Well Construction Permits are not transferable.

A plumbing permit shall be obtained prior to any repair, modification or replacement of any existing well used for consumption purposes.


The applicant shall submit to the Board, for review and approval, a Pumping Test Report.  The Pumping Test Report shall include the name and address of the well owner, well location, referenced to at least two permanent structures or landmarks, date the pumping test was performed, depth at which the pump was set for the test, location of the discharge line, static water level immediately before pumping commenced, maximum draw down during the test, duration of the test, including both the pumping time and the recovery time during which measurements were taken, recovery water levels and respective times after cessation of pumping and the reference point used for all measurements; In order to demonstrate the capacity of the well to provide the required volume of water, a pumping test shall be conducted in the following manner:


(a)        Single Family and Duplex (up to five bedrooms in total) shall require a minimum quantity of five gallons per minute for a continuous four-hour period.


(b)      Multi-Family uses (for more than five bedrooms, or as defined by 310 CMR 22.00 up to sixteen connections or twenty five people) shall require

                                                                                                   i.      A peak load storage and well production of five gallons per minute for a continuous four hour period per unit or connection and

                                                                                                  ii.       A total storage and production to meet the following formula

a.        (# of bedrooms + 1)x(110 gallons/bedroom)x(safety factor of 2) equals the number of gallons needed daily plus the storage capacity of the well as determined by using the static water level and the depth and radius of the drill hole or casing and

b.         Provide a minimum production rate of five gallons per minute for a four hour period.

The pumping test may be performed at whatever rate is desired.  Following the pumping test, the water level in the well must be shown to recover to within eighty-five percent of the pre-pumped static water level within a twenty-four hour period.


The issuance of a Water Supply Certificate by the Board of Health shall certify that the private well may be used as a drinking water supply.  A Water Supply Certificate must be issued for the use of a private well prior to the Issuance of an Occupancy Permit. For an existing structure which is to be served by the well.

The following shall be submitted to the Board of Health to obtain a Water Supply Certificate:

1         a copy of the certified laboratory’s test results

2         the name of the individual who performed the sampling

3         where in the system the water sample was obtained

The Board reserves the right to require retesting of the above parameters, or testing for additional parameters when, in the opinion of the Board, it is necessary due to local conditions or for the protection of the public health, safety and welfare.  All costs and laboratory arrangements for the water testing are the responsibility of the applicant.


Pursuant to 313 CMR 3.00, no person in the business of digging or drilling shall construct a well unless registered with the Department of Environmental Management/Division of Water Resources.

Any work involving the connection of a private well to the distribution system of the residence must conform to the local and state plumbing and electrical codes.

A physical connection is not permitted between a water supply, which satisfies the requirements of these regulations, and another water supply that does not meet the requirements of these regulations without prior approval of the Board.

The driller shall operate all equipment according to generally accepted standards and shall take appropriate precautions to prevent damage, Injury or other loss to personal and property at or about the drilling site.

Well construction design shall insure that surface water does not enter the well through the opening or by seepage through the ground surface.  Construction site waste and materials shall be disposed of in such a way as to avoid contamination of the well and the aquifer.  During any time that the well is unattended, the contractor shall secure the well in always as to prevent either tampering with the well or the introduction of foreign material into the well.

Well yield shall be measured and recorded at least every fifty feet during drilling.

All water used for drilling well development or to mix a drilling fluid shall be obtained from a source, which will not result in contamination of the well or the water bearing zones penetrated by the well.  Water shall be conveyed in clean sanitary containers or water lines and shall all be chlorinated to an initial concentration between 50 mg/1 and 100 mg/1.  Free chlorine residual of 10 mg/1 shall be maintained in any water used at the drill site.  Water from wetlands, swamps, ponds, and other similar surface features shall not be used.

All drilling equipment, including pumps and down hold tools, shall be cleaned and disinfected prior to drilling each new well or test hole.

All drilling fluids shall be nontoxic.  Drilling fluid additives shall be stored in clean containers and shall b free of material that may adversely affect the well, aquifer, or the quality of water to be pumped from the well, surfactants should be biodegradable.  The use of biodegradable organic polymers shall, when possible be avoided.  All wells, including those that have been hydro fractured, shall be developed in order to remove fine materials introduced into the pore spaces or fractures during construction.  One or more of the following methods shall be used for development:

a)     Over pumping

b)     Backwashing

c)     Surging

d)     Jetting

e)     Air-lift pumping



The completed well shall be sufficiently straight so that there will be no interference with installation, alignment, operation or future removals of the permanent well pump.

General Well Design and Construction

All private water supply wells shall be designed such that:

1         The materials used for the permanent construction are durable in the specific hydro geologic environment that occurs at the well site.

2         No unsealed openings will be left around the well that could conduct surface water or contaminated groundwater vertically to the intake portion of the well or transfer water from one formation to another


Permanent construction materials shall not impart toxic substances, taste, odors, or bacterial contamination to the water in the well.


Well Casing


Private water supply wells shall be constructed using either steel or thermo-plastic well casing.  The casing shall have an I/D of at least six inches and shall be of adequate strength and durability to withstand anticipated formation and hydrostatic pressures; the forces imposed on it during installation; and the corrosive effects of the local hydro geologic environment.

Steel casing shall be used with cable tool drilling or when the casing is installed in an open drill hole in which formation materials may suddenly collapse against the casing.

All casing used in the construction of private water supply wells shall be free of pits, breaks, gouges, deep scratches and other defects.  If previously used casing is installed, it shall be decontaminated and disinfected prior to installation.

Installation of water well casing shall be done in a manner that does not alter the shape, size or strength of the casing and does not damage any of the joints or couplings connecting sections of the casing.  A standard drive shoe shall be used when casing is installed.  The drive shoe shall be either welded or threaded to the lower end of the string of casing and shall have a beveled metal cutting edge forged, cast, or fabricated for this specific purpose.

Upon completion of the installation procedure, the entire length of the casing above the intake shall be watertight.

For wells completed above grade, the casing shall extend at least twelve inches above the proposed finish ground surface unless the well is located in a flood plain.  For well constructed in a flood plain, the casing shall extend at least two feet above the level of the highest recorded flood.  The top of the casing shall be reasonably smooth and level.

Steel Casing

Steel casing shall consist of schedule forty pipe that complies with materials standards approved by the American Water Work Association.

Segments of steel casing shall be coupled by using threaded casings, couplings, or by welding the joint.  Recessed or reamed and drilled couplings shall be used on threaded casing and no threads shall be left exposed once the joint is completed.  When welded casing joints are used, they shall conform to the most recent revision of AWWA c206, “Standard for Field Welding of Steel Water Pipe”.  The weld shall be at least as thick as the wall thickness of the well casing and shall be fully penetrating.  When completed, a welding casing joint shall have the tensile strength equal to or greater than that of the casing.









Thermoplastic casing

Thermoplastic casing used in the construction of private water supply wells shall be capable of withstanding pressures equal to or greater than 200 pounds per square inch and shall conform to the most recent revision of ASTM Standard F480, “Specifications for Thermoplastic Water Well Casing Pipe and Couplings Made in Standard Dimension Ratios (SDR)”.  In addition, the casing and cou0plings shall meet the requirements of the most recent revisions of National Sanitation Foundation Standard Number 14, entitled A Plastics Piping System Components and Related Materials”.  Materials complying with Standard Number 14 can be recognized by the marking “NSF – WC”.

Thermoplastic casing shall be stored in such a manner as to prevent decontamination, sagging or bending.  Storage of thermoplastic casing and coupling in direct sunlight shall be avoided.

Thermoplastic casing shall be installed only in an oversized drill hole and shall not be driven, pushed, or forced into a formation. Thermoplastic casing shall be joined by mechanical means only.  When pulling back thermoplastic well casing to expose a well screen the force applied shall not exceed the casing weight.

Concrete Casing

Dug wills are not recommended and shall be permitted only as a lost resort, upon receipt of a special request and an explanation as to why a drilled well cannot be installed.  Upon approval, the following shall be observed:

                        Concrete water well casing consists of either precast concrete pipe or concrete, which has been poured in place.  This type of casing shall be used only for the construction of dug well.

Precast concrete pipe shall be at least three inches thick, meet or exceed ASTM C67 Class III specifications and be free of blemishes.  Joints between pipe segments shall be sealed with a continuous, solid ring rubber gasket having a circular cross section with a sufficient volume to substantially fill the recess provided when the pipe joint is assembled.  (A properly sized gasket will form a pressure tight seal when it is compressed between pipe segments).

Well Screen

A well screen is necessary for all drilled wells that are completed in unconsolidated formations.  Wells completed in bedrock do not require a screen unless the bedrock formation is brittle in nature or has a potential for collapse.  The well screen aperture openings, screen length and diameter shall be selected so as not to limit the aquifers’ water yielding characteristics while preventing access of soil particles that would detract from well efficiency and yield

                                                Grouting and Sealing

When required, private wells drilled in bedrock shall be grouted from the top of the weathered rock interface to fifteen feet into competent bedrock.  Either neat cement or sand cement grout shall be used and it shall be emplaced using standard grouting techniques as described in the DEP Private Well Guidelines.

When required, wells completed with the casing extending above grade shall have a surface seal designed to eliminate the possibility of surface water flowing down the annular space between the well casing and the surrounding backfilled materials. The surface seal shall be:

a.        A cement cap extending at least two feet in all directions from the well casing.  The cement cap shall be at least four inches in thickness and shall have a finish slope leading away from the well casing.  The cement cap shall finish at the proposed finish grade.

b.        A surface seal shall be installed to extend from the cement cap to a depth of five feet below the proposed finish grade.  The surface seal shall be installed to a thickness of one and one half inches around the outside of the well casing for the full five feet in length.

Pumps and Pumping Equipment

All pumps shall be installed at or below the frost line with a pitless adapter or some other heated and protected sanitary location.  Above ground pumps shall be installed in sheltered, dry, accessible locations and shall be protected from freezing.

Shallow well pumps shall be installed as near the well or water source as possible to minimize suction lift.

Deep well pumps shall be installed directly over the well.  Submersible and helical rotor pumps must be installed in the well.  A deep well jet pump may be offset from the well.

                        Wellhead Completion

Well casing shall not be cut off below the land surface unless a pitless adapter or pitless unit is installed; or an abandoned well is being permanently plugged.  Well casing terminating above grade shall extend at least twelve inches above the proposed finish grade at the wellhead except when the wellhead is located in the flood plain.  When a well is located in a flood plain, the well casing shall extend at least 2 feet above the level of the highest recorded flood.  The top of the well casing shall be reasonably smooth and level.

Any well, except a dug well, that does not terminate at the base of the pump shall be equipped with a sanitary seal or weather tight cap designed to prevent surface water and foreign matter from entering the well.  A flowing artesian well shall be equipped with a shut-off valve and backflow preventable to that the flow of water can be stopped completely when the w ell in not in use.

All wells, except flowing artesian and dug wells, shall be vented.  The opening of the vent pipe shall be covered with a twenty four mesh corrosion resistant screen and shall be large enough to prevent water from being drawn into the well through electrical conduits or leaks in the seal around the pump when the pump is turned on.  Te vent pipe shall terminate in a downward position at or above the top of the casing.

All connections to a well casing made below ground shall be protected by either a pitless adapter or a pitless unit that complies with the most recent revision of National Sanitation Foundation Standard Number 56 entitled “Pitless Well Adapters”.

Above grade connections into the top or side of the well casing shall be at least twelve inches above the proposed finish grade or two feet above the level of the highest know flood, whichever is higher.  Above grade connections shall be sealed so that they are watertight.

The ground immediately surrounding the well casing shall be sloped downward and away from the well in all directions to eliminate the possibility of surface water ponding.


Upon completion of well construction, the well contractor shall disinfect the well.  If a pump is to be installed by the well contractor immediately upon completion of the well, the contractor shall disinfect the well and pumping equipment after the pump is installed

If the pump is not installed upon completion of the well, the pump contractor shall, upon installation, disinfect the well and the pumping equipment.  The pump contractor shall also disinfect the entire water supply system after any maintenance work or repair work is done to the pump.

When a well in disinfected, the initial chlorine concentration shall be 100 mg/l throughout the entire water column.

For newly constructed or altered wells in which the pump is not immediately installed, the chlorine concentration used to disinfect the well shall be 100 mg/l.  Upon installation of the pump disinfection of the well, the pumping equipment, and distribution system, if connected, shall be accomplished with a chlorine concentration of 100 mg/l.

The disinfectant solution shall remain, undisturbed, in the well for a minimum of two hours.  After all of the chlorine has been flushed from the water supply system, a water sample shall be collected by, and submitted to, a Massachusetts Certified Laboratory.  For new wells, the sample shall be tested pursuant to Section VI of these regulations.  For well which have undergone repair, the sample shall be tested for coli form bacteria and other parameters deemed appropriate by the Board.





Abandoned wells, test holes and borings shall be decommissioned so as to prevent the well, including the annular space outside the casing, from becoming a channel allowing vertical movement of water.

The owner of the private well shall decommission the well if the well meets any of the following criteria:


1.        Construction of the well is terminated prior to the completion of the well

2.        The well owner notifies the Board that the use of the well is to be permanently discontinued

3.        The well has, after extended use, been out of service for at least three years.

4.        The well is a potential hazard to public health or safety and the situation cannot be corrected

5.        The well is in such a state of disrepair that its continued use is impractical.

6.        The well has the potential for transmitting contaminants from the land surface into an aquifer or from one aquifer to another and the situation cannot be corrected.

The property owner shall be responsible for ensuring that all abandoned wells and test holes or borings associated with private well installation s are properly plugged.  Only registered well drillers may plug abandoned wells, test holes and borings.

In the case of new well construction, all test holes and borings shall be completely filled with clean sand.  The clean sand shall not leach chemicals, either organic or inorganic, that will adversely affect the quality of the groundwater where it applied.

The clean sand shall be introduced at the bottom of the well or boring and placed progressively upward to a level approximately four feet below the surface of the ground.  The remaining four feet at the top of the well or boring shall then be filled with concrete and the exposed casing shall be cut at a level six inches below the surface and covered with a concrete slab.  This concrete slab shall be at least six inches thick and shall be at least two feet greater in diameter than the well casing or bore hole wall.

Upon decommissioning any well, the well driller shall submit to the Board a “Report of Decommission” with ten day of completion.  The report shall include the following”

1.        Name, address and telephone number of the owner

2.        Name, address and telephone number of the well driller

3.        Location of well

4.        Reason for abandonment

5.        All of the well characteristics

6.        List of plugging materials used

7.        Plugging procedure used


      XI.            ENFORCEMENT

The Board shall investigate violations of these regulations and /or the Water Supply Certificate conditions, and may take such actions as the Board deems necessary for the protection of the public health and the enforcement of these regulations.

If an investigation reveals a violation of these regulations, or the Water Supply Certificate conditions, the Board shall order the private well owner to comply with the violated provision (s).

These orders shall be in writing and served in the following manner.

1.        Personally, by any person authorized to serve civil process, or;

2.        By any person authorized to serve civil process by leaving a copy of the order at the well owner’s last and usual place of abode, or;

3.        By sending the well owner a copy of the order by registered or certified mail, return receipt requested, if the owner is with the Commonwealth, or;






4.        If the well owner’s last and usual place of abode is unknown or outside of the Commonwealth, by posting a copy of the order in a conspicuous place on or about the premises and by advertising it for at least three out of five consecutive days in one or more newspapers of general circulation within the municipality whrin the private well effected is situated.


     XII.            HEARING

The private well owner to whom any order has been served may request a hearing before the Board by filing with the Board by filing with the Board within seven days after the day of the order is served, a written petition requesting a hearing on the matter.  Upon receipt of such a petition, the Board shall set a time and place for such a hearing and shall inform the well owner thereof in writing.  The hearing shall b e commenced not later than thirty days after the day on which the order was served.  The Board upon application of the well owner may postpone the date of the hearing for a reasonable time beyond such thirty-day period if in the judgment of the Board the well owner has submitted a good and sufficient reason for such postponement.

After the hearing, the Board shall sustain, modify, or withdraw the order and shall inform the well owner in writing of its decision.  If the Board sustains or modifies the order, it shall be carried out with the time period allotted in the original order or modification.

Every notice, order, or other record prepared by the Board in connection with the hearing shall be entered as a matter of public record in the office of the Town Clerk and in the office of the Board of Health.

If a written petition for a hearing is not filed with the Board within seven days after the day an order has been served or if, after a hearing, the order has been sustained in any part, each day’s failure to comply with the order as issued or modified shall constitute an additional offense.

   XIII.            APPEAL

Any person aggrieved by the final decision of the Board may seek relief there from within thirty days in any court of competent jurisdiction, as provided by the laws of this Commonwealth

   XIV.            PENALTIES

Any person who violates any provisions of these regulations, or who fails to comply with any order by the Board, for which a penalty is not otherwise provided in any of the General Laws, shall, upon conviction, be fined one hundred dollars.  Each day’s failure to comply with an Order shall constitute a separate violation.

    XV.            VARIANCE

The Board may, after a hearing, grant a variance to the application of these regulations when, in their opinion, the enforcement thereof would do manifest injustice, and the applicant has demonstrated that the equivalent degree of protection will still be provided to the private water supply without strict application to particular provisions of these regulation.

Every request for a variance shall be made in writing and shall state the specific variance sought and the reasons therefore.   The writing shall contain all of the information needed to assure the Board that, despite the issuance of a variance, the public health and environment will be protected.  Notice e of the hearing shall be placed on the Board’s posted agenda as an individual item for discussion.
