KLE/NFELOER ' <br /> 4) In late November 1999 , three deep groundwater monitoring wells were <br /> installed within the nursery property. The purpose of the wells was to evaluate <br /> groundwater quality of the first aquifer beneath the site at a depth of approx. <br /> 150 feet below grade. The reason for evaluating the deeper groundwater was <br /> to evaluate the potential for the nursery to be impacting the drinking water <br /> wells on the nearby Dodge and Eason properties north of the nursery. Since <br /> that time the monitoring wells have been developed , surveyed , purged , <br /> sampled and monitored . Reports documenting those findings are in the <br /> process . In general , groundwater flow on both December 28, 1999 and <br /> March 21 , 2000 was calculated to be 0 . 003 feet/foot to the southwest. This <br /> flow direction matches the San Joaquin County Flood Control and Water <br /> Conservation District data detailed in Section 2.4.4 . No obvious impact of the <br /> nursery's operations on deep groundwater quality was noted . The report for <br /> this installation and monitoring is forthcoming . <br /> In a March 31 , 1999 proposal , Kleinfelder documented the proposed installation of three deep <br /> monitoring wells on site . The assessment was requested by Mr. Rudy Schnagl of the State of <br /> California Central Valley Regional Water Quality Control Board in a letter dated February 26 , <br /> 1999 and subsequent correspondence dated May 28 , 1999 and September 20 , 1999 . The <br /> proposed scope of work was modified in Kleinfelder's work plan addenda dated July 1 , 1999 <br /> and August 26 , 1999, based on Mr. Schnagl's comments. In late November 1999 , three deep <br /> groundwater monitoring wells were installed on the property. The results of that work were <br /> detailed in Kleinfelder's " Deep Groundwater Assessment, Norman 's Nursery, . . . ," dated August <br /> 25 , 2000. That report stated the following : <br /> Based on the information obtained during this assessment as well as the ongoing monitoring <br /> of deep groundwater, the shallow perched groundwater and surface water, the following <br /> conclusions and recommendations were made. <br /> 1 ) In late November 1999, three deep groundwater monitoring wells were <br /> installed within the nursery property. The purpose of the wells was to evaluate <br /> groundwater quality of the first aquifer beneath the site at a depth of approx. <br /> 150 feet below grade. The reason for evaluating the deeper groundwater was <br /> to evaluate the potential for the nursery to be impacting the drinking water <br /> wells on the nearby Dodge and Eason properties north of the nursery. Both <br /> properties have production wells with water in the general range of 100 mg/I <br /> (parts per million) nitrate as nitrates which is equivalent to approximately 22 <br /> mg/I nitrate as nitrogen . The monitoring wells have been developed , <br /> surveyed , purged , sampled and monitored . The monitoring dates for said <br /> deep groundwater (DP- 1 through DP-3) were monitored on December 28, <br /> 1999 , March 21 , 2000, April 26 , 2000, May 22 , 2000, and June 21 , 2000. <br /> Quarterly reports have been issued documenting those findings . In general , <br /> groundwater flow on all five monitoring events was consistently calculated to <br /> be 0 . 003 feet/foot to the southwest. This flow direction matches the San <br /> 117226.
