s <br /> 1 <br /> Technical Summary & Report of 4TH Qtr Monitoring April 2, 1992 . <br /> Diamond Walnut Growers, 1050 South Diamond Street, Stockton, CA W0564 ' <br /> • The well logs for the City wells indicate they are completed in a significantly deeper <br /> zone than the shallow on-site monitoring wells and that the two zones are separated by <br /> ' at least 50 feet of clay rich material. As such the deeper wells probably do not represent <br /> a background level for constituents present in the shallow zone. It should be noted that <br /> significant variations in recorded levels have occurred in samples from each zone. <br /> 1 <br /> 6.0 RECOMMENDATIONS <br /> Successive sampling rounds have indicated the level of chromium species in well MW-3 is at <br /> or below the MCL. Wells MW-1 and MW-2 have remained consistently well below the MCL. <br /> A single additional sampling round is warranted to confirm the low levels of hexavalent <br /> ' chromium in MW-2. If the concentrations are below State MCL's a request for closure of the <br /> underground vaults and permission to abandon the monitoring well will be submitted. <br /> 1 <br /> 1 � <br /> 8011792 SAY 7 <br /> 1 <br />
