1 <br />' The Bouwer and Rice method (Bouwer and Rice, 1976) was used for the slug test data analysis <br /> This analysis involves a plot of residual head (logarithmic scale) versus time (arithmetic scale) <br />' The straight line is applied to the early-time data, after discounting the effects of the gravel <br /> pack, and used to calculate a value for K <br />' Figures 1 through 3 depict the results of the straight line graphical analysis applied to the slug <br /> test data by the Bouwer and Rice Method Table 1 indicates the slug test results for K in <br /> feet/minute and the corresponding y-intercept on the graphical analysis The K values range <br />' from 0 00147 to 0 00217 feet/minute and are well represented for the formation around the <br /> screened zone being within literature values for silt and silty sand (Groundwater, 1979) <br />' TABLE 1 <br /> Aquifer Characteristics Test Results (10/30/91) <br />' San Joaquin County Human Services Agency Building <br /> Stockton, California <br /> Well ID k - feet/min k - cm/sec y - Intercept <br /> MW - 4 000147 7 47 x 10' 08554 <br />' MW - 6 0001497 7 61 x 10-4 1 48 <br /> MW - 8 000217 1 10 x 10.3 1 474 <br /> References <br /> 1 Bouwer, H and Rice, R C 1976 A slug test for determining hydraulic conductivity of <br /> unconfined aquifers with completely or partially penetrating wells Water Resources <br />' Research Vol 3, No 1, pp 263-269 <br /> Groundwater, Freeze R A, Cherry J A , Prentice Hall, Inc , 1979 <br />' Bouwer, H The Bouwer and Rice Stu Test An update, Vol 27 No 3 Ground Water, <br /> Slug - P > <br />' May-June 1988 <br /> 1 <br /> I <br /> Iarra,src wr 06101A2 <br />
