Remediating contaminated groundwater
Study area beside Black Lake in Thurston County
Black Lake Grocery is an active gas station and convenience store located on the northwest shore of Black Lake in Thurston County. Groundwater samples are collected every 18 months from select wells for total petroleum hydrocarbons as gasoline (TPH-G), and benzene, toluene, ethylbenzene, and xylene (BTEX). The groundwater data are used to evaluate the effectiveness of the installed treatment wall to remediate the petroleum-contaminated groundwater before it reaches Black Lake.
