purging process Samples were then collected after the reading became <br /> stable The purged waters in wells MW-1, MW-2 and MW-3 were <br /> observed to be cloudy <br /> 7.4 Groundwater Sampling <br /> Groundwater samples were obtained with a disposable plastic bailer The plastic <br /> bailer was lowered into the well on a string, allowed to fill up and pulled to the <br /> surface Observations were made for floating product, sheen and odor Water was <br /> decanted slowly from the bottom of the bailer into clean glass containers with caps <br /> lined with teflon septa provided by the analytical laboratory Each bailer is <br /> dedicated to only one well and discarded after use One amber-colored, one-liter <br /> bottle was filled with groundwater samples from each well for analysis of TPH as <br /> hydraulic fluid along with 3 polyethylene containers (one 500 mil Polyethylene <br /> container and two 1-liter containers) for general minerals analysis The sample <br /> containers were filled to overflowing to eliminate headspace and to prevent volatile <br /> organics from coming out of solution The water sample containers were labeled, <br /> double-bagged in plastic bags, entered into a chain of custody form and placed on <br /> ice in a portable cooler The samples were delivered the same day in a chilled <br /> condition with the chain of custody to the laboratory for analyses No indications <br /> of contamination such as odor or sheen were observed during sampling Sampling <br /> was performed under the oversight of Steven Sasson of the SJCPHS <br /> 7.4.1 Groundwater Sample Analytical Results <br /> The groundwater samples collected from monitoring wells MW-1, MW-2 <br /> and MW-3 were analyzed for TPH calibrated as hydraulic fluid in <br /> accordance with modified EPA Method 8015 All analyses were conducted <br /> by Curtis & Tompkins in Berkeley, California Detailed laboratory <br /> analytical results with QA/QC documentation are provided in Appendix 1X <br /> The laboratory analytical results did not detect TPH as hydraulic fluid in <br /> the samples analyzed Specific sample data are as follows <br /> CRC Environmental Risk Management inc Project k 3620-001.4 <br /> George Bravante Receiver 2233 Grand Canal Boulevard <br /> January 19 1995 12 Stockton California <br />
