Drawdowns were adjusted prior to plotting using the Jacob <br />(1963) method because significant pumping drawdowns occurred. Calculated <br />transmissivlties for the aquifer using this method vary from 5,720 to 8,689 <br />gallons per foot per day (gpf/day). Calculated storage coefficients range <br />from 0.0023 to 0.0058. Adjustments to initial drawdowns on the log -log <br />graphs were performed due to initial pumping rate flucuations. These <br />adjustments were calculated using the method of Cooper and Jacob (1946). <br />Based on aquifer tests conducted at this site, in our opinion an average <br />W transmissivity of 7,000 may be estimated. The cone of depression produced <br />during the constant -discharge test affected most of the site after <br />approximately 12 hours. The observation well furthest from MW -14 (MW -8) <br />was influenced after pumping for approximately 10 minutes at a 26 gpm rate. <br />
