Prcceed to first well with clean and decontaminated equipment. <br /> 2 Measurements of liquid surface(s) in the well, and total depth of <br /> 1,104itoring well. Mote ptesence of silt accumulation, <br /> 3. Field check for presence of floating product; measure apparent <br /> thickness. <br /> 4, Purge well prior to collecting samples; purge volume (casing <br /> volumes) calculated prior to removal. <br /> 5. Monitor groundwater for temperature, pH, and specific conductance <br /> during purging. <br /> 6. Collect samples using Environmental Protection _Agency ;EPA) <br /> ` approved sample collection devices, i.e., teflon or stainless steel <br /> bailers or pumps. <br /> 7. Transfer suaples into laboratory-supplied EPA-approved containers. <br /> S. Label samples and log onto chain-of-custody form. <br /> 9. Store samples in a chilled ice chest for shipment to a state-certified <br /> analytical laboratory. <br /> 10. Decontaminate equipment prior to sampling next well. <br /> EXCELTECH, INC:. <br /> Groundwater Sampling Protocol <br /> Latest Revision: May 3, 1991 <br />
