Page 5 <br /> Monitoring Well Installation Work Plan <br /> Appendix A <br /> L Project No.253.2 <br /> February 3, 1995 <br />. installing 100 pounds of granular bentonite that will be hydrated with tap water and be allowed to <br /> expand for a period of one hour. In the remaining annulus,neat cement grout will be installed using <br /> a slurry pump and tremie pipe. <br /> The well will be secured with a water tight locking cap encased within a traffic safe well box. A well <br /> construction schematic is attached as Figure 3. <br /> Relative well collar elevations may be surveyed by a competent surveyor. <br /> 2.10 Monitoring Well Development' <br /> Within 48 hours of well instaIIation after well sealing materials have had time to set,each monitoring <br /> well will be developed by mechanical surging and.pumping until a clear stream is obtained. All <br /> y down hole equipment will be decontaminated before and between uses. Development water will be <br /> removed from the well using either a bailer or a submersible pump and containerized in D.O.T. <br /> approved drums (labeled contents under analysis) to await proper disposition. After development <br /> the wells will be allowed to stabilize before they are purged and sampled <br /> II <br /> i <br /> f <br /> i <br /> i <br /> f <br />
