r <br /> Working To Restore Nature <br /> linear component includes effects related primarily to well construction, particularly friction loss ' <br /> through the well screen slots <br /> 1 <br /> On the plot in Appendix II, the linear constant "B" equals 0.24 and the non-linear head loss <br /> constant "C" equals 0.045. With these data, sustainable drawdowns can be estimated for various <br /> times and pumping rates At a pumping rate of 3 gpm approximately 36% of total drawdown <br /> ' is attributable to turbulent flow. It should be noted that the well productivity (specific capacity) <br /> decreases with increasing time and discharge rate <br /> r <br /> The step drawdown test indicated high well capacity as evidenced by minimal drawdowns <br /> ' measured during the tests A rate of 3 gpm was selected for the longer term constant rate test <br /> as this was near the maximum capability of the pump <br /> 1 <br /> 5.2.3 Constant Rate Test <br /> Well MW-4 was tested at a constant discharge rate of 3 gpm Monitoring wells MW-1, MW-2, <br /> MW-5 and MW-8 were utilized as observation wells. <br /> During pumping, the water level in the pumping well was monitored on a regular basis as were <br /> rthe levels in the four observation wells. The maximum drawdown in pumping well MW-4 was <br /> ' 1.12 ft. No induced drawdown was distinguishable in any observation well during the test. <br /> Fluctuations in groundwater elevations in the observation wells have been attributed to naturally <br /> occurring changes within the aquifer. <br /> r <br /> ' The pumping test was concluded after 4 hours when stabilization of the water Ievel followed by <br /> aquifer recharge was observed in the pumping well. <br /> r <br /> i <br /> 1 I <br /> 150038UUTOR'i'S1CAP-0754 DRF 7 <br /> 1 <br />
