J. H. KLEINFEZDER &ASSOCIATES <br /> A completed copy of the analytical rasults and the chain—of— <br /> custody form are included in Appendix B of this report. <br /> 4.5 MONITORING WELL ELEVATION SURVEY <br /> Tree relative elevations of the top of the four--inch PVC casings <br /> were surveyed for all seven monitoring wells on September 27, <br /> 1936 by L.J. Oliveira -- RCE 15949. The casing elevations were <br /> tied into an assumed elevation of 100 feet for the south east <br /> corner of the cement fermentation tank pad (as shown on Plate <br /> Nos. 7 and 8, Appendix A) . <br /> Depth to the static ground water table was measured from the top <br /> of each PVC casing on October 9, 1986 . The depth to water was <br /> - then subtracted from the elevation of the top of the well casing <br /> to provide a relative water table elevation for each monitoring <br /> well location. Plotting the water table elevations at each <br /> monitoring well location shows a general local ground water <br /> gradient to the south—southeast. (Plate No. 7, Appendix A) . <br /> 4.6 SHALLOW AQUIFER PUMP TEST <br /> On October 9 and 10, 1986, an aquifer pump test was performed at <br /> the Guild Winery facility. Monitoring well NW-7 was continuously <br /> w pumped at a discharge rate of 20 gallons per minute for 18 hours . <br /> Drawdown in the pumping well, MW-7, and the two closest <br /> -----------.--_--- .----------o.bser.vation--_wells-,.----.MW-4_-and _MW.-1_,_.—_were..__monz-tored at appropriate---- ----_'-- --- _ --- --_ — <br /> time intervals during the test. Discharge was measured and held <br /> constant by means of a piezometer attached to the discharge hose. <br /> �. 19:531 9 1Vp'�1 1 <br />
