The purpose of the deep borings is to collect <br /> discrete depth groundwater samples to evaluate the vertical extent of groundwater contamination at <br /> the site. The results of the investigation will be used in recommending the locations and depths of <br /> additional groundwater monitor wells, if warranted. <br /> ➢ Conduct a door-to-door investigation of properties in the immediate arta of the site to attempt to <br /> identify the presence of pumping wells in the site vicinity. A sensitive receptor survey (SRS) was <br /> conducted on November 20, 2002 (Groundwater Monitoring Report, Third Quarter 2002, dated <br /> January 16, 2003). No pumping wells were identified by the SRS, but Condor believes additional <br /> field reconnaissance and residential interviews regarding possible pumping wells is needed to verify <br /> whether or not pumping wells are influencing the groundwater gradient at the site. <br /> LIMITATIONS <br /> This report was prepared under the direct supervision of a Registered Geologist in the State of California. <br /> The standard of care for all services performed or furnished by Condor is commensurate with the care and <br /> skill ordinarily used by a member of the environmental profession practicing under similar conditions at <br /> the same time in the same locality.
