Approximately 200 cubic yards of impacted material were removed and transported to Front Range Regional Landfill in Erie, Colorado. Groundwater was encountered in the excavation 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 27, 2014, indicated benzene concentrations were in exceedance of the applicable COGCC Table 910-1 groundwater standards, causing this release to be reportable to the State. Groundwater analytical results are summarized in the attached Table 1 and laboratory analytical report. 328953 400720388 false 2014-10-27T00:00:00-06:00 40.040111 -104.872880 FEE 1 0 0 false <_x0032_7_approved>false I false 0 Unknown Unknown 0 0 false false false true false 0 2014-10-30T07:22:42.22-06:00 400720388 400720388 FORM 19 SUBMITTED 400720388.pdf 400720388 400720389 ANALYTICAL RESULTS Analytical Table and Laboratory Report.pdf 860705 400720388 400720391 TOPOGRAPHIC MAP Coughlin Red VV 22-1, 22-2, Wagner Red VV 22-7, 22-8 Figure 1.pdf 1397029 400720388 1 SPILL 2014-10-27T00:00:00-06:00 County Tom Parko
