DEL -TECH GeotechnA)''WO'p T, JH <br /> 93 JUN 17 PM I : 55 <br /> Lawrence Beasley <br /> APACHE PLASTICS <br /> 2050 East Fremont Street <br /> Stockton, Calif. 95205 <br /> RE: STATUS OF THE (7) MONITORING WELLS & (2) MANOMETERS ON-SITE. <br /> Mr. Beasley, <br /> On June 3, 1993 , Don Light of Del-Tech and Diane Hinson of the San Joaquin County <br /> Environmental Health Department inspected and monitored the nine locations referenced <br /> above, <br /> Uponreviewing the site' s data from previous events and researching the available data on <br /> surrounding sites, it now appears that the bottom of the wells are located slightly above the <br /> static water table. After the past year of substantial rainfall it is anticipated that recharge of <br /> the local aquifer will occur and therefore make these wells functional again. Monthly <br /> monitoring of these well locations would be beneficial in establishing the point in time when <br /> the wells become producing again. At that time levels and analysis can be accomplished to <br /> establish the gradient of the water table and if any concentrations of controlled substances are <br /> present, <br /> Thetable below is representative of the current conditions of each of these points. <br /> DEL-TECH GEOTECHNICAL SUPPORT/MONITORING WELL <br /> SUMMARY LOG / APACHE PLASTICS <br /> ?.las nl;:"rii. 1 ¢D!
