AZURE ENVIRONMENTAL <br /> July 30, 1997 AZ145-001 <br />' <br /> QUARTERLY GROUND-WATER MONITORING REPORT <br />' April 1 through June 30, 1997 <br /> Manna Pro Facility <br /> Stockton, California <br />' 1.0 INTRODUCTION <br />' This Quarterly Ground-Water Monitoring Report is submitted on behalf of Manna Pro <br /> Corporation ("Manna Pro") for the facility at 4004 South El Dorado Street in Stockton, <br /> California("the Site",Figures 1 and 2) ,This report presents the results of ground-water <br />' monitoring performed at the Site for the period of April 1 through June 30, 1997 This report <br /> also contains a technical status summary of the work completed at the Site during the quarterly <br /> period and work anticipated to be performed during the July through September, 1997 quarter <br />' 2.0 DESCRIPTION OF GROUND-WATER MONITORING PROGRAM <br />' The ground-water monitoring program at the Site consists of the following activities <br /> Quarterly collection of ground-water level measurements from monitoring wells <br />—'" * Quarterly and semi-annual collection and laboratory analysis ofground-water samples from <br /> monitoring wells, in accordance with the monitoring schedule to Table 1 <br /> O Quarterly submittal of ground-water morutonng reports <br />' 3.0 GROUND-WATER MONITORING RESULTS <br /> 3.1 Ground-Water Elevations and Flow Direction <br /> Water-level measurements and calculated ground-water elevations were collected from <br />' monitoring wells at the Site on May 27, 1997 and are summarized in Table 2 Ground-water <br /> elevations from Site monitoring wells were used to construct potentiometric contours for shallow- <br /> zone sediments A water table elevation map for the shallow ground-water zone is illustrated in <br />' Figure 3 <br /> Ground-water level data indicate the depth to ground water measured in on-site wells on May 27, <br />' 1997 vaned between 28 81- and 30 74-feet below grade These data indicate ground-water levels <br /> at the Site generally decreased compared with water levels measured during the previous quarter <br /> (average decrease of 0 4 feet) During the period between October 1992 and May 1997, the <br />' depth to ground water vaned between 42 60 feet (October 1992) and 29 11 feet (May 1997) <br /> below grade at well MW-1 Based upon these data, it appears that water levels at the Site have <br /> risen approximately 13 5 feet dunng the period between October 1992 and May 1997 <br />' 1 <br />
