Lithology <br /> alternates between sands and <br /> screen gravels and silty clay. The well <br /> was constructed with 0.020 inch <br /> slotted screen and#2/12 sand <br /> and performed well for 17 years. <br /> Proposed Well Construction CKG will duplicate this well <br /> • Depth to water 73-78+ feet below construction for MW-5R. <br /> ground surface <br /> • Total depth of well 85 feet <br /> • Well screen 20 feet <br /> • Screen sized at 0.02 based on fine <br /> sand and gravelly nature of <br /> subsurface material (as observed in <br /> MW-5) Screen interval will be <br /> • Sand filling annular space to a depth 20 feet <br /> of a minimum of 2 feet above the <br /> screen. <br /> • Sand size 2/16 which provides a <br /> wide range so that fines can be <br /> screened while allowing good flow. Depth togroundwater <br /> • Bentonite pellet seal, minimum of anticipated to be 73-78+ <br /> two feet above the top of sand feet below ground <br /> • Cement seal from top of bentonite surface <br /> to ground surface <br /> • Well finished in a locking traffic <br /> grade well box marked "monitoring <br /> well" <br /> • Ground surface sloped away from Total depth= 85 feet with cap <br /> the well. on the bottom <br /> Not to scale <br />
