Spill Description:
During deconstruction activities at the Lorenz-63N66W/30SWSW tank battery, petroleum hydrocarbon impacted groundwater was encountered beneath the produced water sump. There were no indications that the dumplines or produced water sump were leaking. The volume of the release is unknown. Groundwater was encountered in the excavation at approximately 3 feet below ground surface. An initial groundwater sample (GW01) was collected on November 25, 2015, and submitted for laboratory analysis of BTEX. Laboratory analytical results received on November 30, 2015, indicated that the benzene concentration exceeded the CGWQS at a concentration of 96.8 µg/L. The analytical results and excavation details are summarized below. A topographic Site Location Map depicting the general location of the release is attached as Figure 1.
