To establish drawdown caused by pumping (air lifting) of the wells, <br />the beginning and ending water levels were measured. For supporting <br />information water levels were measured after pumping was stopped to <br />determine their recovery with time until pre-pumping conditions had <br />been achieved. Both the pumping and recovery data were analyzed <br />following the modified non-equilibrium formula of Jacob as presented <br />by Ferris et al. (1962). The solutions are shown on Exhibits 27 <br />through 32. Since recovery time and depths were used in the aquifer <br />test, the quantity of water pumped was corrected to illustrate recovery <br />recharge to the well. Using this corrected recovery rate, certain <br />inadequacies of the method of analysis can be eliminated, such as <br />errors introduced by casing storage and vapor loss. Drawdown water <br />discharge rates were also claculated to achieve a range of trans- <br />missivities inherent to the aquifers. The values of transmissivity <br />ranges for each aquifer test is summarized below. ~ d,~ <br />• <br />i . <br />p, ~ ~.~~% <br />WELL TRANSMISSIVITY , 0l4 <br />LC-2 0.10 GPD/Ft to 2.'42 GPD/Ft ~ ~o~ <br />LC-4 0.10 GPD/Ft to 6.92 GPD/Ft _ <br />UC-2 0.18 GPD/Ft to 5.20 GPD/Ft ~`~?~5\ <br />,~~~'~' ' , IS7 <br />.e ~ <br />-~ ~ ~ <br />~ ua~ ~~>~ <br />~.y <br />s <br />~e~~ <br />;~ <br /> <br />~~ <br />°'~ ~~=r <br />z <br />~r <br />~~ <br />40 <br />FT/~~.~ <br /> <br />
