installed in the groundwater quality monitoring well from a depth of 5 feet above to 5 feet <br /> below the existing potentiometric surface. All screen/casing strings will be threaded together. <br /> The use of solvent glues will not be used to assemble the screen/casing strings. Filter pack <br /> material will be clean, rounded, water-worn material, and will be installed in the annular <br /> space adjacent to thl,well screen, to a distance of 2 feet above the top of the well screen <br /> section. Within the annular space above the filter pack material, a minimum 2-foot thick <br /> hydrated bentonite pellet seal will be placed. The remaining portion of the annular space will <br /> be sealed with a neat cement slurry to ground surface. To protect the monitoring well from <br /> accidental damage or tampering, a traffic-rated Christy Box with an internal locking cover will <br /> be placed over the top of the monitoring well. The top of casing elevation for the monitoring <br /> well will be determined using standard surveying methods. <br /> GROUNDWATER QUALITY MONITORING WELL DEVELOPMENT <br /> Following construction and installation, the groundwater quality monitoring well will be <br /> developed to improve the hydraulic conductivity between the filter pack and aquifer material. <br /> Well development will consist of mechanically surging the groundwater quality monitoring <br /> well with a vented surge block and bailing to remove material entering the groundwater <br /> quality monitoring well through the well screen as development operations proceed. <br /> Development operations will continue until groundwater bailed from the groundwater quality <br /> monitoring well is clear. <br /> iem oi�m.�x> Page 4 <br />
