Box 280 <br /> Davis, CA 95617 <br /> RE-SURVEYING REPORT <br /> Thank you for submitting the Re-Surveying Report for the former Cal Farm Supply on West <br /> Washington Street, Stockton. During my review of the report I found that some numbers had been <br /> transposed for the March 1994 sampling event, and subsequently asked for additional information <br /> from your consultant, Kennedy/Jenks. The Request for Additional Information was received on 6 <br /> March. <br /> Four of the five monitoring wells were re-surveyed on 25 January 1995, and water level elevations <br /> were measured. Monitoring well #5 was not included in the survey because it was covered with <br /> standing water. I observed the surveyors, and feel confident in the data they generated. I asked <br /> Kennedy/Jenks to recalculate the groundwater gradient for the last four quarters of monitoring. The <br /> re-calculations do not show a major shift in gradient; however, per my request, Kennedy/Jenks has <br /> included the groundwater contour lines on the site maps. This gives a much better picture of the <br /> groundwater gradient, and lends to a better understanding of the site. <br /> During my review of the March 1994 groundwater data, I noticed that there are two Table 1's in the <br /> quarterly report dated April 1994. The groundwater elevations of MW2 and MW3 are different in <br /> each version of Table 1. In addition, the Re-Surveying Report switches the elevations of MWI and <br /> MW4 from those in the quarterly report. I asked Kennedy/Jenks for the original field notes to <br /> determine the actual values, but they have been unable to locate them. Due to the uncertainty of the <br /> data, T ll nG longer use any iruCru.atLor. generated during the March i994 sampling event. <br /> As we discussed during our meeting yesterday, I will be contacting you shortly with details about <br /> the additional plume definition and remediation which will be required by the Regional Board. If <br /> you have any questions, I can be reached at (916) 255-3104. <br /> WENDY WYELS <br /> Ag Regulatory Unit <br /> cc: Ms. Kelye McKinney, Kennedy/Jenks, Sacramento <br />
