Box 440 <br /> Lodi, CA 95241 <br /> CONDITIONAL APPROVAL OF GROUNDWATER MONITORL'VG 1YORKPL4N, EAST-SIDE <br /> WINERY; LODI, SAN JOA QUIN COUNTY <br /> I have reviewed the "Monitoring Well Installation Workplan, " prepared by Fall Creek Engineering, <br /> dated 26 June 2000. The plan was prepared in response to Regional Water <br /> azell correspondence ed <br /> 19 May 2000 requesting installation and sampling of groundwater monitoring <br /> ponds. <br /> After reviewing the workplan, I have the following comments: <br /> • Two groundwater monitoring wells will not allow calculation of the groundwater flow direction and <br /> are not sufficient to monitor the wastewater pond locations. Please resubmit the figure with wells <br /> placed to determine water quality upgradient and downgradient of the wastewater ponds. <br /> • Limit bentonite content in the cement/bentonite slurry to less than five-percent by weight to prevent <br /> excessive shrinkage. Grout placed below standing water in the borings must be placed using a <br /> tremie pipe placed at the bottom of the interval to be grouted. <br /> • Well development shall be performed no sooner than 24-hours after the well grout(cement/bentonite <br /> slurry) has been installed in accordance with the Department of Water Resources California'Well <br /> Standards, Bulletin 74-90. This is considered especially important to protect the surface seal of the <br /> wells. <br /> • The list of analytes groundwater samples will be chemically analyzed for was not specified, the <br /> analysis shall be consistent with Monitoring Program 58-539. A copy of the monitoring and <br /> reporting program is attached to this letter. <br /> • Permits from the San Joaquin County Environmental Health DepartmW01� 1�ZlV ,� , <br /> of groundwater monitoring wells. .li / <br /> If conditions in the borehole allow, It is recommended tht th <br /> the bentoniteat seal.
