Section No. 6 <br /> Revision No 1 <br /> Date January 13, 1992 <br /> Page 50 of 55 <br /> CPriQnY Thp data louver periodically records the time and pressure values <br /> and converts the pressure to height of water above the transducer <br /> The data logger/transducer will be calibrated according to the <br /> manufacturer's specifications Calibration will be verified by comparing the <br /> data-logger read-out to manually measured water levels The instrument will <br /> be calibrated for each well tested Water levels will be allowed to reach <br /> static equilibrium following the insertion of the transducer below the water <br /> Slug withdrawal tests will be completed by either utilizing the <br /> dedicated pumps previously installed for groundwater sampling purposes, <br /> temporarily installing a pump, or using a bailer to remove a predetermined <br /> volume of water Static water level measurements will be collected prior to <br /> the tests If a pump or bailer is lowered into the well, the water level <br /> --will be—al=lowed=to=equil-ibrate=prior-to=initiating=the-.test--Water=level <br /> measurements during the test will be measured in the same fashion as <br /> previously discussed All equipment will be thoroughly cleaned with steam or <br /> a liquinox soap solution followed by a triple distilled water rinse prior to <br /> each use All decontamination and instrument calibration procedures will be <br /> documented using the appropriate field forms - <br /> 6 9 4 Pumping Tests <br /> Pumping tests will be performed to determine the hydraulic <br /> characteristics of a given water-bearing unit Special details pertaining to <br /> pump tests including test duration, methods, data recording methods, and <br /> test objectives will be outlined in the work plan for each given task. <br /> 6-50 <br />
