Working To Restore Nature drawdown at 50 minutes elapsed pumping time for each test was used to calculate well productivity in gpm per foot of drawdown (gpm/ft) The reciprocal of productivity, specific drawdown (ft/gpm), is plotted versus the pumping rate for the three short-term tests on Plate 2-PT This plot is discussed in further detail in the following sections The long-term test entailed pumping approximately 980 minutes (16 hours)while monitoring drawdown to wells MW-6, MW-7, and MW-11 At the end of the pumping period, the complete recovery of well PTW-1 was monitored Semilog plots of the drawdown versus time for wells PTW-1, MW-6, and MW-7 are shown in Plates 3-PT, 4-PT, and 5-PT Data from well MW-11 were not plotted because no drawdown was observed The recovery data for well PTW-1 is plotted versus the log of time on Plate 6-PT, and a plot of the pumping rate during the long-term test is shown on Plate 7-PT Background Water Level Monitoring The static monitoring component of the test program consisted of placing a single channel data logger and transducer into well PTW-1 for approximately 65 hours before initiating pumping These data which are plotted on Plate 1-PT show a linear rate of water elevation decline of approximately 0 0018 ft/hr This translates to a decline of approximately 12 feet per month which probably represents the local seasonal trend Due to the small rate of decline, it was not necessary to correct the data for this effect Test Results: Short-Duration Test The short-term constant-rate tests showed a decline to well productivity (pumping rate/ft of drawdown) with increasing discharge rate The specific drawdown s/Q (feet of drawdown/gpm) is plotted versus the pumping rate (gpm) for the 2 3 and 4 5 gpm short- term tests and the 3 50 gpm longer-term test on Plate 2-PT The data from the first pulse test were excluded because the well underwent some additional development during the 5 gpm test The data plotted on Plate 2-PT were used to evaluate the well performance The drawdown in a pumped well consists of two components, the aquifer losses and the well losses The aquifer losses are generally related to laminar flow conditions and vary linearly with the pumping rate The well losses include head loss which varies both linearly and non-linearly with well discharge rate The linear well losses are generally related to aquifer damage during well construction The non-linear (non-darcy) well losses are related to turbulent flow within the well screen, the discharge pipe, and the formation • 38032-10
