| Description | Groundwater samples for BTEX and TPH-G were collected in June 2017 from 5 monitoring wells at Black Lake Grocery in Thurston County. Water quality results continue to confirm the surficial aquifer is contaminated with petroleum products. Contaminant concentrations continue to not meet (exceed) cleanup levels in four of the sampled wells, including two wells downgradient of the treatment wall that was installed in 2004. Contaminant concentrations decrease significantly after passing through the wall, but the continued presence of high concentrations in wells on the downgradient side and near the shoreline suggests that petroleum constituents may be migrating to Black Lake. Groundwater monitoring downgradient of the treatment wall should continue to determine if it’s remaining effective in remediating the contaminated groundwater. |
