Section 4. Reporting
4.1
Reports. Within ninety (90)
days after a water well has been constructed or repaired, the constructor shall
submit a report of construction to the Arkansas Water Well Construction
Commission on such forms as are prescribed and furnished by the Commission. The
date of construction and time of completion shall be the date and time the rig
is removed or pulled off the bore hole or well. Reports must be legible, must
supply all requested information applicable to the type of work done, and must
contain the longitude and latitude of the well location.
4.1.1
Test holes. When a water
well contractor constructs a test hole for a well that may be developed into a
water well, the contractor shall file a construction report within thirty (30)
days after the date of construction regardless of the stage of completion of
the water well.
4.2
Domestic wells. The contractor is required to maintain adequate
records at his place of business of pumps installed in water wells used for
domestic purposes. Generally all warranty information should be maintained as
well as depth of settings, size of wire, size of pipe, etc.
4.3
Copy to be provided to
customer. A copy of the construction report shall be provided to the
customer upon demand.
Section 5. Construction
Note: Construction requirements vary according to type of formation, type of well and intended use. Please review 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 consider 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 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 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 requested 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
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.
5.1.8
Relations to
buildings. With respect to buildings, the location of a well shall be as
follows:
5.1.8.1
Adjacent to
building. When a well must be located adjacent to a building, it shall
be located so 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.
5.1.8.2
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 11 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
so 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.
5.4.1
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.
5.4.2
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.
5.4.3
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.
5.4.4
Joints.
All casing pipe joints shall be watertight welded construction or threaded
couplings.
5.4.5
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.
5.4.6
Steel casing
for domestic, individual, and stock
wells. Casing for
domestic, individual and stock wells of steel construction shall be as follows:
Minimum eleven (11) pound 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 Rule 11. 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 (5) year period be replaced by the contractor at no cost to the
landowner.
5.4.7
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.
5.4.8
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.
5.4.9
Casing of industrial
and irrigation wells.
5.4.9.1
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 (5) five years
shall be renewed with a material strong enough to withstand the stress or
pressure without charge to the customer.
5.4.9.2
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 pipes shall be
permanently marked under a method suitable to the National Sanitation
Foundation. Plastic pipe must be made of new, not reclaimed material.
5.4.9.3
Joints. The joints of
all casing shall be watertight and plumb and in alignment. All casing shall be
installed 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.
5.4.10
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.
5.4.10.1
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 Rule 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 Rule 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 into 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.
5.4.11
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.
5.4.11.1
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 Rule 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.
5.5.1
Sand and cement
grout. This mixture should consist of cement, sand and water, in the
proportion of one bag of cement (94 pounds) and an equal volume of dry sand to
not more than six (6) gallons of clean water.
5.5.2
Neat cement grout. This
mixture should consist of one bag of cement (94 pounds) to not more than six
(6) gallons of clean water. Additives up to 6% by weight to increase fluidity
may be used.
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 least six (6) inches thick poured
monolithically from the upper terminal to a distance of at least ten feet below
established ground surface.
5.6
Well seals or
caps.
5.6.1
General. Well seals or caps installed on wells shall be securely
capped. The seal may provide ventilation but shall be sufficiently tight and
secure to prohibit foreign objects, insects and other creatures 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.
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 ensure 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
adapters 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 Rule
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
contacted 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 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 11 for guidance on administering
chlorine.
5.8
Plugging or abandonment of wells.
5.8.1
General. To restore
geologic and hydrogeologic conditions existing prior to a well's construction,
any person who abandons an abandoned well, as defined in Rule 10.28, must use
methods and materials that will protect the ground water from surface
contamination and prohibit cross-contamination (co-mingling) of aquifers. Clay,
cement, or bentonite will be allowed to plug wells with certain restrictions
applied when using bentonite.
5.8.2
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, including casing, sealing, and capping the well.
5.8.3
File well abandonment
form. All wells plugged in the State should be reported by the water
well contractor to the AWWCC on a well abandonment form to be approved by the
AWWCC within ninety (90) days of abandonment.
5.8.4.1
Consolidated
formations. When information has been obtained about a well completed in
a single consolidated aquifer from a water well construction report,
geophysical data, or usage of a down-hole camera, the well shall be plugged
with cement, clay, or bentonite to a depth of fifty (50) feet below the bottom
of the surface casing, with a minimum depth of one hundred (100) feet of depth
below land surface. The remaining depth of the well may be filled with clean
sand or pea gravel. Wells completed in more than one major aquifer must have a
minimum fifty (50) foot clay, cement, or bentonite seal emplaced in the
borehole within each confining unit between the aquifers, and between any
aquifer and the surface overburden.
5.8.4.2
No information. If no
information on well construction is available, the well must be filled from
bottom to within two (2) feet of land surface with clay, cement, or bentonite
in a manner that will protect the ground-water flow system.
5.8.5
Unconsolidated
formations. All wells in unconsolidated formations will be filled with
sand or natural material to twelve (12) feet of ground surface, from twelve
(12) feet to two (2) feet with bentonite or cement.
5.8.6
Usage of packers. Packers
should be emplaced in wells overlying flowing artesian aquifers, or aquifers
with more than seventy-five (75) feet hydrostatic head to curtail flow prior to
plugging and prevent intercommunication of aquifers.
5.8.7
Usage of bentonite.
5.8.7.1
Chips. Bentonite chips
may only be used to plug a well if the well's diameter is four (4) inches or
more, the well's depth is less than six hundred (600) feet below land surface,
and the well contains less than five hundred (500) feet of standing
water.
5.8.7.2
Slurries. Bentonite slurries are not allowed for well abandonment
in the unsaturated zone (above water level).
5.8.7.3
Prohibited use of bentonite
under certain
conditions. Bentonite should only be used in
accordance with package label recommendations.
5.8.8
Caves. A driller should
contact AWWCC staff for specific abandonment procedures if he encounters caves
while drilling.
5.9
Fracturing.
5.9.1
General. Fracturing
includes the use of explosives, acid, or pumping fluids (hydrofracturing) into
a water well. A Driller registered in category 4 shall supervise
hydrofracturing. A driller registered in category 1-3 may use explosives or
acid without being registered in category 4. Wells which do not meet the
requirements of these construction rules shall not be fractured.
5.9.2
Water. Water used in
fracturing must be free of contamination and chlorinated to fifty (50)
milligrams per liter chlorine prior to injection.
5.9.3
Relation to sources of
contamination. Water wells located closer than one hundred (100) ft. to
any potential source of contamination shall not be fractured.
5.9.4
Process. The following
action must take place when hydrofracturing a water well:
1. Analysis of the well site and well to
determine the location of other wells and potential sources of contamination in
the immediate vicinity. Determine if the well needs repair and if so bring up
to standards. Determine the effect on geological formations and ground
water.
2. Conduct a test and
estimate well yield.
3. Advise
owner of hazards and potential liability of fracturing.
4. Disinfect well to be fractured to 50
milligrams per liter chlorine.
5.
Fracture well.
6. Reinstall pump
equipment.
7. Disinfect well and
pump equipment.
8. Pump well to
recover no less than the amount of water injected.
9. Conduct test and estimate well
yield.
10. Complete a construction
report. On the report, in the space provided for description of formation,
indicate the depth and PSI (or amount of explosive) of each zone fractured.
* The above steps are not meant to be all inclusive. The contractor remains responsible and liable for damages to the well or wells in the immediate vicinity resulting from hydrofracturing, even though the Contractor may have complied with these rules.
5.9.5
Consolidated formations.
Fracturing PSI shall not be excessive.
Section 6. Special well construction techniques
6.1
Artesian
wells. In known artesian territories, initial drilling
operations shall extend into but not through the formation confining the water.
The casing shall be installed and the annular opening between the drill hole
and casing sealed with cement or Bentonite grout and allowed to set. The hole
shall then be extended into artesian formation. Flow control from the well
shall be provided by valved pipe connections, watertight pump connections, or
receiving reservoirs set at an altitude corresponding to the artesian
head.
6.2
Driven,

bored or driven, unless the type or purpose of the well applies to all methods
of well construction (test holes, heat pump wells etc.).
6.2.1
Driven wells. On all
driven wells there shall be an outer casing grouted from ground surface to a
minimum ten (10) feet depth. Plastic or steel casing that will accommodate the
outside diameter of the pipe being driven shall be placed in a hole that has a
minimum diameter of four (4) inches larger than the surface casing. This should
give a minimum of two (2) inches thickness of grout.
6.2.2
Dug or bored wells. Every
dug or bored well shall have a continuous watertight lining of steel casing or
concrete pipe extending from above ground surface to a depth of at least ten
(10) feet below the ground surface. When more than one formation bearing
suitable water exists, the lower formation should be used. The lining in the
producing zone shall readily admit water and shall be structurally sound to
withstand external pressures.
6.2.3
Annular openings. The open space between the excavation and the
installed lining shall be sealed with grout. If the first ten (10) feet of the
casing is jointed, such as concrete, and would allow surface water to seep into
cracks of casing, the grout will continue from the ten (10) foot seal to ground
level.
6.2.4
Upper
terminal. The watertight lining shall extend at least eight (8) inches
above finished ground surface. A cover slab at least two and one half (2 1/2)
inches thick, adequately reinforced and having a diameter sufficient to overlap
the lining by two (2) inches shall be provided. The top of the slab shall be
sloped to drain to all sides and a watertight joint made where the slab rests
on the well lining using cement mortar or a mastic compound. A manhole, if
installed, shall consist of a metal curb cast in the slab and extending four
(4) inches above the slab. The manhole shall have a watertight covering having
sides to overhang the curb at least two (2) inches. Adequately sized pipe
(plastic pipe may be used) shall be cast in place in the slab, extending at
least eight (8) inches above the slab, to accommodate the type of pump or pump
piping proposed for the well. If the well contractor does not install the pump,
a cap (seal) will be placed on top of the pipe. The owner or licensed driller
may cut off the cap and must leave a minimum of two (2) inches above the
slab.
6.3
Industrial and irrigation wells. This
section applies to wells constructed for purposes other than human consumption.
6.3.1
Outer casing seal for gravel
well industrial and irrigation wells. Industrial wells
shall be sealed with a concrete slab or grouted or both. Irrigation wells shall
be sealed with a bentonite seal. It is optional to use a slab for an irrigation
well.
6.3.1.1
Slabs. Slabs must
be of reinforced concrete and at least four (4) inches thick and have a
diameter sufficient to overlap the drill hole by two (2) feet. The top of the
slab shall be sloped to drain to all sides.

composed of sodium montmorillonite clay, also known as Bentonite, cement, or a
sodium montmorillonite (Bentonite)-cement mixture and shall fill the annular
opening between the casing and the drill hole in the upper ten (10)
feet.
6.3.1.3
Timing.
If noted on the Report of Water Well Construction, a slab may be placed on
non-grouted wells within one year of the date of construction to allow for
settling.
6.3.1.4
Gravel
refill pipes. Gravel refill pipes may be installed if they terminate
above the concrete slab surface and are provided with watertight
caps.
6.3.2
Public
notice. Each new industrial or irrigation well and each existing
industrial or irrigation well when brought under the rules of the Act shall
have a weatherproof sign attached in a conspicuous location stating that "THIS
WATER IS NOT FOR DRINKING PURPOSES" or a suitable decal of weatherproof
material.
6.3.3
Casing,
screen, and all material for industrial and irrigation wells of steel
construction over four inches in diameter.
The minimum wall thickness shall be seven gauge or .1875. All material used shall not allow sand or sediment to enter a well. Where there is an acid condition screen material may be stainless steel, plastic, bronze, or other material suitable for the water and ground formations in which the well has been completed.
6.3.4
Gravel refill pipes. Gravel refill pipes may be installed if they
terminate above ground surface and are provided with water tight
caps.
6.3.5
Artificial
pack. Wells designed for placement of an artificial pack shall be
provided with an adequate screen having openings based upon size of the gravel.
The well shall be developed to insure free entry of water without
sediment.
6.4
Geothermal (heat pump) wells. Heat pump
wells are designed for two major types of Heat pump Systems.
6.4.1
Closed loop or earth
coil. Fluid is circulated in a continuous unbroken pipe beneath the
surface of the earth or under ponds, swimming pools, lakes or in a medium where
the system can obtain a sufficient cooling or heat exchange. Normally no fluid
is gained or lost. Depths of installation vary and are dependent upon the type
and size of closed loop system, the land area available, soils/formation,
climate, and seasonal variation in ground temperature, etc. There are three
types of closed loop heat pump well systems:

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 number 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.
