' (up gradient)of the former USTs The fourth quarter of Phase N groundwater mg was sampling completed in <br /> May 1997 The CAP was submitted to EHD in January 1998 <br /> Quarterly groundwater sampling has been conducted since 1996 This report 1s the first quarter 2003 <br /> groundwater monitoring report which represents the third report in the current fiscal year groundwater <br /> sampling effort and presents the results of continued groundwater sampling following the schedule presented <br />' in Table 1-1 <br /> Table 1-I <br />' Sampling Schedule <br /> Quarter Monitor Wells to be Sampled <br /> First MW-2, MW-2A and MW-9 <br /> Second MW-2, MW-2A, MW-3A, MW4, MW-6, MW-7 and MW-9 <br /> Third MW-2, MW-2A and MW-9 <br />' Fourth MW-2, MW-2A, MW-3A, MW-4, MW-5, MW-6, MW-7, and MW-9 <br /> 2 0 FIELD SAMPLING SUMMARY <br /> Groundwater samples were collected from monitor wells MW-2,MW-2A,and MW-9(Figure 1-1)on March <br /> 25, 2003 An equipment blank water sample, and a sample from the holding tank were also collected for <br /> analysis Groundwater sampling field data sheets for the monitor wells are presented in Appendix B <br />' Water levels were measured in all wells on March 25 2003 to collect data for potent:ometric contouring The <br /> standing water volumes within wells scheduled for sampling were calculated using water levels measured in <br /> each well at the time of sampling and total well depths A submersible pump attached to a disposable <br /> discharge hose was then lowered into the well and used to purge three well casing volumes from each of the <br />' monitor wells <br /> At the beginning and during the purge process,the temperature,pH,and specific conductance of the purge <br /> water were measured and recorded on a sampling data sheet The pump was then removed and a disposable <br /> bailer was lowered into the well for the collection of a groundwater samples for benzene, toluene, <br /> ethylbenzene,and xylene(BTEX),and for total petroleum hydrocarbons as gasoline(TPH-G)analysis The <br /> groundwater sample was transferred into 40 ml glass sample containers Sample containers containing air <br /> bubbles were discarded and recollected Sample containers were sealed in a plastic bag,placed with ice in <br /> an insulated chest, and logged on a chain-of-custody form for delivery to the analytical laboratory <br /> f <br /> i <br /> LTROMC1S1SANlO1,1RSA,IQ03RPT WPB 2 <br />
