Sample Shipment and Chain-of-Custody <br /> All samples will be shipped directly from the site to the analytical <br /> laboratory in sealed storage coolers with ice or blue ice. Chain of <br /> custody will begin at the time of sample collection by placing the <br /> packaged and labeled samples into the cooler. Field documentation <br /> will be completed at this time and samples will be in the possession of <br /> a designated field sample custodian until received by the analytical <br /> laboratory. When coolers are picked up, custody will then be <br /> transferred to the sample carrier. <br /> Table 2 <br /> Sample Preparation, Analytical Methods and Target Detection Limits for Soil <br /> and Groundwater Analyses <br /> SOIL <br /> Constituent Preparation Analysis MDL <br /> TPH-D EPA Method 3550 EPA Method 8015 (Mod.) 1 mg/kg <br /> TPH-G EPA Method 3550 EPA Method 8015 (Mod.) 1 mg/kg <br /> BTEX EPA Method 5030 EPA Method 8020 5 gg/kg <br /> Total Lead ICP 6010 25 mg/kg <br /> VOCs EPA Method 8240 0.5 mg/kg <br /> SVOCs EPA Method 8270 0.5 mg/kg <br /> PCBs EPA Method 8080 50 gg/kg <br /> WATER <br /> Constituent Preparation Analysis MDL <br /> TPH-D - EPA Method 8015 (Mod.) 50 gg/l <br /> TPH-G - EPA Method 8015 (Mod.) 50 gg/1 <br /> BTEX - EPA Method 602 0.5 gg/1 <br /> Total Lead EPA Method 239.1 10 gg/l <br /> VOCs EPA Method 601 0.5 jig/1 <br /> SVOCs EPA Method 625 50 gg/l <br /> PCBs EPA Method 608 0.2 gg/1 <br /> Note: MDL=Maximum Detection Limit <br /> -------------------- <br /> 1 Staff Report of the California Regional Water Quality Control <br /> Board, Central Valley Region, A Compilation of Water Quality <br /> Goals, November 1989.
