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 will be surveyed by a licensed land surveyor. <br /> 2.10 114onitoring Well Development <br /> Within 48 hours of well installation 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 /> 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 t <br /> _ r <br /> l <br />
