contamination is present in the vicinity of MW-2A and that groundwater contamination is not present south <br /> (up gradient)of the farmer 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 2003 <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-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-5,MW-6, <br /> MW-7, and MW-9(Figure 1-1)on June 10,and 11,2003 An equipment blank water sample,a duplicate <br />' water sample, and a sample from the holding tank were also collected for analysis Groundwater sampling <br /> field data sheets for the monitor wells are presented in Appendix B <br /> Prior to well purging, water levels were measured in all wells on June 10, 2003 to collect data for <br /> potentiometnc contouring The standing water volumes within wells scheduled for sampling were calculated <br />' using water levels measured in each well at the time of sampling and total well depths A submersible pump <br /> attached to a disposable discharge hose was then lowered into the well and used to purge three well casing <br />' volumes from each of the 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 /> I <br /> L1PRO]ECPSISAN]OQ1"SA1IQ03R11T WPD 2 <br />
