Laboratory analyses detected no petroleum hydrocarbon constituents in the sample collected <br /> from well DW There have been consistently no detectable petroleum hydrocarbon analytes in <br /> DW since it was first sampled on December 20, 1999 <br /> Analytical results are summarized in Table 1 Laboratory reports and chain-of-custody <br /> documentation are presented in Appendix B <br /> GEOT ACKER DATA UPLOAD <br /> The depth to water data was submitted electronically to the State Water Resources Control Board <br /> (SWRCB) Geotracker database (confirmation number 6023975968) and the laboratory data was <br /> also submitted electronically to the SWRCB Geotracker database (confirmation number <br /> 5411013424) The facility has been assigned a Geotracker global identification number <br /> T0607700821 Documentation of the data submittal is contained in Appendix C <br /> CONCLUSIONS <br /> The nondetectable concentrations of petroleum hydrocarbon constituents in DW appear to be <br /> generally consistent with historical data <br /> The upper most groundwater table elevation has decreased over 7 5 feet in the monitoring wells <br /> since sampling began in June of 1999 MW1, MW2 and MW3 are not currently dry, and <br /> groundwater gradient and direction in the uppermost aquifer beneath the site have been <br /> reestablished The depth to water measurement in the domestic well DW indicates an increase in <br /> groundwater elevation of 4 24 feet since last monitoring occurred on January 14, 2005 This is <br /> apparently due to seasonal fluctuations and dewatering for crop irrigation or other groundwater <br /> uses <br /> i <br /> S 1148851reportsl2gtr2005 doc 4 <br />
