Spill Description:
Historical impacts were discovered during abandonment activities at the Miller Estate 8-13K production facility. The release became State reportable on December 6, 2018, due to the quantity of impacted soil excavated. Groundwater was encountered within the excavation at ~15 feet bgs. A groundwater sample (GW01) was collected and submitted to Origins Laboratory for analysis BTEX by USEPA Method 8260C. Analytical results received on December 7, 2018, indicated that the benzene, ethylbenzene, and total xylenes concentrations in groundwater sample GW01 were above the COGCC standards. Soil excavation activities are ongoing and will be summarized in a forthcoming Supplemental Form 19 Spill/Release Report. A topographic Site Location Map showing the geographic setting of the release is provided as Figure 1. The groundwater sample location is illustrated on Figure 2. The groundwater analytical results are summarized in Table 1. The analytical laboratory report is provided as Attachment A.
