Shallow groundwater was encountered at two feet bgs in the sump's excavation. Four sidewall soil samples and one groundwater sample were collected and submitted for laboratory analysis. Soil samples were analyzed for BTEX, TPH - GRO by Method 8260, and TPH - DRO and RRO by Method 8015. The groundwater sample was analyzed for BTEX by Method 8260. The groundwater results were received on September 20 indicating benzene levels at 5.92 ug/L exceeding Table 910-1 allowable groundwater concentrations. All four soil samples were submitted to the laboratory and the sample with the highest PID reading was analyzed. The laboratory analytical results for soil sample (N01@1.5') were ND for all constituents. Based on the groundwater results, the remaining three soil samples will be analyzed. 401408362 false 2017-09-20T00:00:00-06:00 40.201320 -104.847968 FEE 1 0 0 false <_x0032_7_approved>false S false Unknown 0 Unknown 0 0 false false false false true 0 2017-09-20T10:09:42.207-06:00 401415310 401415310 FORM 19 SUBMITTED 401415310.pdf 401415310 401415332 TOPOGRAPHIC MAP Erickson_Birckle_P25-4JI_Fig1_area_20170920.pdf 274742 401415310 401415335 SITE MAP Erickson_Birckle_P25-4JI_Fig2_dig_20170926.pdf 234704 401415310 401415336 ANALYTICAL RESULTS SiteClearance_Erickson Birckle P25-4JI_SoilTable1.pdf 160922 401415310 401415338 ANALYTICAL RESULTS SiteClearance_Erickson Birckle P25-4JI_GWTable2.pdf 157186 401415310 401415340 ANALYTICAL RESULTS Y709256 KMG-Erickson Birckle P25-4JI (rev1).pdf 917094 401415310 1 SPILL 2017-09-20T00:00:00-06:00 Weld County Roy Rudisill

Concentrations of all confirmation sidewall soil sample analyzed consituents were either not detectable at the lab's detection limit or below COGCC Table 910-1 allowable concentrations. Both pH and EC were within COGCC allowable thresholds. Groundwater was encountered in the excavation at two feet below ground surface and one sample was collected for laboratory analysis of BTEX. The laborator results indicated benzene exceeded COGCC Table 910-1 allowable concentrations at 5.92 ug/L. Toluene, ethylbenzene, and total xylenes were detected in the groundwater sample, but below Table 910-1 allowable concentrations. No impacted soil was removed from this location. Site geology includes sandy loam/clay. 2 4 1268 1426 1214 2552 687 0 0 0 370 false false 0 true false true false false false false false false false false false 14 11 24 401415310 1 2017-09-28T00:00:00-06:00 false false true false On September 19, 2017, environmental testing activities associated with a produced water sump closure was conducted at the Erickson Birckle P25-4JI Tank Battery location. Shallow groundwater was encountered at two feet below ground surface in the sump's excavation. Due to operations conducted at the sump and the proximety to groundwater, minor environmental impacts were detected in the groundwater sample.
