r• <br /> i <br /> The groundwa�er samples from monitoring well MW-1 were designated <br /> WS-1, from monitoring well MW-2 the samples were identified as WS- <br /> 2, and from monitoring well MW-3 the samples were designated WS-3. <br /> Upon collection of the groundwater samples, all sampling bottles <br /> were labelled. The label information included the date, time of <br /> sampling, identification number, project name and number, and <br /> analyses requested. Under proper Chain of custody procedures, the <br /> samples were placed on ice inside a thermally-insulated cooler for <br /> subsequent transport to a State-certified analytical laboratory. <br /> A copy of the Chain of Custody form is included in Appendix B. <br /> The transparent PVC bailer was decontaminated with Alconox and <br /> z distilled water prior to re-use between monitoring wells in order <br /> to reduce the possibility of cross contamination. Disposable <br /> teflon bailers were disposed of after the sampling in each well was <br /> completed. Dedicated nylon rope was used to lower the bailer into <br /> each well. <br /> No floating product was noted in the development water, purge <br /> water, or in any of the groundwater samples collected. <br /> Each groundwater sample was analyzed at Chromalab analytical <br /> laboratory and tested for TPHg (EPA Method 5030/8015), TPHd (EPA <br /> Method 3510/8015), BTEX (EPA Method 602) , Total Oil and Grease (EPA <br /> Method 5520 E&F), Purgeable Halocarbons (EPA Me71.thod 501), and <br /> Cadmiumhod 7420), N ckeLea (EMethol (EPA)Method 7590)(, Chromium Eand Zinc Method <br /> (EPA Method 7950) <br /> 1 <br /> 275 GRANT LINE ROAD PAGE 12 <br /> 5� <br /> Fill 11 <br /> 1 �_ <br />
