Description Annual groundwater monitoring at Lakewood Plaza Cleaners near Tacoma was conducted during June and November 2009.

Four wells had PCE concentrations higher than the MTCA cleanup level of 5 ug/L: monitoring wells MW-20B (160-250 ug/L), MW-16A (67-28 ug/L), LPMW-2 (4.1-11 ug/L), and municipal well H2 (6.8 ug/L).

PCE concentrations have varied since sampling began in 1991, but overall trends indicate that concentrations in well MW-20B are decreasing while concentrations in MW-16A are increasing.

The use of municipal wells H1 and H2 to treat the contaminated groundwater continues since the cleanup goals have not been achieved. Project data indicate that it will take much longer than the projected timeframe to meet the cleanup goals.
