program are listed in Table C-3. Sample containers were properly <br /> cleaned according to the EPA protocol for the individual analysis. <br /> i Sample Shipment <br /> At the end of the sampling event, the sampler transported the samples <br /> on ice, in coolers, to EMCON's laboratory. Upon receipt of samples by <br /> EMCON laboratory personnel , a unique sample identification number was <br /> assigned to each sample container. This number was recorded on the <br /> chain-of-custody record and was used to identify the sample in all <br /> subsequent internal chain-of-custody and analytical records. Samples <br /> were routinely couriered to sub-contract laboratories within 24 hours <br /> of receipt at EMCON's laboratory. <br /> Analytical Procedures <br /> The analyses of ground-water and surface-water samples were conducted <br /> in accordance with accepted quantitative analytical procedures. The <br /> following four publications were the primary references for ground- <br /> water sample analyses: <br /> ® Standard Methods for thp FYamina _ion of Water and Waste- <br /> wAlgr <br /> (American Public Health Association, et al . , 1985, <br /> 16th Edition) . <br /> • Methods for Chemical Analysis of Water and Was (U.S. <br /> EPA, 600/4-79-020, March, 1979, with March 1983 revi- <br /> sions) . <br /> • Methods for Organic Chemical Analvsis of Municipal and <br /> Industrial Wastewater (U.S. EPA 600/4-82-057, July 1982) . <br /> • Test Methods for Evaluating Solid Waste; Physical/ <br /> Chemical Methods (U.S. EPA SW-846, November 1986, 3rd <br /> Edition) . <br /> Quality assurance measures were taken to confirm the integrity of the <br /> laboratory data generated during the monitoring program. Laboratory <br /> quality assurance procedures included reporting of method blank, <br /> surrogate spike, and matrix spike analyses. <br /> PJ9 9390102.00D C-6 <br />
