Approximately 2 bbls of oil and produced water was released onto unlined containment. A hydro-vac truck was used to recover approximately 0.5 bbls of the released oil and produced water. The petroleum hydrocarbon impacted soil is being excavated. Groundwater was encountered in the excavation at approximately 7 feet bgs. Laboratory analytical results received on April 10, 2015 confirmed BTEX impacts to groundwater above the CGWQS. The groundwater analytical results are summarized in Table 1. Additional soil and groundwater samples will be collected from the excavation. The analytical results and excavation details will be provided in a supplemental report.
