| Description | This data summary report presents water quality results for groundwater samples collected in April 2022 at the former Lakewood Plaza Cleaners site in Lakewood, WA. The site, listed on the National Priorities List (NPL) as Lakewood Ponders Corner, was added to the NPL due to chlorinated solvent contamination impacting municipal supply wells operated by the Lakewood Water District. The contamination was caused by improper waste disposal at the former cleaners. Groundwater monitoring has been conducted at this site since 1985. The Washington State Department of Ecology’s (Ecology’s) groundwater sampling program at the site has been ongoing since the early 1990s. The U.S. Environmental Protection Agency selected the remedial option of installation and operation of wellhead treatment systems on the Lakewood Water District’s municipal supply wells H1 and H2. This remedial activity is ongoing. The purpose of Ecology’s monitoring program is to evaluate the effectiveness of wells H1 and H2 in containing and treating contaminated groundwater. In April 2022, Ecology collected groundwater samples from five monitoring wells and Lakewood Water District’s municipal well, H1. Tetrachloroethene (PCE) concentrations continue to exceed (not meet) the project cleanup level of 5 micrograms per liter (µg/L) in three wells (MW-20B, MW-16A, LPMW-2). Well MW-20B had a PCE concentration of 179 µg/L. The concentration of PCE in MW-16A was 65.5 µg/L. Well LPMW-2 had a PCE concentration of 9.56 µg/L. PCE was detected in H1 at an estimated concentration of 0.71 µg/L, below the cleanup level of 5 µg/L. |
