EXECUTION

3.01 All soil erosion controls shall be in place prior to start of work if drilling outside of Normal Operating Season (NOS) defined as May 15 to October 15.

3.02 The target depth to achieve sufficient water yield is estimated to be within 250 feet of the surface. The CONTRACTING OFFICER must approve drilling past the target depth. If the well yield is below the minimum desired, the CONTRACTING OFFICER shall consider approving further drilling beyond 250-ft or moving to a different drill site. If a sufficient amount of water quantity is obtained the CONTRACTING OFFICER may direct the CONTRACTOR to stop drilling prior to the 250-ft depth.

3.03 Final disinfection shall be sufficient to produce a minimum of 50 mg/l (parts per million) of available chlorine solution when mixed with the total volume of water in well.

3.04 Steel casing shall be used for the sanitary seal and extend 2-feet above ground surface. The finished well shall be secured with a lockable well cap.

Placement of slotted well casing shall be determined in the field.

PVC well liner casing shall not be extended above ground surface.

If a consolidated geologic formation exists below the sanitary seal, the CONTRACTING OFFICER shall consider not extending the steel casing to the bottom of the drilled hole.

3.05 Well development will be performed in manner that does not threaten or damage the well structure. The pump and prime mover shall have a capacity in excess of the anticipated lift and final production capacity of the well. The development and test pump shall be set to a depth in excess of the anticipated pumping level. Development equipment and method used shall permit variable pumping discharge rates.

SECTION 02525 - WATER SUPPLY WELLS (Continued)

3.06 Performance Pumping Test – After recovery from well development is complete, (return of well to static water level), a step-drawdown test and a constant rate test shall be conducted. Pumping the well at the design rate or at maximum yield for a period of not less than 24 hours, unless otherwise specified, and until the pumping level remains constant for at least 8 hours, or until the CONTRACTING OFFICER terminates testing.

3.07 Once well development, disinfection, and performance testing are complete, and all traces of disinfection have been removed the CONTRACTOR shall collect representative water samples. The CONTRACTOR will have a California certified lab conduct the following test analyses: General Mineral; General Physical; Inorganic Chemical; EPA method 200.8 for Arsenic, Boron, Vanadium; and bacteriological colilert analysis. Submit all results to the CONTRACTING OFFICER.

3.08 Well Destruction

Locate all existing underground utilities at or near existing abandoned well. All water utilities shall be capped and all electrical utilities shall be disconnected. Remove exposed unused utilities at least down to 2-feet below ground surface. Remove and dispose of casing down to 3-feet below ground surface.

Contractor shall remove and properly dispose off government land any existing surface grade concrete aprons or foundations surrounding well casing and any existing obstructions and contaminants from within the well casing. No disposal will occur on Government land.

Fill well from the bottom up. The maximum permissible vertical drop for concrete or other cementitious materials is limited to 2 feet. Cementitious material shall not be exposed to the action of water before setting, or deposited in water, except upon written permission. If placing cementitious material in water, prevent segregation by placing from the bottom of the hole using a slick line or equivalent allowing the cementitious material to displace water as the hole is filled.

Provide a continuous seal from the bottom of well to within 3-feet of ground surface. Sealing material placed in the well shall flow over to form a cap.

The CONTRACTOR must verify that the volume of the material placed in the well is at least equal to the volume of the hole. The CONTRACTOR will report results to the COR.

After well seal has been approved by the CONTRACTING OFFICER, existing native soil fill material shall be mounded 1-foot higher than the existing ground surface to allow for settlement. Grade fill material back to existing ground surface with a 1/2:1 slope
