SECTION 5 - CONSTRUCTION

NOTE: Construction requirements vary according to type of formation, type of well, intended use. Please review the both the general requirements and Section 6, "SPECIAL WELL CONSTRUCTION TECHNIQUES" for the type of well you are working on.

5.1 LOCATION.

5.1.1 GENERAL. In establishing the location of a well the constructor shall give consideration to sources of contamination which exist on or adjacent to the premises where the well is to be located. As far as possible, the well shall be located on ground which is higher than sources of contamination and shall have ready access for repairs, maintenance, treatment and inspection.

5.1.2 RELATION TO SOURCES OF CONTAMINATION. Determination of minimum lateral distances to locate a well from potential sources of contamination involves evaluation of the character and location of the sources of contamination, types of geologic formations present, depth to the aquifer, effect on ground water movement by well pumping and possibilities of flooding of the site by surface waters. Based on practice and experience, accepted minimum lateral distances for some common sources of pollution with respect to a well have been established. The lack of specific distances for other possible sources of contamination such as streams, refuse disposal sites, excavations, waste treatment facilities, buried oil and gasoline storage tanks, improperly constructed wells and cisterns, etc. does not minimize their potential hazard. These must be evaluated in each particular situation and a distance arrived at based on the pertinent facts.

5.1.3 MINIMUM LATERAL DISTANCES. The following minimum lateral distances shall apply for common sources of contamination listed:

POTENTIAL SOURCES OF CONTAMINATION	MINIMUM LATERAL DISTANCES FOR CLAY AND LOAM SOILS.
Cess Pools	100 Feet
Leaching Pit	100 Feet
Pit Privy	100 Feet
Subsurface Seepage Tile	100 Feet
Manure Piles	100 Feet
Septic Tank	100 Feet
Sewers (Cast iron with water tight, leaded or mechanical joints)	50 Feet
Footing Drains (No connection to a sewer or a sump handling sewage)	10 Feet
Pump House Floor Drain (Cast iron with water tight joints and having free fall discharge to ground surface)	2 Feet

When the upper formations are more pervious, the lateral distances shall be increased (i.e., double the distance for highly pervious gravel formations).

5.1.4 FLOOD WATER. Locations subject to flooding should be avoided. If no reasonable alternate site exists, wells may be constructed in flood zones providing special protective construction is included.

5.1.5 VERTICAL CLOSED LOOP SYSTEMS/WELLS. Vertical closed loop systems and wells shall not be located closer than 50 feet to a septic tank, its field lines, or other water supply wells used for human consumption. This requirement may be waived. An approved waiver may be obtained by contacting the Commission Office by telephone or mail. Written approval must be obtained from the Commission prior to construction of the well.

5.1.6 OPEN LOOP SYSTEMS/WELLS. The location of open loop wells shall meet the same criteria as water wells used for domestic or human consumption.

5.1.7 VERTICAL CLOSED LOOP SYSTEMS/WELLS. Vertical closed loop systems/wells shall not be located closer than fifty (50) feet to a septic tank, its field lines, or other water supply wells used for human consumption. This requirement may be waived. An approved waiver may be obtained by contacting the Commission Office by telephone or mail. Written approval must be obtained from the Commission prior to construction of the well.

5.1.8 INDUSTRIAL AND IRRIGATION WELLS. No industrial or irrigation well shall be located nearer than one hundred (100) feet to any other well producing potable water. It is recommended that locations subject to flooding be avoided. If no reasonable alternate exists, wells should be constructed with the casing terminating two (2) feet above the maximum known flood water elevation.

5.1.9 RELATIONS TO BUILDINGS. With respect to building, the location of a well shall be as follows:

5.1.9.1 ADJACENT TO BUILDING. When a well must be located adjacent to a building, it shall be so located that the center line of the well extended vertically will clear any projection from the building by not less than ten (10) feet. The well shall also be located at least ten (10) feet away from any power lines.

5.1.9.2 INSIDE BUILDING. The casing top of a well and any other opening shall not terminate in the basement of any building, or in any pit, room or space which is below ground surface or connected to a basement, which is not properly drained or pumped. Where it is necessary to seal out seep water or rain water in small diameter wells that are underground, National Water Well Association approved pitless adapters, or an approved seal, shall be used.

5.2 DESIGN FACTORS. The design of each well shall include consideration of the following:

5.2.1 NATURAL PROTECTION. Location of the well shall include utilization of every natural protection available to promote sanitary conditions.

5.2.2 UNDESIRABLE GEOLOGICAL FORMATIONS. The exclusions of water bearing formations which are or may become contaminated formations which have undesirable characteristics.

5.2.3 DURABILITY. The use of construction methods and materials which will result in a durable well producing safe water, without excessive sediment and sand, or harmful bacteria.

5.3 MATERIALS AND TECHNICAL REQUIREMENTS.

5.3.1 CONSTRUCTION WATER. Water used in the drilling process should be obtained from a source which will not result in contamination of the well. It is required that an appropriate amount of chlorine solution be added to the construction water in order to protect the well from contamination. Please refer to the tables in Section 9 to determine the proper amount of chlorine to use.

5.3.2 PLUMBNESS AND ALIGNMENT. Each drilled well shall be tested for plumbness and alignment and the bore of the hole shall be sufficiently plumb and straight to receive the casing without binding. The casing shall be sufficiently plumb and straight that it will not interfere with installation and operation of the pump.

5.3.3 YIELD. Each well shall be tested for yield and draw down by pump, bailer, or air.

5.4 CASING. The casing shall be installed where the purpose of casing is to seal off surface, near surface, or deeper contaminants or where the purpose is to retain the wall of the well in addition to repelling outside contaminants. In selection of casing pipe, consideration shall be given to the strain to which the pipe will be subjected during construction and the corrosiveness of the water with which it comes in contact. Used or reject pipe is not acceptable.

5.4.2 TEMPORARY (OUTER) CASING. Casing intended for construction purposes only shall be of weight and design as necessary to be watertight and permit installation without distortion or rupture to the specified depth.

5.4.3 GROUTING GUIDES. Protective casing that is to be grouted in the drill hole should have sufficient guides welded to the casing to permit the unobstructed flow and disposition of the thickness of grout specified.

5.4.4 SCREENS. Screen openings shall provide the maximum amount of open area consistent with the strength of screen and the grading of the water bearing formation or gravel pack. The opening shall permit maximum transmitting ability without clogging or jamming.

5.4.5 JOINTS. All casing pipe joints shall be watertight welded construction or threaded couplings.

5.4.6 UPPER TERMINAL. The Casing, well curb or riser pipe shall be terminated at a height above ground surface consistent with the proposed plans for a pump house and pump installation but not less than eight (8) inches above ground surface or twenty-four (24) inches above maximum high water level where flooding occurs.

5.4.7 STEEL CASING FOR DOMESTIC, INDIVIDUAL, AND STOCK WELLS. Casing for domestic, individual and stock wells of steel construction shall be as follows: Eleven (11) pound, minimum, black steel pipe may be used in consolidated formations. ASA Galvanized Standard Weight Schedule 40 pipe, one (1) inch I.D. to four (4) inches I.D. pipe size and weight are covered in Table 1. 4.090 inch I. D. galvanized pipe, 9-1/2 pound (schedule 30) may be used on a statewide basis with the following provision that any failure of this weight pipe within a five year period be replaced by the contractor at no cost to the landowner.

5.4.8 PVC CASING. Effective January 1, 1989, PVC plastic casing may be used provided the PVC pipe is manufactured as water well casing and is permanently marked as well casing. The casing shall be made to ASTM F480. The Contractor shall be responsible to assure that the PVC wall thickness shall be sufficient to withstand both the formation and hydrostatic pressures imposed on the casing during its installation and development. PVC casing shall be used only when construction practices will allow the bore hole to remain open during casing installation and the casing can be lowered freely without driving.

5.4.9 FIBERGLASS CASING. Fiberglass reinforced plastic well casing, tested in accordance with ASTM D1180 (American Society Testing Materials), may be used where judged desirable by the contractor and approved by the customer, in consolidated and unconsolidated formations. Each coupling shall form a watertight seal. Pipe having a minimum bursting pressure of 660 PSI may be used.

5.4.10 CASING OF INDUSTRIAL AND IRRIGATION WELLS.

5.4.10.1 GENERAL. All casing, including steel shall be strong enough to resist the forces imposed during installation and other forces that can be expected after installation. It shall be the contractor's responsibility to see that all casing used in industrial and irrigation wells will not collapse. Any material used in construction of industrial and irrigation wells that collapses or breaks within five years shall be renewed with a material strong enough to withstand the stress or pressure without charge to the customer.

5.4.10.2 PVC CASING. PVC 160 PSI NSF or stronger material classification may be used in construction of industrial and irrigation wells, where judged desirable by the contractor and approved by the customer in unconsolidated formations. All pipe shall be permanently marked under a method suitable to the National Sanitation Foundation. Plastic pipe must be made of new, not reclaimed material.

5.4.10.3 JOINTS. The joints of all casing shall be watertight and plumb and in alignment. All casing shall be installed so as to seal off water bearing formations that contain undesirable water (such as saline) and prevent water from the surface entering the fresh water aquifer so as not to contaminate them. Each joint of PVC pipe shall have a minimum of four (4) screws or rivets in the coupling.

5.4.11 CASING IN CONSOLIDATED FORMATIONS. Metal or plastic casing shall extend a minimum of one (1) foot into solid bedrock or slate in a cement or Bentonite seal at least one (1) inch thick from rock upward for five (5) feet. In wells where consolidated formations, such as bedrock or slate, occur as a definable unit, the casing shall be set into the consolidated formation and sealed below all crevices that would normally release water of inferior quality into the well. Plastic casing may be used to case through overburden in consolidated formations, providing the casing meets the requirements for the depth being cased.

5.4.11. 1 ROCK BELOW CREVICED FORMATION. The diameter of the drill hole through the creviced formation shall be a minimum of two (2) inches greater than the diameter of the casing. If an outer casing is left in place in the earth mantle, the annular opening around that casing shall be sealed as outlined in Section 5.4.11. All wells constructed in consolidated formations shall be cased a minimum of ten (10) feet from ground surface or one (1) foot minimum into the consolidated formation.¹ All casing left permanently installed in consolidated formations shall be grouted with the appropriate materials, as outlined in Section 5.5, from the bottom of the casing upward five (5) feet. Where a desirable water bearing formation underlies a crevice or undesirable water bearing formation, the overlaying formation should be completely grout sealed and watertight. Drilling construction should extend into the desired formation.

¹Ten feet from ground surface or one foot minimum in to the consolidated formation means that wells must be cased at least ten feet. Wells will never have less than 5 feet of cement or Bentonite grout in the annulus. Wells must also be cased at least one foot into consolidated formations. Minimum of one foot into consolidated rock means that many times even thought the formation is consolidated, ground water, at a particular depth would be undesirable and additional casing and grout to a depth greater than one foot into consolidated formation is required.

5.4.12 CASING IN UNCONSOLIDATED FORMATIONS. Unconsolidated formations such as sand and gravel may extend to or near the ground surface. Generally, however, they lie below the ground surface at varying depths and are covered by an over burden of earth. The kind, nature and depth of the over burden are factors in determining how a well shall be constructed. Wells constructed in unconsolidated formations shall have a permanent casing installed, in which the casing or screen shall extend the complete length of the drill hole. A minimum of the upper ten (10) feet shall be filled with grout after the casing is in place.

5.4.12. 1 GRAVEL WALL CONSTRUCTION. When an oversized drill hole is constructed to permit the placement of a gravel wall around the well screen or perforated casing, the annular opening between the casing and the drill hole shall be sealed in the top twenty (20) feet with concrete, cement, or Bentonite grout. If a permanent outer casing is installed, it shall extend to a depth of at least twenty (20) feet depending on the formations present, the annular opening between the drill hole and the outer casing shall be sealed as provided for in Section 5.4.12. The annular opening between inner and outer casings shall be filled with concrete, cement, or Bentonite grout in the upper twenty (20) feet.

5.5 GROUTING.

5.5.3 CONCRETE. This mixture should consist of cement, sand, aggregate (gravel), and water in the proportion of one bag of cement (94 pounds) and an equal amount of dry sand and aggregate and clean water. Concrete can be used in the top ten (10) feet of the annular space around the casing of the large diameter wells when the annular space is larger than two (2) inches from the outside of the casing wall to the face of the bore hole. Aggregate shall be no larger than 1/5 of the dimension between the outside casing and the face of the bore hole. All concrete shall be placed to prevent voids.

5.5.4 BENTONITE GROUT. Bentonite or sealing clay grout is a manufactured clay product that expands in contact with moisture to form a seal that prevents the movement of water and may be used in consolidated and unconsolidated formations. It is the responsibility of the contractor to make the viscosity of the Bentonite thick enough to seal out all contaminates.

5.5.5 GROUTING OF METAL-CASED WELLS. Metal casing shall be encased in a cement seal at least two (2) inches thick from ground level to a distance of at least ten (10) feet below established ground surface.

5.5.6. GROUTING OF CURBED WELLS. Curbed wells shall be concreted at lease six (6) inches thick poured monolithically from the upper terminal to a distance of at lease ten feet below established ground surface.

The well seal shall be secure so as to prohibit entrance to the well from unauthorized persons without tools or excessive physical exertion.

5.6.2 TIMING. The well seal or cap shall be installed immediately upon completion of the well and prior to departure of the driller and or contractor or his drilling equipment from the well site. An effort should be made by the driller or contractor to insure that the well seal or cap provided/installed is compatible to the type of pump and pipe to be installed.

5.6.3 SEALS OR CAPS WHEN PUMP INSTALLED. Well seals or caps shall be installed on all water wells after pump installation, and shall be securely capped. The seal MAY provide ventilation but be sufficiently tight and secure to prohibit foreign objects, contamination, insects and other pests from entering the well. The well seal shall be secure to prohibit entrance to the well from unauthorized persons without tools or excessive physical exertion. All wells in consolidated areas will be vented with insect proof vents. If the well is located inside a building it shall be vented to the outside.

5.6.4 PITLESS ADAPTERS. Pitless adapter shall be installed in a manner that excludes entrance of water or other materials into the well.

5.6.5 TEST HOLES. The contractor shall insure that the well/hole is capped to prevent injury or pollution. If the test well is abandoned then the well shall be plugged as outlined in Section 5.8.

5.7 DISINFECTION.

5.7.1 GENERAL. Every new well, or existing water supply system that has been disrupted for service or repair, should be disinfected before it is returned to use. Water in the well and storage tank should be treated with a strong chlorine solution to destroy disease organisms. All pipe lines and fixtures in the distribution system should be rinsed and flushed with chlorinated water. All wells, excluding irrigation, will be disinfected.

5.7.2 TIMING. If the constructor of the well is also responsible for preparing the well for the pump installation and making the pump installations, disinfection may be postponed until his work is completed. In the event the constructor does not have this responsibility, it is required before capping the well that an appropriate amount of chlorine solution be introduced into the well.

5.7.3 DISINFECTION AND PUMP INSTALLATION. At the time of new pump installation or reinstallation of an existing pump, the water system shall be chlorinated to a minimum concentration of 50 ppm for a minimum of 24 hours. Each well shall be disinfected by tablets and/or liquid.

5.7.4 WATER. Water, which has made contact with pipe or equipment used in chemigation, shall not be allowed to back siphon or be used to backwash the well.

5.7.5 EMERGENCIES. If an emergency situation exists the water system may be used, provided, the system is not for human consumption, and the system is disinfected as soon as the situation permits. Refer to the tables in Section 9 for guidance on administering chlorine.

5.8 PLUGGING OR ABANDONMENT OF WELLS.

5.8.1 DRY HOLES. If no water is encountered and the landowner does not wish to abandon the well in the event that he might plan further development of the well at a later date, the contractor shall complete the well according to the rules and regulations, including casing, sealing, and capping the well. A letter from the landowner, stating his intentions of future development of the well, shall be sent to the Commission along with the well completion report.

5.8.2 SEALING OUT SOURCES OF CONTAMINATION. If an unconsolidated formation is more than ten (10) feet below ground surface, it is the contractor's responsibility to seal out any and all contamination, such as surface water or seepage, by placing the grout to the necessary depth.

Note: Liquid sodium hypochlorite in a 12-percent solution is often sold for use in water and wastewater treatment plants, and as a commercial bleach or for use in swimming pools. Utilizing a solution of this nature would call for a liquid (chemical) measure equal to one-half the volumes presented in column 5.

*EPA recommends a minimum concentration of 100 mg/ l available chlorine. To obtain this concentration, double the amounts indicated.

Where a dry chemical is used, it should be mixed with water to form a chlorine solution before putting it into the well.

* To produce a 400 PPM chlorine dosage

Note: Pellets Weight = 1.14 gram each, 25 pellets/oz., 400 pellets/lb.

1 cup of pellets = 1/2 lb., or 8 oz., or 200 pellets

Autotrol Corporation's Well Sanitizer chlorinating pellets can be used for well, storage tank, or cistern sanitization. The amount of pellets used will depend on the amount of water in the system to be sanitized. To produce a 400 ppm chlorine concentration, to sanitize a water system, use one-half (1/2) pound chlorination pellets for each 100 gallons of water in the system (1/2 lb/100 gal = 8 oz/100 gal = 200 pellets/100 gal = 1 cup pellets/100 gal). Table 3 shows how many pellets to use per 100 feet of water in various diameter wells.

Drilled Wells

1. Remove the cap or seal from the casing and measure the depth of the water in the well, then refer to the Table to determine how many chlorine pellets should be used. In some instances removing the seal to measure the water can be a difficult task, and it is easier to estimate well and water depth from well log or other records.

2. Remove well cap and determine if there is an unobstructed path from the top of the well to the water level. If it is not possible to remove the well cap, remove vent or sanitization access plug.

3. Drop one pellet into the well and listen to hear if it hits the water. If the pellet hits the water, drop one-half (1/2) the number of pellets determined to be needed into the well. These will sink to the bottom and sanitize the lower part of the well.

4. Mix the remaining pellets in a few gallons of water in a CLEAN plastic container and pour the solution into the well.

5. In order to mix the chlorine thoroughly throughout the entire water system, it is necessary to recirculate the water in the well. This can be accomplished by connecting a hose to an outside silcock that is located after the pressure tank. Use hose to run water back down the well (this also rinses upper portion of well). After about 15 minutes of recirculation the water, a strong chlorine odor should be apparent. Turn off hose.

6. Bypass water softener and filters and open each water outlet in the water system until chlorine is present in water. This procedure assures that all the water in the system is chlorinated.

7. Allow the chlorinated water to stand in the system for at least six (6) hours, and preferably overnight. After this, open an outside faucet and flush system until water runs chlorine free. Repeat flush operation on each faucet in system.

Note:

A. Chlorine may break loose iron deposits, slime and organic material. This material will make the water run colored. The material broken loose may plug pump screens. DO NOT CONTINUE TO RUN PUMP IF WATER DOESN'T FLOW.

B. The high level of chlorine required to sanitize a water system is corrosive to most metals and chlorine solution must not be allowed to remain in water system more than 36 hours before being completely flushed from system.

8. After system has been completely flushed, perform a bacterial analysis on the water following all applicable procedures.

Large Diameter Bored Wells

Calculate the volume of water in well by determining the total cubic inches or cubic feet of water in the well. Each 231 cubic inches of water is equal to one gallon. Each cubic foot of water is 7.5 gallons of water. Use 1/2 pound of chlorine pellets for each 100 gallons of water in well. Dissolve pellets in clean, plastic pail and add to well. Pour two cups of pellets directly into well. Connect a garden hose to a faucet in water system and run water from hose back down well. When strong chlorine odor is present in hose water, wash down sides of well with chlorinated water. Proceed with steps Nos. 6, 7 and 8 of instructions for Drilled Wells.

Springs and Cisterns

Mix about 1/2 cup of pellets in 5 gallons of water use this to scrub the walls of the spring box or holding tank. With a constant flow of fresh water from the spring there is probably no way of detaining the chlorine solution in the reservoir for more than a few minutes. However, the chlorinated water should flow through the pipeline to disinfect the distribution system. Cisterns can be disinfected in the same way but a source of clean water will be needed to flush the dirty waste out of the system.

Note: This product is intended to sanitize a water supply system that has been temporarily contaminated, and is not intended to solve a recurring contamination problem.

NOTE: These regulations are the minimum requirements for water wells constructed in Arkansas.
