Soil samples were collected on Wednesday, May 11, 2016 in the areas of produced water impacts to access electrical conductance (EC), pH, sodium adsorption ratio (SAR) at the surface, and the extent of the vertical produced water impacts. The samples were submitted to the laboratory for rush turn-around on May 12. The results will be recieved in 3 to 5 days. Analytical results will be provided to the COGCC in an assessment report once lab results are received. No soil samples were collected from the areas with visible hydrocarbon impacts. Confirmation soil samples will be collected from these areas once hydrocarbon impacted soils are removed. A site diagram showing lateral extent of surface impacts and soil sample collection locations is attached. The site geology is characterized as the Tertiary White River Group (Symbol Twr) including the Brule Formation and overlying Arikaree Formation. The site soils at the Wildhorse 16 SWD facility consist of the Epping Silt Loam (Unit #27), occupying 0 - 9% slopes, over the southern 1/3 of the facility, and the Otero sandy loam (Unit #46) 0 - 3% slopes northern 2/3 of the facility. 100 0 500 Liquid inside containment structure still to be collected due to on-going incident investigation. BBLs recovered will change and be updated as a result. Most of the oil is presumed to have burned off during the fire considering how little oil was seen on-site directly following the incident. Once incident investigation is complete and equipment removed from site, impacted soils will be excavated and removed till levels below Table 910-1 are achieved and confirmed via analysis of confirmation soil samples. 950 1 0 0 3005 370 0 0 0 0 false false 0 0 false false false false false false true true true false true true Thread was being aborted.
