� � 99 108017 <br /> selected metals Cadmium(Cd), Chromium(Cr)&Lead(Pb). Sampling <br /> results showed no indication of elevated concentrations of explosive, Cd, <br /> Cr or Pb. See Fi urg e 4A <br /> (2) Discharge Points of Floor Drains & Draina�e Structures - <br /> Sample LLO1-17(Loadline 1) collected from bare soil on the south side of <br /> the Boilerhouse, Building 1L-24 was analyzed for explosives and select <br /> metals (Cd, Cr and Pb). Sampling results showed no indication of elevated <br /> concentrations of expl�sive, Cd, Cr or Pb. See Figure 4A - <br /> (3) Adjacent to Load Lines Above Ground Stora�e Tanks (ASTs) - <br /> Surface soil Sarnple LL02-18(Loadline 2) collected adjacent to <br /> Boilerhouse above ground storage tanks (ASTs), Sample LL03-22 <br /> collected adjacent to Loadline 3 ASTs and Sample LL04-18 collected <br /> near Loadline 4 ASTs to assess potential soil contamination related to the <br /> ASTs were analyzed for total petroleum hydrocarbons (TPH). Sample <br /> LL02-18 (222.0 mg/kg) and LL03-22 (1191.0 mg/kg) exceeds the <br /> calculated Nebraska Department of Environmental Quality(NDEQ) soil <br /> cleanup guidance of 100 mg/kg. Sample LL04-18 contained TPH at 47 . <br /> mg/kg,which is below the calculated NDEQ soil cleanup guidance. See <br /> Fit?ure 4B,4C and 4D <br /> Soil boring samples were taken adjacent to the pair of empty 30,000 gallon <br /> fuel oil ASTs located on the respective Loadline and were analyzed for <br /> total petroleum hydrocarbons (TPH)and target compound list(TCL) semi- <br /> volatile organic compounds(SVOCs). Sample LL2SB001(Loadline 2) <br /> and Sample LL2SB002(Loadline 2)results indicated TPH is well below <br /> the calculated NDEQ soil cleanup guidance. Sample LL3SB001(Loadline <br /> _ 3) and Sample LL3SB002(Loadline 3) exceed the calculated NDEQ soil <br /> cleanup guidance in the 2-3 ft bgs intervals but below the guidance in the <br /> 14-16 ft below ground surface (bgs) interval. Lead was detected well <br /> �" below USEPA Residential and Industrial screening levels. See Fi ur� e 4B <br /> and 4C <br /> 0 Non-Explosives Wastewater Cesspool(NEWWCPs)- <br /> Samples L1P03(Loadline 1) and LSP10(Loadline 5)were collected form the <br /> bottoms of the NEWWCPs and analyzed for TCL,VOCs,TCL SVOCs,TAL <br /> Inorganics andlor explosives. Attempts were made to collect samples from <br /> the 1 foot interval immediately above the water table. Explosives were not <br /> detected. VOCs and SVOCs were not detected concentrations exceeding 1 <br /> hg/g and are below Residential RBC's. See Figure 4A and 4E <br /> � 3 . <br />
