Approximately 240 cubic yards of impacted soil have been removed and transported to the Kerr-McGee land treatment facility in Weld County, Colorado for disposal. Groundwater was encountered in the excavation area at approximately 10 feet below ground surface (bgs). A groundwater sample (GW01) was collected and submitted to Origins Laboratory in Denver, Colorado for analysis of benzene, toluene, ethylbenzene, and total xylenes (BTEX) using USEPA Method 8260B. Analytical results received on October 31, 2014, indicated benzene, toluene, and total xylenes were in exceedance of the applicable COGCC Table 910-1 groundwater standards, causing this release to be state reportable. Groundwater analytical results are summarized in the attached Table 1 and laboratory analytical report. 317879 400722328 false 2014-10-31T00:00:00-06:00 40.040113 -104.872339 FEE 1 0 0 false <_x0032_7_approved>true 9106 S false 0 Unknown Unknown 0 0 false false false true false 0 2014-11-03T07:16:53.577-07:00 400851665 See attached COGCC approved Form 27. 400851665 400851665 FORM 19 SUBMITTED 400851665.pdf 400851665 400851680 OTHER 9106_Albert Sack F27 052815.pdf 21786100 400851665 1 SPILL 2014-10-31T00:00:00-06:00 County Roy Rudisill
