EPA Method 6010. Soil samples reported to contain total lead at concentrations in excess of 50 <br /> milligrams per kilogram (mg/kg) will be analyzed for soluble lead using the Waste Extraction <br /> Test (WET) EPA method 7000. Samples with a soluble lead concentration greater than or equal <br /> to 5.0 mg/L will be further analyzed using the DIWET procedure followed by the WET analysis <br /> substituting deionized water for the stipulated citric acid. Ten percent of all the samples will be <br /> tested for pH, with half of which will be the same samples analyzed by the DI WET in <br /> accordance with EPA method 9045. <br /> The soil samples from collected from greater than 0.6 meters (2 feet),beginning with the samples <br /> collected from 1.2 meters (4 feet), and the groundwater samples will be included in the petroleum <br /> hydrocarbon investigation. These samples will be analyzed for the following: <br /> Matrix Analyses <br /> Soil/water Gasoline Analysis Package EPA Method 801518020 <br /> Soil/water Total Petroleum Hydrocarbons as Diesel Modified EPA Method 8015 <br /> Soillwater Total Petroleum Hydrocarbons as Oil Modified EPA Method 8015 <br /> Soil/water Organolead LUFT Field Manual(May 1988)Protocols <br /> Soil/water Fuel Oxygenate Compounds EPA Method 8260B(if methyl tertiary butyl ether is first <br /> identified with EPA Method 8020,it will be confirmed using EPA Method 826013) <br /> 4.4 Task 4: Investigation-Derived Waste Disposal <br /> Drill cuttings and wash water generated during the field investigation will be contained for <br /> disposal in 208-liter (55-gallon) drums, approved by the United Nations for transport of liquid <br /> and solid wastes. The drums will be stored at the site. The drums will be removed from the site <br /> for disposal within 90 days of initiation of the field investigation. <br /> Soil classified as non-hazardous will be sent to TPS Technologies, Inc., for rotary kiln thermal <br /> desorption at either their Oakland, California, or Adalanto, California, facility. This soil may or <br /> may not contain petroleum hydrocarbons, but will be sent for treatment for ease of handling. <br /> Soil classified as hazardous will be sent to Chem Waste Management for disposal at their Class I <br /> Kettleman Hills, California, facility. <br /> 4.5 Task 5: Site Investigation Report <br /> IT Corporation 5 120Austin_wkp <br />
