<br />(e.g. bailers, filtering apparatus). Analysis of this type of <br />sample for volatile organics verifies decontamination <br />effectiveness. <br /> <br />Sample handling <br /> <br />Samples will be packaged and delivered to the laboratory in a <br />way to best preserve the integrity of the samples. Ice chests <br />will be used as shipping containers. Sample containers will be <br />placed on ice in insulated coolers. Chain of Custody forms will <br />be enclosed in each cooler. Transport of samples to the <br />laboratory will be by hand delivery by MFG sampling personnel. <br /> <br />Chain of Custody forms will be completed in the field at the <br />time of sample collection. When custody changes, signatures of <br />personnel regulating the sample exchange will be put on the form <br />along with the date, time and company affiliation. A signed and <br />completed copy of the Chain of Custody form will be included in <br />the final report. <br /> <br />Sample analysis <br /> <br />Water samples will be analyzed in accordance with the guidelines <br />of EPA SW-846 (Test Methods for Evaluatinq Solid <br />Waste-Physical/Chemical Methods) third ed., Revised 12/87, EPA <br />600/4-79-020 (Methods for Chemical Analyses of Water and <br />Wastes), Revised March 1983, and Standard Methods for the <br />Examination of Water and Wastewater, 16th ed., 1985. Water <br />samples will be analyzed in the laboratory for the following <br />parameters: <br /> <br />1) <br /> <br />General chemistry: calcium, magnesium, sodium, potassiu~, <br />carbonate, bicarbonate, sulfate, fluoride, nitrate, <br />phenolphthalein alkalinity (CaC03), alkalinity (CaCO3), <br />hardness (CaC03), chloride, pH, specific conductance, and <br />total dissolved solids (TDS). <br /> <br />2) <br />3) <br /> <br />Total organic carbon (TOC). <br /> <br />Trace metals: arsenic, barium, cadmium, chromium, copper, <br />iron, lead, manganese, mercury, selenium, silver, and <br />zinc. <br /> <br />4) <br /> <br />Volatile organic compounds: Priority Pollutant List (40 <br />CFR 122). <br /> <br />A laboratory quality assurance/quality control (QA/QC) program <br />will be employed to ensure the analytical accuracy and <br />precision. The program will consist of a series of laboratory <br />duplicates and spiked samples that will be analyzed at the same <br />time as the original field samples. The results of these <br />analyses and comprehensive QA/QC reporting will be provided by <br /> <br />8 <br />
