WM <br /> rte= <br /> Union Ice Company- Weber Strect <br /> Phase II-Report of IYndings <br /> Page 7 <br /> s <br /> Since there is only one monitor well that is screened in the Sand 2 aquifer, we do not <br /> !. know a gradient direction for it. <br /> AQUIFER PROPERTIES <br /> A 12 hour pump test was conducted at Monitor Well Nlw-8S on March 2, 1991. The <br /> well was pumped at a constant discharge of 4.16 gpm for 12 hours, Discharged waters <br /> were stored in a !0,000 gallon swing tank on site;. <br /> t <br /> Water levels were monitored at two minute intervals for the first i0 minutes l t e test; <br /> five minute intervals from 10 to 60 minutes into the test; 10 minute intervals from 50 <br /> to 120 minutes into the test; 20 minute intervals from 120 to 180 minutes into the test; <br /> 30 minute intervals frons 180 to 240 minutes into the test, and 60 minute intervals from <br /> 240 to 720 minutes into the test. This sequence was then repeated while recovery levels <br /> were monitored for 12 hours after the pump was turned off. Similar monitoring <br /> intervals were observed for tile-observation wells on the property. <br /> The results of the pump lest were analyzed graphically using the Thies time - <br /> drawdown (log - ), Jacob straight line, time - drawdown (log - semilog) and Jacob <br /> straight line, residual drawdown (log - semilog) methods. The graphical solutions are <br /> i presented in Appendix C.
