�. Former Manna Pro Site Page 3 <br /> Quarterly Groundwater Monitoring Report <br /> Project No. 207.2 <br /> April 18, 2005 <br /> 2.0 GROUNDWATER MONITORING <br /> v <br /> The following sub-sections describe the procedures associated with the <br /> L completion of groundwater monitoring and ancillary activities at the site. <br /> 2.1 Groundwater Sample Collection <br /> `' On March 18, 2005, Del-Tech Geotechnical Services of Oakdale, CA mobilized <br /> to the site to complete groundwater monitoring. The groundwater monitoring <br /> L procedure was as follows: Upon arrival, each well was opened and the water <br /> � <br /> ' level allowed to equilibrate. As each well was opened, and prior to taking the <br /> depth to groundwater measurement, a PID organic vapor meter was used to <br /> screen for VOC's in the head space of the wells which were to be sampled. The <br /> depth to groundwater was then measured by lowering an electronically <br /> actuated air 1 water interface detector suspended from a polyethylene <br /> �. measuring tape calibrated to the nearest 0.01 foot (see groundwater <br /> monitoring data sheets in Appendix B). A careful notation was made of the <br /> depth to groundwater as measured by the device. No measurable free product <br /> V was observed in the wells. <br /> +�y,r Each well to be sampled was pumped with a Waterra pump with dedicated <br /> vinyl tubing. Well water was containerized in 55-gallon, DOT approved <br /> polyethylene drums, properly labeled, and temporarily stored on-site. The <br /> rate of well purging was monitored, and each well was purged of at least three <br /> casingvolumes or until the <br /> groundwater parameters (temperature, <br /> conductivity, and pH) stabilized indicating that water representative of actual <br /> aquifer conditions was entering the well. Groundwater parameter <br /> stabilization was characterized by three successive readings within 10 percent. <br /> After the wells recharged to at least 80 percent of their original volume, <br /> i, samples were collected from them using methods described below. <br /> Wells purged with a Wattera pump were sampled directly from the dedicated <br /> L tubing. Before, and in between uses, all re-usable sampling equipment was <br /> washed using a portable steam cleaner. Disposable gloves were worn by the <br /> sampling technician while collecting all samples. The gloves were changed <br /> L between the collection of each sample to reduce the potential for cross- <br /> contamination. <br /> Extreme care was exercised while collecting samples to prevent agitation of <br /> the water contained in the bailer. Water samples were transferred from the <br /> L bailer into 40 ml VOA vials preserved with hydrochloric (provided by the <br /> analytical laboratory). All samples were checked for head space bubbles, <br /> 2937 Veneman Ave.,#13240 Geo-Phase Environmental Inc. Phone (209) 569-0293 <br /> Modesto, CA 95356 Fax(209) 569-0293 <br />
