial remedial measure for the site is construction of air stripping towers. The 3-year present worth cost for this remedy is estimated to be $1,163,000 and annual operation and maintenance is estimated to cost $82,000.
