CAMBRIA ANTICIPATED FOURTH QUARTER 2001 ACTIVITIES Groundwater Monitoring Blaine will gauge and sample the site wells according to the existing sampling schedule and tabulate the data Cambria will prepare a groundwater monitoring report Groundwater Remediation GWE will continue on a twice-monthly basis Onsite Abandoned Water Well As previously proposed, Cambria would like to properly destroy the water well at this site We will proceed with well destruction activities once we have received approval from SJCPHS CONCLUSIONS AND RECOMMENDATIONS MTBE concentrations this quarter are within the historical norm for this site Groundwater flow direction was to the northeast again this quarter as it typically is, last quarter being an exception Cambria recommends the onsite water well be properly destroyed as it is not in use and there are no plans to use this well in the future Due to the location of the well and constraints of adjacent site features it may not be possible to access the well with a drilling rig Therefore we feel that pressure-grouting this well is the best alternative for well destruction Cambria sent photos of the well to SJCPHS to illustrate the logistical difficulties the location of this well presents We will submit a pernut for well destruction once we receive approval from SJCPHS to proceed with well destruction During Cambria's sensitive receptor survey for this site (November 2, 1999 report) we discovered a Department of Water Resources Water Well Drillers Report indicating a water well exists at the nearby Chevron site located at 3775 Tracy Boulevard We reported this information to SJCPHS and Chevron and to date we have not been given a definitive answer as to whether or not the well still exists It is important to determine the status of this well in order to protect it as a sensitive receptor or to properly destroy it to eliminate a possible conduit to deeper water bearing zones 0813 2
