3.6. Sample Containers and Preservation <br /> Pre-cleaned containers will be supplied by the laboratory and will not be rinsed prior to sample <br /> collection. No preservative will be added to the containers. ' <br /> 1 <br /> 3.7. Disposal of Residual Materials <br /> In the process of collecting environmental samples at the Sante Fe Road Disposal Site, the <br /> CIWMB sampling team will generate different types of potentially contaminated investigation- <br /> derived waste (IDW)that may include: <br /> ■ Used personal protective equipment (PPE) <br /> ® Disposable sampling equipment <br /> ■ Decontamination fluids <br /> The U.S. EPA's National Contingency Plan requires management of IDW generated during <br /> sampling comply with all applicable or relevant and appropriate requirements to the extent <br /> practicable. The IDW will contain minor residual amount of the soil/burn ash. These wastes are <br /> not considered hazardous and will be disposed of at a municipal landfill. Used PPE and <br /> ., disposable equipment will be double bagged and placed in municipal refuse dumpster. Any <br /> PPE and disposable equipment that is to be disposed of which can still be used will be rendered <br /> inoperable before disposal. Decontamination fluids that will be generated during sampling will <br /> consist of nitric acid, deionized water, residual contaminants, and water with non-phosphate <br /> detergent. The volume and concentration of the decontamination fluid will be sufficiently low to <br /> allow disposal at the site or sampling area. This minimal volume of decontamination fluid will be <br /> disposed of to the sanitary sewer system. <br /> If hazardous or radioactive material are found during sampling screening activities, appropriate <br /> level of notification and response procedures will be implemented in accordance with the Site <br /> Specific Health and Safety Plan. <br /> 3.8. Analytes of Concern <br /> Analytes of concern at this site are residual heavy metals from burning solid waste and any <br /> unbumed organic materials left in the soil matrix. <br /> 3.9. Analytical Procedures <br /> Each sample container's headspace will be tested using the GMI 422 Gas Surveyor. After field <br /> screening the sample containers will be capped,sealed and labeled (see packaging procedures), <br /> and sent to CIWMB's contract laboratory, ExcelChem,where composite samples will be analyzed for <br /> CAM 17 metals, pH, reactivity, ignitability,TPH T Diesel (EPA Method 602/8020/8015m), <br /> organochlorine pesticides/PCBs (EPA Method 608/8080)and WET(to determine if STLC is <br /> exceeded). Discrete samples will be analyzed for California Assessment Manual (CAM)5 metals by <br /> the Total Test procedure using EPA Method 6010/7000. Samples with the highest concentrations of <br /> lead will also be analyzed for CAM-5 metals using the Waste Extraction Test(WET)procedure (EPA <br /> Method 6010)to determine if Soluble Threshold Limit Concentration (STLC) limits are exceeded.
