' Former Manna Pro Site Page 3 <br /> Quarterly Groundwater Monitoring Report <br /> Project No 207 2 <br /> August 18, 2000 <br />' 2.0 GROUNDWATER MONITORING <br /> The following sections describe the procedures associated with the completion <br />' of groundwater monitoring at the site along with documenting the disposal of <br /> the well purge water associated with groundwater monitoring activity <br />' 2.1 Groundwater Sample Collection <br />' On January 21, 2000, Del-Tech Geotechnical Services of Oakdale, CA <br /> mobilized to the site to complete groundwater monitoring The groundwater <br /> monitoring procedure was as follows Upon arrival, each well was opened and <br />' the water level allowed to equilibrate As each well was opened, and prior to <br /> taking the depth to groundwater measurement, a PID organic vapor meter <br /> was used to screen for VOC's in the head space of the wells which were to be <br /> sampled The depth to groundwater was then measured by lowering an <br /> electronically actuated air / water interface detector suspended from a <br /> polyethylene measuring tape calibrated to the nearest 0 01 foot (see <br /> Igroundwater monitoring data sheets in Appendix B) A careful notation was <br /> made of the depth to groundwater as measured by the device No measurable <br /> free product was observed in the wells <br /> Each well to be sampled was pumped by inserting a submersible pump into <br /> the well and lowering it to bottom Well water was containerized in 55 gallon, <br /> DOT approved polyethylene drums, properly labeled, and temporarily stored <br /> on-site The rate of well purging was monitored, and each well was purged of <br /> at least three casing volumes or until the groundwater parameters <br /> (temperature, conductivity, and pH) had stabilized indicating that water <br /> representative of actual aquifer conditions was entering the well <br /> Groundwater parameter stabilization was characterized by three successive <br /> readings within 10 percent After the wells had been allowed to recharge to at <br /> least 80 percent of their original volume, samples were collected from them <br /> using methods described below <br /> A stainless steel bailer belayed on a clean stainless steel line was used to <br /> Icollect each sample Bailer cleanliness was verified by collecting a bailer <br /> blank (pouring distilled water through the bailer and collecting it in a VOA <br /> vial) prior to collecting the analytical sample Before, and in between uses, all <br /> sampling equipment was washed using a portable steam cleaner Disposable <br /> gloves were worn by the sampling technician while collecting all samples The <br /> gloves were changed between the collection of each sample to reduce the <br /> potential for cross-contamination <br /> I2937 Veneman Ave ,#B240 Geo-Phase Environmental Inc Phone (209) 569-0293 <br /> Modesto, CA 95356 Fax(209) 569-0293 <br /> r <br />
