(1) 
Casing.
(a) 
All wells serving as a water supply shall be equipped with a watertight and durable wrought-iron, steel or other type of approved casing equivalent to Schedule 40 280 wall thickness. The section of casing shall be joined together by threaded couplings or joints, by welding, or by any other watertight approved joint or coupling. The casing shall be carried to a minimum depth of 40 feet and (then) extended an additional five feet into firm bedrock or other impervious strata and grouted in place. Well casing material other than wrought iron or steel must be resistant to the corrosiveness of the water and to the stresses to which it will be subjected during installation and the grouting operation. Casing and grouting material must be compatible. The criteria established in AWWA Standard A100-15 must be followed. Casings shall terminate a minimum of 18 inches above the surrounding, finished ground surface grade. All casings for water supply or geothermal return wells shall be fitted with an insect-resistant well cap.
[Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I)]
(b) 
Ferrous casings shall be new pipe meeting ASTM or API specifications for water well construction, have additional thickness and weight if minimum thickness is not considered sufficient to assure reasonable life expectancy of the well, be capable of withstanding forces to which it is subjected and have full-circumference welds or threaded pipe joints.
(c) 
Watertight well casing must be placed at a sufficient depth to prevent the entrance of pollution from surface runoff and polluted aquifers.
(2) 
Grout materials and placement.
(a) 
All grout information (type of cement or bentonite and number of bags of cement or bentonite used for grouting) must be submitted in writing on Form WTWSD-01 to the Department by the well driller within 30 days of completion of the well drilling process.
(b) 
In all well installations, an annular space shall be provided between the well casing and the earth formation. The annular space shall be completely filled with approved grout materials, in one continuous operation, under pressure from the bottom to the natural land surface, within 24 hours after completion of the drilling. In the event that grouting is done following the completion of all drilling operations, care must be taken to prevent the entrance of drillers mud into the annulus during the completion of the bore hole by the use of a rubber packer or other acceptable method. The annular space shall be completely cleared of all obstructions prior to the placement of the grout material. Exterior grouting methods must be used in this instance. The casing shall be sealed effectively against entrance of water from water bearing zones which are subject to pollution, through which the casing may pass, by grouting a minimum of 10 feet above and 10 feet below the polluted or undesirable water-bearing zone. During the installation of the pitless adapter, grout material may be removed from the exterior of the casing in order to provide a watertight seal between the casing and the pitless adapter.
(c) 
After the grout has been placed in the annular space, drilling of the bore hole may proceed for a maximum of four hours; and if not completed within that time period, a curing time of 36 hours must be provided before drilling may resume. A curing time of 12 hours for Type III portland cement must be provided immediately following the placement of the grout. Drilling is not permitted during the curing period. If casings of smaller diameter are used in the lower portions of the well, effective watertight seals shall be provided between the casings where they telescope for a minimum distance of four feet.
(d) 
The annular space of all well installations must be filled with one of the following listed grout materials:
[1] 
Neat cement grout shall consist of a mixture of API Class G (or Class B similar to ASTM C150 Type II) and water in the ratio of 0.67 cubic foot (0.019 m3) of water per ninety-four-pound (42.7 kilograms) sack weighing approximately 228 pounds per cubic foot. A maximum of 6% by weight of bentonite and 2% by weight of calcium chloride may be added.
[2] 
Pozmix-cement grout shall consist of a mixture of 50% by volume of Pozzolan A (74 lbs./cu. ft.3) (1185 kg/m3) and 50% by volume of API Spec. 10, Class G cement with 0.77 cubic feet (0.02 m3) of water per 84 pounds (38.2 kilograms) of mixture. To this mixture of 2% by weight of calcium chloride, at the discretion of the contractor.
[3] 
Concrete grout shall contain 5.3 sacks of Portland cement (ASTM C150 Type II) per cubic yard of concrete and a maximum of seven gallons (0.026 m3) of water per ninety-four-pound (42.7 kilograms) sack of cement. The maximum slump shall be four inches. The aggregate shall consist of 47% sand and 53% coarse aggregate, conforming to ASTM Designation c-33. The maximum size aggregate should be 0.75 inches. Concrete grout shall not be placed in an annulus of less than three inches.
[4] 
Sand cement grout shall consist of a mixture of Portland cement (ASTM C150 Type II), sand and water in the proportion of not more than two parts by weight of sand to one part of cement with not more than six gallons (0.022 m3) of water per ninety-four-pound (42.7 kilograms) sack of cement.
[5] 
Bentonite grout shall be a pure bentonite with at least 20% solids by weight when mixed with water. Hydration of the bentonite must be delayed until bentonite mix has been placed down the well. This can be done by using additives with the dry bentonite or in water; mixing calcium bentonite with sodium bentonite or by using granular bentonite which has less surface area.
[6] 
In all well installations, if rapid loss of grout material occurs during placement, coarse fill material (e.g., sand, gravel, crushed stone, dry cement) may be used in the zone or zones in which the rapid loss is occurring. The remainder of the annular space shall be grouted as provided below. In no case shall pouring, dumping or shoveling of grout material into the annular space be deemed an approved method of grout placement.
(3) 
Grout placement.
(a) 
Grout pipe outside casing.
[1] 
The minimum annular space of 1 1/2 inches around the entire outside of the casing shall be provided by drilling a bore hole three inches larger than the outside diameter of the casing to be inserted. All grout shall be placed by pumping through the grout pipe. The entire interval to be grouted shall be open and without obstructions. Washing or jetting with water is recommended for cleaning the bore hole and may serve to remove obstructions caused by casing which otherwise would prevent a proper grout. It is recommended that the grout pipe extend from the surface to the bottom of the interval to be grouted. The grout pipe may remain extended to the bottom of the interval during and after grouting, or it may be raised slowly as a grout is placed, provided that the discharge end of the grout pipe remains submerged in the emplaced grout at all times until grouting is completed. In the event of interruption in the grouting operations, the bottom of the grout pipe shall be raised above the grout level and should not be resubmerged until the air and water have been displaced from the grout pipe.
[2] 
Grouting depths greater than 30 feet. The minimum length of grout pipe shall be inserted into the annular space is 30 feet.
[3] 
Grouting depths of 30 feet and less. Grout may be placed by a tremie pipe inserted only a short distance (approximately five feet into the annular space, provided that the entire interval to be grouted is clearly visible from the surface and is dry. An annular space larger than the minimum 1 1/2 inches may be required to assure visibility from the surface.
(b) 
Grout pipe inside casing. The bottom of the casing is fitted with a packer arrangement, also referred to as a "cementing shoe" or "float shoe," and the casing is placed in the bore hole a short distance off the bottom. The float shoe allows grout to be pumped through the grout pipe and upward into the annular space while preventing grout leakage into the casing during grouting and after removal of grout pipe. Grouting is continued until cement appears at the surface, at which time the grout pipe is disconnected from the float shoe. The float shoe is drilled out after the grout sets and hardens sufficiently.
(c) 
Interior method two plug. The first plug separates the grout from the fluid in the casing, and the other separates the grout from the water pumped in above it. First, the casing is placed a short distance off the bottom. After pumping water through the casing to circulate fluid in the annular space and clear any obstructions from the hole, the first plug is inserted, and the casing is capped. A measured volume of grout is pumped in which is sufficient to fill the annular space. The casing then is opened, and the second plug inserted. A measured volume of water is pumped in above the second plug until it is pushed to the bottom of the casing and most of the grout is expelled up and into the annual space. The water in the casing is held under pressure to prevent the backflow of grout until it has set and hardened.
(d) 
Interior method upper plug. The casing is placed a short distance off the bottom, and the water is pumped into the casing to circulate fluid through the annular space to clear any obstructions from the hole. A measured quantity of grout slightly greater than that needed to fill the annular space is pumping into the capped casing. Because this grout is in direct contact with the drilling fluid, there will be a narrow zone of weak grout between the drilling fluid and good grout; however, this zone should remain inside the casing and not be forced into the annular space. The casing is opened, and a drillable plug is inserted. A measured volume of water is pumped in above the plug until it is pushed to the bottom of the casing and most of the grout is expelled up and into the annular space. The water in the casing is held under pressure until the grout sets and hardens.
(e) 
Interior method capped casing. The casing is placed a short distance off the bottom, and water is pumped into the casing to circulate fluid in the annular space and clear any obstructions from the hole. The grout pipe passes through an airtight cap at the top of the casing and is positioned three to four feet above the bottom of the casing. The grout pipe is assembled so that it can be pulled through the cap a distance of about 20 feet after the injection of grout is completed. A bleeder valve is provided to release air from inside the casing as it is filled with water. The first step is to fill the casing and annular space with water. With the upper end of the casing closed, grouting is started by forcing the cement through the grout pipe upward into the annular space. Grouting is continued until the cement overflows around the casing at ground surface. Just enough water is pumped to clear the cement from the grout pipe, and the grout pipe is lifted free of the grout. Both the casing and grout pipe shall be kept tightly closed under pressure until the cement sets and hardens.
(f) 
Grout displacement method. The hole is filled with the estimated volume of grout required to fill the annular space, and the casing is lowered into the hole. The bottom of the casing is closed in a tight, drillable plug. Guides often are used to keep the casing centered in the hole. As the casing is lowered, the grout is forced upward around it to fill the annular space. If the pipe does not sink to the bottom under its own weight, it is filled with water.
(g) 
Unconsolidated formations. When drilling through an unconsolidated formation, a steel drive shoe shall be required. Grouting shall be done in accordance with the following:
[1] 
If caving conditions are experienced on wells deeper than 30 feet, the annular space shall be grouted from the point where caving occurred or from a depth of 30 feet, whichever is greater, to land surface.
[2] 
If the annular space cannot be grouted in accordance with these regulations, the well shall be abandoned and sealed in accordance with § 353-9 of this article.
(h) 
Other grouting methods and materials may be used subject to prior written approval of the Department.
(4) 
Packers. Packers, when used, shall be of materials that will not impart taste, odor, toxic substances or bacterial contamination to the well water.
(5) 
Well screens. Well screens, when used, shall:
(a) 
Provide the maximum amount of open area while still maintaining structural strength.
(b) 
Have the size of openings in the screen based on a sieve analysis of the material contained in the surrounding geological formation or gravel pack.
(c) 
Be constructed of materials resistant to damage by chemical action of groundwater or cleaning operations.
(d) 
Have sufficient diameter to provide adequate specific capacity and low-aperture velocity. Usually, the entrance velocity should not exceed 0.1 foot per second.
(e) 
Be installed so that the pumping water level remains above the screen under all operating conditions.
(f) 
Be designed and installed to permit removal or replacement without adversely affecting watertight construction of the well.
(g) 
Be provided with a bottom place or wash-down bottom fitting of the same material as a screen.
(6) 
Gravel packs. Gravel packs, when used:
(a) 
Shall be well rounded particles, 95% siliceous material, that are smooth and uniform, free of foreign material, properly sized, washed and disinfected immediately prior to or during replacement.
(b) 
Shall be placed in one uniform continuous operation.
(c) 
Gravel refill pipes, when used, shall be Schedule 40 steel pipe incorporated within the pump foundation and terminated with screwed or welded caps at least 12 inches above the pump house floor or concrete apron.
(d) 
Gravel refill pipes located in the grouted annular opening shall be surrounded by a minimum of 1.5 inches of grout.
(e) 
Protection from leakage of grout into the gravel pack or screen shall be provided.
(7) 
Pit installations. Pit installations are used where the casing terminates below the ground surface. Where well pits are used, such pits shall be maintained free of water at all times. The floor of the pit shall be a watertight reinforced concrete platform at least four inches thick poured around the casing and shall be provided with a watertight seal. The floor of the pit shall extend at least two feet from the center of the casing in all directions. In all cases, the pit shall be sized to allow adequate working space. The casing shall extend above the floor for at least 12 inches. An insect-resistant well cap shall be installed. The surface of the floor shall be pitched toward a drain which has a minimum diameter of four inches and discharged by gravity to the surface of the ground in an area not subject to flooding or to a basement which is effectively protected against flooding. Drain openings shall be effectively screened to prevent the entrance of insects and rodents. The drain shall not be connected to any sewer or other drain. The pit shall have watertight reinforced concrete walls four inches thick or equivalent which provide for an effective watertight seal against the floor. The top of the pit shall be a watertight reinforced monolithic concrete slab at least four inches thick, which shall be sealed with the wall so as to effectively prevent the entrance of water. The top of the pit shall not be more than six inches below the ground surface. A durable watertight manhole shall be installed in the top of the pit centered over the casing and effectively sealed with the top to prevent the entrance of water. This manhole shall be at least 24 inches in diameter. It shall extend at least three inches above the surrounding ground surface and be covered by an impervious durable cover of concrete, steel or equivalent material which overlaps the manhole vertically by at least two inches. The manhole cover shall be effectively secured to the manhole by bolting, locking or equivalent means and shall be kept so secured. Pit installations shall not be used in areas subject to flooding by groundwater or surface water or where the groundwater level rises to within one foot of the bottom of the proposed pit. Where pipes enter the pit, the annular space between the pipes and the wall shall be effectively sealed by a watertight permanent seal.
(8) 
Pitless installations. Pitless installations are those installations where the casing terminates above the ground surface.
(a) 
Where pitless installations are used, they shall be of a design which provides an effective seal against the entrance of groundwater or surface water into the well, access casing and into the piping leading to the pump. All buried suction lines shall be effectively encased or otherwise protected to prevent external damage or contamination. Pitless installations must be so designed as to be structurally sound and to provide for ready removal of drop piping without excavation. The access casing shall be effectively protected against corrosion and shall extend at least 18 inches above the natural ground surface and to a point below the frost line. The ground level at this point shall be elevated above the adjacent ground level and graded to drain away in all directions. The top of the access shall be effectively sealed against the entrance of waters, insects and rodents. An insect resistant cap shall be installed. The pitless adapter shall not be submerged in water or used in areas used by automobiles and other vehicles.
(b) 
Where surface installations (i.e., hand pumps, pump rooms, etc.) are used, a watertight reinforced-concrete platform at least four inches thick and extending for at least two feet in all directions from the center of the casing shall be poured around the casing to provide an effective watertight seal with the casing, or it shall be made watertight with an effective permanent seal. The surface of the platform shall slope to the edges. The casing shall extend through the slab for a least 12 inches and shall be effectively sealed against the entrance of contamination. An insect-resistant well cap shall be installed where appropriate. All pumping equipment shall be protected against freezing. If a pump room is proposed, it shall be so sized to allow adequate working space.
(9) 
Venting. Where venting is required, an overlapping cover or pipe with the opening facing downward shall be required.

As approved
(b) 
Any proposed deviation from the isolation distances prescribed in Subsection B(1)(a) above must be approved in writing by the Director, with reasons stated for such deviation.
(2) 
Construction.
(a) 
Closed-loop geothermal bore holes shall be located, drilled and finished in a manner that will protect the bore hole structure from damage from surface activities or other natural occurrences so that the quality of the groundwater cannot be affected.
(b) 
The well contractor shall be responsible for ensuring that the bore hole is drilled in the permitted location. Deviation from the permitted location must receive prior written approval from this Department. The well contractor shall be responsible for drilling the bore hole and the final backfilling after the pipe loop has been installed.
(c) 
Casings are not required. Casings may be necessary to hold the bore hole open during the drilling process. Casing may be left in the bore hole at the discretion of the well contractor. When a casing is used, grouting the annular space is required.
(d) 
The pipe loop is to be installed by a contractor who is certified in the proper method of heat fusion specified by the pipe manufacturer. The well contractor shall be responsible for insuring that the pipe loop is installed in accordance with the specifications of the ground source heat pump system manufacturer, the pipe manufacturer and that the bore hole is properly backfilled.
(e) 
Backfilling shall be according to the specification of the ground-source heat pump equipment manufacturer. When sand is the specified backfill material, the bore hole shall be constructed in the same manner as a water supply well. A casing is required to be used, and the annular space is required to be grouted.
(f) 
If the closed-loop bore hole penetrates bedrock, it must be grouted from a depth of 15 feet into the bedrock to the top of the bore hole.
(g) 
The recommended backfilling material for these bore holes shall be bentonite. The bentonite shall conform to the grouting standard specified in § 353-6B(2)(d)[5].
(3) 
Permitting. Closed-loop geothermal bore holes shall be permitted in accordance with § 353-12. Each bore hole must be permitted using a single application. A separate fee will be charged for each bore hole.
A fee schedule will be established for these rules and regulations and adopted annually by the Board of Supervisors.
