if work proceeding under an approved Form 27: | 9264 | | | | Spill Description: | | During abandonment activities at the Harold R Mixon Gas Unit-62N67W/25SWSW tank battery, petroleum hydrocarbon impacted groundwater was encountered while removing a 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 5 feet below ground surface. One groundwater sample was collected and submitted for laboratory analysis for BTEX. Laboratory analytical results received on July 2, 2015 indicated that benzene and total xylenes concentrations exceeded the CGWQS at concentrations of 115 µg/L and 1,840 µg/L, respectively. The groundwater analytical results are summarized in Table 1. Excavation activities are ongoing at the site. The analytical results and excavation details will be provided in a supplemental report. A topographic Site Location Map showing the general location of the release is attached as Figure 1. | | |
