3.0 EXECUTION <br /> 3 . 01 INSTALLATION OF PUMPING EQUIPMENT <br /> A . The pump, flow measuring device(s) , discharge piping, access pipe/air-line, and other <br /> necessary appurtenances shall be installed for the well pumping test. <br /> 3 . 02 PRELIMINARY CAPACITY PUMPING TEST <br /> A . Run a preliminary capacity pumping test prior to the pumping tests . The preliminary <br /> capacity pumping test shall be conducted to establish rates and evaluate equipment <br /> performance, including discharge capacity, and to estimate the production capacity of <br /> the well prior to implementation of the step drawdown test. Operate the pumping test <br /> equipment continuously at such rates of discharge and for such period of time as <br /> determined by the ENGINEER. Duration of such preliminary test shall be <br /> approximately 1 hour. <br /> B . Unless otherwise approved by the ENGINEER, the preliminary capacity pumping test <br /> shall be conducted on the day preceding the pumping test . <br /> C . The static water level in the well shall be allowed to recover for a minimum time equal <br /> to the duration of the preliminary test before start of well pumping test or longer as <br /> determined by the ENGINEER. <br /> 3 . 03 PUMPING TEST <br /> A . Operate the variable-rate step-drawdown and aquifer performance pumping test <br /> equipment continuously at such rates of discharge and for such period of time <br /> prescribed by the ENGINEER. <br /> B . The CONTRACTOR shall provide an operator during the entire time the pump is in <br /> operation, as required by the ENGINEER, to operate the prime mover and to regulate <br /> the discharge by the throttling device during the test pumping period. <br /> C . The CONTRACTOR shall collect a water sample from the spigot on the discharge <br /> pipe between the 6th and 8th hour of the pumping and submit the sample to the selected <br /> laboratory for analysis of the following parameters : <br /> • Select primary drinking water standard listed in Chapter 62-550, F.A. 0 <br /> including inorganic compounds (Table 1 ) , volatile organic contaminants <br /> (Table 4), synthetic organic contaminants (Table 5), Total coliform , and <br /> radionuclides (Combined radium-226 and radium-228 and Gross alpha <br /> particle activitiy; <br /> • All secondary drinking water standards (Table 6) listed in Chapter 62-550, <br /> F.
