• 3• WATER SAMPLE COLLECTION PROTOCOL <br /> Groundwater samples will be collected directly through the hollow-stem drilling <br /> augers using pre-cleaned Teflon bailers. The groundwater samples will be <br /> carefully transferred from the bailers into proper containers obtained from the <br /> analytical laboratory. All water samples will be analyzed for Priority Pollutant <br /> Metals and Total Cyanide. In the event that seepage has occurred from <br /> surrounding properties, two water samples will be analyzed for volatile and semi- <br /> volatile organics, pesticides, and oil and grease. Groundwater analysis for <br /> volatile organic compounds will be placed into volatile organic analysis (VOA) <br /> vials. After filling and capping, each vial, they will be inverted and tapped to <br /> ensure the absence of air bubbles. All containers will be individually labeled and <br /> placed in a field cooler for preservation. Each ground water sample will be <br /> placed into the appropriate container for the chemical species being tested (Table <br /> 4). Standard chain-of-custody procedures will be implemented in the field to <br /> document sample collection, handling, and analytical requests. <br /> 4. COMPOUNDS AND ANALYTICAL METHODS <br /> Groundwater samples will analyzed for constituents using the methods of analysis <br /> outlined in Table 3. <br /> • Table 3 <br /> Groundwater Analysis <br /> GROUNDWATER SAMPLE CONSTITUENT & <br /> IDENTIFICATION ANALYTICAL METHOD <br /> GWO and GWS Method 624, 625, 608, 503A <br /> EPA method 8240 <br /> GWO, GWI, GW2, GW3, GW4, GW5 EPA Priority Pollutant Metals (13) <br /> Total Cyanide <br /> IV. QUALITY ASSURANCE/QUALITY CONTROL <br /> This section details the quality assurance/quality control procedures for the collection and <br /> handling of environmental samples at the site. <br /> Proper collection and handling are essential to ensure the quality of a sample. Each sample will <br /> be collected in a suitable container, preserved correctly, and stored prior to analysis no longer <br /> than the maximum allowable holding time according to EPA protocol. Sample containers and <br /> preservatives that will be used for the site are listed in Table 4. <br /> • <br /> 8 <br /> ERICKSON, Inc. <br /> Specialized Service to Industry Since 1942 <br />
