Work Plan- Phase IIA ESA Page 5 <br /> Former Karlson Trucking Facility <br /> Project No. 191.2 <br /> September 22, 1998 <br /> • Metals (Cadmium, Chromium, Nickel, Lead and Zinc). <br /> The detection limits for those compounds are as follows: <br /> Compound TEPH TPH-Gasoline Benzene Toluene Ethyl Benzene Xylene <br /> Detection Limit 5.0 1.0 3.0 3.0 3.0 3.0 <br /> Units mg/kg mg/kg gg/kg µg/kg µg/kg µg/kg <br /> Compound Cadmium Chromium Nickel Lead Zinc <br /> Detection Limit 0.50 0.50 0.50 0.50 0.50 <br /> Units I mg/kg mg/kg mg/kg mg/kg mg/kg <br /> 2.3 Stockpile Soil Sampling <br /> Twenty shallow hand auger soil borings will be completed in a id pattern <br /> through a soil stockpile at the site. These borings will be comple a to <br /> feet below ground surface using a 3.75" diameter hand auger. Soil samples <br /> w l be collected at th se of each boring for composite for analysis. It is <br /> proposed tha two composite samples a analyzed. The collection procedures <br /> are described in sec ion above. Sampling handling procedures are <br /> described in section 2.1.2 above. All sampling equipment will be <br /> decontaminated using a three bucket wash system and TSP or Alconox soap. <br /> The composite soil samples from the borings would be analyzed as described <br /> above in section 2.2. <br /> 2.4 Stained Soil Sampling <br /> Ten shallow hand auger soil borings will be completed in a grid pattern <br /> through an area of stained soil a underneath the pole barn. These <br /> borings will be completed five feet belo�.;�ground surface using a 3.75" <br /> diameter hand auger. Soil samples wi a collected at two feet and at the <br /> base of each boring for composite for analysis. It is'p p ed that two <br /> composite samples be analyzed, one composite from two feet and one from <br /> five feet. The collection procedures are described in section 2.2 above. <br /> Sampling handling procedures are described in section 2.1.2 above. All <br /> sampling equipment will be decontaminated using a three ucket wash <br /> system and TSP or Alconox soap. The oin osite soil samples rom the <br /> borings would be analyzed as above in section 2.2. <br /> 2937 Veneman Avenue,Suite B240 Geo-Phase Environmental Inc.
