33 21 00 – 2

D. The Contractor shall furnish, install, and operate all necessary pumping equipment for development and testing purposes. The Contractor shall recommend the depth the pump shall be set; however, the setting must be approved by the Contracting Officer. The Contractor shall furnish all necessary discharge conduit for the pumping unit, which shall be sufficient size and length to convey the water being pumped to the point of final discharge as directed.

E. Contractor shall furnish, install, and operate equipment of approved size and type for measuring the flow of water; such equipment shall be a weir box, orifice, or water meter. To measure the elevation of the water level in the well, an air line, complete with gage, hand pump, and check valve shall be provided. Unless otherwise directed, the air line shall be securely fastened to the pumping unit, and shall terminate approximately at the maximum desired level, but in no case shall it be within 2 feet of the end of the suction pipe.

3.01 DRILLING

A. The type of drilling equipment used shall be determined by the Contractor.

B. A well hole of adequate diameter to receive a 5-1/2 inch diameter casing shall be drilled to approximately 40 to 60 feet depth at a locations approved by the Contracting Officer. Extreme care shall be exercised not to seal off or bypass any aquifers in the drilling process. When any water of a measurable amount is encountered, the well shall be bailed or test pumped to determine the amount of water available. The Contractor shall develop the water-bearing formation giving the desired amount of water unless otherwise instructed by the Contracting Officer.

C. Each well shall be drilled to conform, as nearly as practicable, to a true vertical alignment. In the event that the well is found unacceptable by the Government, due to crookedness or lost tools, the Contractor shall either correct the situation or abandon the well and drill a new well at no additional cost to the Government. The abandoned hole shall be adequately backfilled with compacted impervious material at no additional cost to the Government.

D. Daily log and record, for each well, all materials passed through and the depths at which the changes in the formations occur, together with such other information as may be called for by the Contracting Officer. The log of the well shall show all material penetrated and full descriptive notes made of everything found by the drill and of all difficulties or unusual conditions met in drilling. All water-bearing strata shall be described in special details as to whether the material is loose, compact, its color and, if gravel, whether it is water worn or angular. Upon completion of the well, the log shall be prepared in quadruplicate, signed by the Contractor, and

33 21 00 – 3 submitted for approval.

E. In the event of a dry hole, the Government reserves the right to have the Contractor drill another well at a negotiated price. The location will be in the proximity of the dry hole.

F. The abandoned well bore shall be plugged with impervious material as required by the State of Kansas, Department of Health and Environment. All salvageable materials recovered by the Contractor shall remain his property unless specifically purchased by the Government.

G. If, for any reason, the Contractor should abandon drilling at one location in favor of another or should fail to complete a satisfactory well bore as specified or required, he shall plug the abandoned bore as specified above at no cost to the Government and without compensation for drilling operations performed at the abandoned site.

Salvaged materials shall remain the Contractor's property.

3.02 PROTECTING WATER SUPPLY

A. The Contractor shall take precautions to prevent contaminated water, or water having undesirable physical or chemical characteristics, from entering the bore holes made by the Contractor in drilling the well. He shall also take all necessary precautions during the construction period to prevent contaminated water,gasoline, etc., from entering a well by seepage through the ground surface.

3.03 CORRECTIVE WORK:

A. In the event that a well becomes contaminated, or that water having undesirable physical or chemical characteristics does enter a well due to the neglect of the Contractor, he shall, at his own expense, perform such work or supply such casings, seals, sterilizing agents, or other materials as may be necessary to eliminate the contamination or shut off the undesirable water.

3.04 TEMPORARY CAPPING

A. At all times during the progress of the work, the Contractor shall protect the well in such a manner as to effectively prevent either tampering with the well or entrance of foreign matter into the well, and, upon completion, provide and weld a steel plate or cap to the casing head.

3.05 CASING

A. Placement: Perforated casing shall be placed opposite water bearing strata. The exact lengths and locations of the perforated sections shall be recommended by the

33 21 00 – 4

Contractor to produce the greatest quantity of water from the well. Watertight PVC casing shall be installed from a minimum of two (2) foot above the ground surface to the top of the production zone. The blank casing shall be installed in the well in lengths and locations as recommended by the Contractor and approved by the Contracting Officer. The Contractor shall use some mechanical centering device on casing at 20 feet intervals to keep the casing centered in the well hole. Casing installation and joint connections shall be installed in conformance with the manufacturer's recommendations, industry standards, and the State of Kansas Water Well Handbook/Application.

3.06 GRAVEL PACKING

A. Gravel pack: The space between the perforated casing and walls of the well hole throughout all aquifer zones shall be filled with Contractor-furnished, hard, select, water worn, washed gravel. The Contractor shall recommend the gravel size to the Contracting Officer after the hole is drilled and analyzed. The gravel shall be washed clean of all silt, dirt, and foreign material before placement in the well hole. The use of crushed rock will not be permitted. The well shall be swabbed and cleaned concurrently with the gravel packing operation. Gravel shall be disinfected immediately prior to or during placement. The gravel pack shall be installed in accordance with State regulations.

3.07 WELL DEVELOPMENT

A. After installation of casing and gravel pack, but before any final pumping tests have been started, the Contractor shall develop the gravel pack and adjacent aquifer by using one of the following methods:

1. Water-Jetting - Forcing water through the well screen into the aquifer with high-pressure nozzles to clean away foreign or fine material.

2. Surge Block - Using a wood or rubber block with flapper valve to surge the aquifer. Surging should start gently and gradually increase in force.

3. Surging with Compressed Air - May be used as alternate to surge block method.

4. Backwashing - Pumping water to the surface and then letting it fall back into the casing to produce a surging effect in the casing.

B. Development shall be conducted to give the maximum practical yield of water per foot of drawdown and to extract from the water-bearing formation the practical maximum quantity of such fine materials as may, during the life of the well, be drawn into the casing when the well is pumped under maximum conditions of

33 21 00 – 5 drawdown.

C. Additional gravel must be added as necessary to compensate for settling of the gravel material during the cleaning process.

D. At the conclusion of the development, the well shall be cleared of all accumulations of sediment to the full depth of the well.
