Section 4 <br /> Well Development <br /> Well development will consist of pumping and surging(using a disinfected surge block and rod). All <br /> equipment used for well development shall be cleaned and disinfected prior to introduction to the well. <br /> Pumping will continue until general water quality parameters stabilize including pH,electrical <br /> conductivity,and turbidity. During initial development, pH,electrical conductivity,and turbidity shall <br /> be monitored at least once each casing volume Once initial development is complete,where purged <br /> water is visually clear and pH and electrical conductivity have stabilized,development will continue <br /> until development water is less than 5 NTU measured at 5 to 10 minute intervals. Well development <br /> shall not be performed until a minimum of 72 hours after placement of the well seal. Development <br /> water will be discharged to land or in adjacent disposal ponds on-site. <br /> July 2015 Conformed with 21 October 2015 Conditional Approval 11 MW-5 Replacement <br /> Gty of Riverbank WWTF Monitoring Well Installation Workplan <br />
