Excavation activities were initiated, and groundwater was encountered in the excavation area at approximately 6 feet below ground surface (bgs). A groundwater sample (GW01) was collected from the excavation and submitted to Origins Laboratory for analysis of benzene, toluene, ethylbenzene, and total xylenes (BTEX) by USEPA Method 8260C. Analytical results received on July 28, 2015, indicated that benzene and total xylenes concentrations in groundwater sample GW01 were above the applicable COGCC Table 910-1 standards. The groundwater sample location is illustrated in Figure 2 and the groundwater laboratory analytical results are summarized in Table 2. 336310 400877072 false 2015-07-28T00:00:00-06:00 40.213796 -104.766789 FEE 1 0 0 false <_x0032_7_approved>true S false 0 Unknown Unknown 0 0 false true false true false 0 2015-07-30T12:07:14.813-06:00 400927000 400927000 FORM 19 SUBMITTED 400927000.pdf 400927000 400927038 OTHER Sarchet Unit 63N66W22SENW - Form 27.pdf 2477937 400927000 1 SPILL 2015-07-28T00:00:00-06:00 County Roy Rudisill
