r <br /> APPENDIX F: PUK TESTING PROTOCOLS <br /> 'i <br /> Aquifer pump tests wil}1 be performed on selected wells . mater levels <br /> in a well not expected1to be influenced by the pump tests will be <br /> measured for two days ,immediately before the pump tests are conducted . <br /> The day before the actual pump to ting , stepped drawdown tests will be <br /> run to evaluate the efyficiency ant maximum flow rate of each well and <br /> the most appropriate plumping rate for the tests . The step tests will <br /> i <br /> consist of pumping at an initial ate of 2 GPM for at least one-half <br /> F hour , and then increasiing the pum ing rate in uniform increments at <br /> is <br /> half-hour intervals . `'Atmospheric pressure data may be collected on <br /> site during the period; of well testing to help evaluate the barometric <br /> N <br /> efficiency of the aquifers . <br /> Drawdown in the pumping well . will be recorded at the selected time to <br /> allow predicting the maximum allowable test duration for each <br /> corresponding pumping .rate. Pump tests will consist of a pumping <br /> period , and recovery data will be collected until 90% of the drawdown <br /> has been recovered . Pumping rates will be selected based on the <br /> information collected ..from the stepped drawdown tests that a maximum <br /> radius of influence ca:n be achieved with maximum allowable drawdown <br /> within 12 - 24 hours of pumping. <br />
