Several previous monitoring reports state that the <br /> reported groundwater flow direction may not be an accurate representation of the true groundwater flow <br /> direction beneath the site, because water levels in wells MW-2 and MW-3 are influenced by their close <br /> proximity to nearby ponds. If the monitoring well network is not providing an accurate definition of <br /> groundwater flow direction, there is no way to compare downgradient versus background conditions, <br /> which is necessary in order to determine if degradation has occurred. Therefore, the monitoring network <br /> is inadequate, and Canandaigua Wine Company must install additional groundwater monitoring wells. <br /> By 25 November 2003, Canandaigua Wine Company shall submit the name of the California Registered <br /> Professional that will prepare the report described below. <br /> By 25 January 2004, Canandaigua Wine Company shall submit a Groundwater Monitoring Well <br /> Installation Workplan that describes an expanded monitoring network at the Turner Road Vintners site. <br /> The workplan shall be prepared by a California Registered Engineer or Registered Geologist and shall <br /> comply with the enclosed document,Items to be Included in a Monitoring Well Installation Workplan <br /> and a Monitoring Well Installation Report of Results. In addition, the workplan shall include a brief <br /> description of the activities at the East Facility. If those activities include the discharge of wastewater to <br /> land, then the workplan shall also propose the installation of groundwater monitoring wells at that site. <br /> If you have any que'sttiionns, please contact Tim O'Brien at (916) 255-3116. <br /> WE"� <br /> ELS;ChJief <br /> Waste Discharge to Land Unit <br /> Enc: Items to be Included in a Monitoring Well Installation Workplan <br /> cc: Mike Huggins, San Joaquin County Environmental Health Department, Stockton <br /> California Environmental Protection Agency <br /> Cti Recycled Paper <br /> The energy challenge facing California is real.
