Presented in this <br /> addendum are the analytical results from the most recent sampling of the <br /> gro+radwater monitoring wells installed previously at the Sebastlartl <br /> Vineyards site, located at 4614 West Turner Road, Lodi, California. <br /> Introduction <br /> In accordance with the August 3, 1989 letter from the California Regional <br /> Water Quality Control Board (CRWQCB) and the September 22, 1989 letter <br /> from the San Josquin County Environmental Health Division (SJCEHD), the <br /> ten existing groundwater monitoring wells and the primary supply well were <br /> resampled to obtain additional information regarding the groundwater <br /> contamination previously detected at the site. <br /> Sample Collection and Analysis <br /> The groundwater samples were collected by purging a minimum of three <br /> casing volun,es from each monitoring well prior to bailing the water <br /> samples. The primary supply well was purged for approximately five <br /> minutes by running the well's turbine pump at its normal operating rate <br /> into the plant's pressure tank. The primary supply well water sample was <br /> taken from a 1/4-inch sample port located at the wellhead. <br /> Monitoring wells MW-1, MW-3, and MW-6 were sampled on September 12, 1989. <br /> The samples were analyzed for total petroleum hydrocarbons/gasoline range <br /> (TPH/G) and benzene, toluene, xylenes and ethylbenzene (BTXE). Well <br /> locations are shown on Figure 1. On September 20, 1989, monitoring wells <br /> MW-1, MW-3, and MW-6 were sampled and the samples were analyzed for <br /> ethylene dibromide and organic lead. Monitoring wells HW-2, MW-4, MW-5, <br /> MW-7, MW-8, MW-9, and MW-10 were also sampled on September 20, 1989. <br /> These samples were analyzed for TPH/G and BTXE. The primary supply well <br /> was sampled on September 26, 1989 and analyzed for TPH/G and BTXE. <br /> Results and Discussion <br /> The TPH and BTXE analytical results for all samples collected from the <br /> groundwaL.sr monitoring wells are summarized in Table 1, This table also <br /> 11101 1C1I1ite l;.kl-R,V.Id,jkmwho C otd.w.i.CA 9i(170 QNs-615.1696 FAX 910.618.2R4' <br />
