Publication Summary

Routine monitoring was conducted at Lakewood/Plaza Cleaners in May 1993 in compliance with the Record of Decision. Ground water samples were collected from eight monitoring wells. The analytical quantitation limits used were above the State Model Toxics Control Act cleanup levels for ground water, therefore contaminants were detected in only a few wells this sample round.

The analytical quantitation limits used were above the State Model Toxics Control Act cleanup levels for ground water; therefore, contaminants were detected in only a few wells this sample round.

Low levels of tetrachloro-ethylene and 1,2 dichloroethylene were detected in two monitoring wells. One well continues to have the highest concentrations of any of the wells sampled. Tetrachloroethylene concentrations increased in this well from 340 ppb in December 1992 to 700 ppb in May 1993. Tetrachloroethylene concentrations are similar to those reported in previous sample rounds. Two soil samples were collected from a nearby drainage ditch due to concern of runoff from on-site contaminated soil stockpiles. No volatile organics were detected in the soil samples.
