} <br /> (up gradient)of the former USTs The fourth quarter of Phase IV groundwater sampling was 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 is the second quarter 2002 <br /> groundwater monitoring report which represents the fourth 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 1-1 <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, MW-4, MW-6, MW-7 and MW- <br /> 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,MW-3A,MW-4,MW-6,MW-7, <br /> and MW-9 (Figure 1-1) on June 25 and June 26, 2002 In addition, a duplicate water sample and an <br /> equipment blank water sample were collected Groundwater sampling field data sheets for the monitor wells <br />' are presented in Appendix B <br />' Water levels were measured in all wells on June 25,2002 to collect data for potentiometric 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 to the well and used to purge three well casing volumes from each of <br /> the monitor wells <br />' At the beginning and during the purge process,the temperature,pH,and specific conductance of theur e <br /> p g <br />' water were measured and was recorded on a sampling data sheet The pump was then removed and a <br /> disposable bailer was lowered into the well for the collection of a groundwater samples for benzene,toluene, <br /> ethylbenzene,and xylene(BTEX)and fortotal 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 /> VPROJECTS1SANJOQIHSA12QMPT WPD 2 <br />
