RULE 2 - PERMITS <br />• the water -level recovery. The constant -head method used at wells COV23 and CWU23 <br />consisted ofshutting in the wells and allowing the heads to reach static pressure, then <br />opening each well and measuring the rate of flow over time. During the tests, water levels <br />were measured at approximately logarithmic time intervals, starting with an interval of 0.5 <br />second, using a pressure transducer and data logger. The flow rates during the tests of <br />wells COV23 and CWU23 were measured at approximately logarighmic time intervals, <br />starting with an interval of 0.5 minute. The test data were analyzed using test analysis <br />spreadsheet templates developed by the U.S. Geological Survey (Halford and Kuniansky, <br />2002). Hydraulic conductivities were calculated by dividing the transmissivity values by <br />the saturated thicknesses. Saturated thicknesses used for the calculations were based on <br />the length of well screen, open hole and /or filter pack at each well and the lithologies in <br />those intervals. Table 2.04.7 -T1 lists screened interval depths, and Exhibit 2.04.7 -E1 <br />contains well construction diagrams. The 2009 aquifer test output is presented in Exhibit <br />2.04.7 -E1, Hydrologic Information. Aquifer test results are also presented in the literature <br />for the overburden, underburden, and spoils aquifer near the PSCM (Williams and Clark, <br />1994) and for those and other units in the general area (Robson and Stewart, 1990). <br />PSCM Permit App. 2.04 -47.1 Revision 03/05/10 <br />
