The array of parametric results for each well was <br /> 3 recorded in field notes. (See Field Notes, Appendix B) <br /> r: l 5.11 Groundwater Sampling Procedure <br /> After purging, samples were recovered from each monitoring well to be sampled using a <br /> ,r$ disposable bailer. Water brought to the surface in the bailers was decanted via a discharge <br /> spigot valve so as to completely fill clean glassware supplied by the laboratory. The <br /> sample vials were then tightly closed, labeled for identification, entered into chain-of- <br /> custody control and packed on chemical ice for transport, within 24 hours, to STL's <br /> laboratory in Pleasanton, California. <br /> f:< 5.12 Groundwater Sample Analyses <br /> Each groundwater sample was analyzed for the following suite of analytes. <br /> Analyte Method of Analysis <br /> =` Total Petroleum Hydrocarbons EPA Method 8015M <br /> (quantified as Diesel) <br /> '.
