ASE <br /> Eastside Winery,Lodi,San h0quin Co. <br /> Monitoring Well Installation Report <br /> adjacent seepage pond. At each well,the pumping started at the water table and <br /> continued until the water was visibly clear,then the pump was lowered in one <br /> foot intervals,pumping each interval until the water cleared. Next,the pump was <br /> rapidly raised and lowered in one-foot intervals to surge the screen. Each interval <br /> was pumped until clear and then the next higher interval was treated similarly. <br /> Finally,the well was pumped from near the water surface for 30 minutes after it <br /> was apparently clear. The total volume of water pumped from each well <br /> exceeded 1500 gallons. This corresponds to about 200 well volumes from wells 1 <br /> and 2 and about 100 well volumes from well 3. <br /> There was no change in water level associated with developing well 1. The level <br /> in well 2 rose about 10 inches after developing. At well 3,the level declined <br /> about 2 inches. <br /> C. Well Surveying <br /> Reference point elevations and coordinates were determined by Delta Surveys, <br /> 1115 Black Diamond Way,Lodi,CA 95240,a licensed civil engineer. The <br /> reference point elevations refer to the tops of the PVC casings;the bench mark <br /> elevation used was USGS San Joaquin County No. U1106. The horizontal <br /> coordinates follow the convention that positive X is to the east and positive Y is <br /> to the north. The data are: <br /> Well Reference Point Y Coordinate X Coordinate <br /> Elevation <br /> 1 52.19 -590.70 -1269.07 <br /> 2 59.99 -803.35 -574.60 <br /> 3 151.07 0 0 <br /> D. Water Sampling <br /> The wells were sampled for analysis on 18 August 2000. The details of this <br /> exercise and the laboratory findings are presented in a separate report. <br /> Please call me at(530)756-228 uestions you may have concerning the <br /> installation of these monito &S 810* <br /> � <br /> �p ��® ARIN�P <br /> Q <br /> Sincerely yours, ca p <br /> co rn <br /> V r Z <br /> `D o.
