[Adopted 6-7-1988]
No person or firm shall engage in the construction, alteration, installation or repair of any private domestic drilled well until a water systems installer permit has been obtained from the Board of Health. The well installer shall be licensed by the Franklin Board of Health annually with the permit expiring December 31. The fee for this permit shall be set by the Board from time to time.
A plot plan shall be submitted with the application form for a well permit to the Board of Health, indicating the proposed location of the well, all buildings, boundary lines and septic systems. Wells shall be located at least 15 feet from any public or private way or street and 10 feet from lot lines, 50 feet from any septic tank and 100 feet from any leaching system or any other such greater distance as may be required by the Board of Health.
A well drilled into the bedrock shall have a minimum depth of 100 feet below the static water level, and the casing shall extend no less than 18 inches above the normal ground level. A mounding of at least eight inches shall be implemented around the casing. A well located in a floodproofed well house will not require mounding. The casing shall be sealed at least 15 feet into the bedrock by use of a slurry of 50% bentonite and 50% clear portland cement.
Quantity or yield tests and water level recovery shall be performed by a licensed pump or well-drilling contractor, and a well shall produce a minimum supply for each dwelling unit served by an on-site well as follows:
Well Depth
(feet)
Minimum Supply
(gallons per minute for 4 hours)
100 to 150
5 to 8
150 to 250
3 to 5
250 to 350
2 to 3
350 to 400
No less than 2
The water from a potable well shall be sampled following development. Chemical and bacteriological analysis shall be made, and approval of the Board of Health must be obtained before an occupancy permit is issued.
Two representative samples of water shall be collected, one from the well site and the other from the tap in the building, by a laboratory certified by the Massachusetts Department of Environmental Quality Engineering and results of the report forwarded to the Franklin Board of Health.
A drilled well abandoned for a period of one year shall be plugged and sealed with a slurry of portland cement at least 20 feet below the normal ground level to prevent surface contamination into the bedrock acquifers.
Any variance or other modification authorized to be made by this chapter may be subject to such qualification, revocation, suspension or expiration as the Board of Health expresses in its grant. A variance or other modification authorized to be made by this chapter may be otherwise revoked, modified or suspended in whole or in part only after the holder thereof has been notified in writing and has been given an opportunity to be heard.
