The test of Well #2 (512748) produced an average transmissivity value of 15,000 ft2/day as being representative of aquifer properties in the area of the well field for the capture zone analysis. The aquifer showed a slightly leaky response in the short term test which could not be seen in the twenty- four hour test because of the distance of the observation well from the pumping well, change in pumping rate during the pumping phase, or cycling of the pumping well during the recovery phase. Analysis of the short term test shows a transmissivity of690 ft2/day and a leakage factor of 0.25. This apparent increase in transmissivity with time or distance is consistent with a leaky response and corresponds with the conceptual model of a confined aquifer in contact with leaky confming layer(s). The resistance ofthe overlying confming material in the Centerville area is calculated as 2,950 days. Problems with the Analysis Problems in the test were presented by the variable pumping rate, interference of wells cycling on and lack of access to the pumped well. Analysis of the data did not present significant problems. References: Fetter, C. W. (1988) Applied Hydrogeology, 2nd. Ed., Merrill Publishing Co., Columbus, Ohio, pp 172 - 174. Jacob, C.
