Main Street, Manteca, California <br /> Quarterly Ground Water Sampling Report <br /> October, 1992 -January, 1993 <br /> I <br /> Narrative <br /> Scope of Work <br /> Water level measurements were taken monthly during the last quarter of 1993 In <br /> addition two samph ng events were carried out during the period covered by this <br />' report, one on November 4, 1992, and a second on January 27, 1993 <br /> Ground Water Sampling <br /> On November 4, 1992, '%T-IF Environmental Consultants, Inc, in conjunction with <br /> HK1vI, Inc , conducted field measurements, well pumping, and Sxnund <br /> water <br /> sampling on two ground water monitoring wells located <br /> at this site, MW-7 and <br /> I <br /> MW-8 The vapor extraction system installed and operating on MW-2 prevented <br /> sampling of this well <br /> Again, on January 27, 1993, WHF Environmental Consults-ns, Inc , in conjuction <br /> with Mvt Inc, conducted field measurements, well pumping, and ground water <br /> samplag on three ground waxer monitoring wells located at this site, MW-2, MW- <br /> 7 andMW 8 Vapor extraction system piping on MW-2 had been removed from <br /> the collar ofMW 2, so it could be sampled and water level measured <br /> 4 <br /> Ground water elevations were obtained from two wells prior to any well pumping <br /> activities Each of the wells was evacuated by means of a steam-cleaned, stainless <br /> I steel bladder-type Pump At least three well volumes of water teras removed from <br /> each of the wells prior to sampling so as to achieve stability in the well Stability <br /> was measured as the wells were being pumped by testing for pIi temperature, and <br /> electrical conductivity The samples were then taken using disposable teflon <br /> bailers <br /> IImmediately after they were collected, the samples were labeled and transported <br /> under chain of custody to Geo-Monitor Laboratories, a state certified lab <br /> Samples were transported in an ice chest containing both blue ice and crushed ice <br /> I as per the San Joaquin County requirements <br /> The samples were analyzed for purgeable aromatic hydrocarbons by EPA method <br /> 602 and TPH gasohne by LUFT method 5030 The analytes and concentrations <br /> are listed in Table 2 of this report <br />
