An EMP and CAP is being implemented by the Discharger at LHSL. The County implemented the following corrective action measures: a pump-and-treat remediation system that operated from 1996 to 2000 pumping groundwater from LH-8 for air-sparging treatment and reinjection of treated groundwater into LH-18, construction of a final cover which included passive gas vents as part of the monitored natural attenuation (MNA) CAP in 2007, and initiation of a bioremediation pilot study including construction of three injection wells near LH-1 which introduced bio-enhancement media to the NFR groundwater for anaerobic de-chlorination of tetrachloroethene (PCE) and trichloroethene (TCE) in July 2015, a second injection was conducted in November 2018, followed by a first-time aquifer inoculation event with additional dehalococcoides bacteria colonies in February 2019. |
