Section 1. DEFINITIONS
1-1 The word "Well" as used in these regulations, shall include any dug, drilled, driven or washed well or other source of water to be used for any purpose including supplying potable water in Carlisle. It shall include wells connected to heat pumps.
1-2 The words "water systems" as used in these regulations, shall included pipes, valves, fittings, tanks, pumps, motors, switches, controls and apprenticeship installed or used for the purpose of storage, distribution, filtration, treatment or purification of water for any use whether or not inside a building.
Section 2 WELLS
2-1 Permits: No well shall be installed until a permit has been given by the Board of Health or its agent. The fee for this permit shall be set by the Board from time to time.
2-2 Methods: The well contractor shall observe reasonable sanitary measures and precautions in the performance of this work in order to prevent pollution or contamination of the well.
2-2A Drilled Wells
2-2A-1 The well casing shall be schedule 40 - 6" steel pipe with a fitting at the bottom to seal the casing to the drill hole to keep out surface water.
2-2A-2 The casing shall be set a minimum of 12 feet into rock.
2-2A-3 A well casing or extension thereof shall extend vertically at least eighteen (18) inches above established ground surface, or above the floor of an approved pump pit.
2-2B Dug, Drive and Wash Wells less than 20 ft. shall have casing, tight all the way, for the total depth of the well. Wells over 20 ft. shall have a minimum of 20 ft. of casing, tight all the way.
2-2C Wells Penetrating Consolidated Rock
A hole of sufficient diameter to accommodate protective casing must be constructed and the annular space between rock and casing sealed to depth specified in this section.
2-2C-1 Sealing Material - The sealing material shall consist of neat cement, cement grout, puddle clay, or concrete. Organic polymer muds shall not be allowed. The neat cement mixture shall be composed of one bag of Portland Ceme t (94 pounds) to 5-to 7 gallons of clean water. Quick setting cement, retardants to setting and other additives including hydrated lime to make the mix more fluid (up to 10 percent of the volume of cement), and bentonite (up to 5 percent) to make the mix more fluid and to reduce shrinkage may be used. Concrete used shall be "Class" (6 sacks of Portland Cement per cubic yard) or "Class B" (5 sacks per cubic yard).
2-2C-2 Thickness of Seal - The thickness of the seal shall be at least one inch, and not less than three times the size of the largest coarse aggregate used in the sealing material.
2-2C-3 Placement of Seal - The sealing material shall be installed in one continuous operation from the bottom of the interval to be sealed to the top. The addition of a tight fitting rubber sealing plug is required. This pluck shall be used to push and hold the cement grout seal out of the casing and to seal the annular space for a twelve foot interval between the well casing and ledge or bedrock. The intent of the plug is to prevent the shear weight of the sealing material from forcing its way back into he casing and thereby resulting in a failed seal. (Effective 11/10/89).
2-2C-4 Sealing Casing into Bedrock - For all wells which terminate in bedrock, a permanent casing shall extend from eighteen (18) inches above the ground or floor of a pit into bedrock a minimum of twelve (12) feet below the bedrock surface.
2-3 Well for Each Dwelling: There shall be a separate well for each dwelling, and it must be 100 feet from all existing and approve proposed septic tanks, pump chambers and leaching fields including reserve fields. Wells must be set back at least 25 feet from all streets and lot lines.
2-4 Well Yield: Well yield shall be considered the smaller of the two (2) pump test measurements determining:
2-4-1 The gallons per minute of water the well is capable of delivering for a minimum of four (4) hours followed by
2-4-2 The gallons per minute of water the well recovers (based on drawdown and recovery) after a minimum of one and a half (1 1/2) hours.
2-5 Flow Requirements:
2-5-1 The minimum flow required for a washed well or well point shall be not less than 15 gallons per minute after a test pumping of one (1) hours.
2-5-2 A drilled well shall give the following gallons per minute as determined by the methods required in Sec. 2-4:
100 feet = 5 gallons per minute
200 feet = 3 gallons per minute
300+ feet = 2 gallons per minute
It is noted that these flows do not meet FHA and or VA requirements.
2-6 Drilller's Report: After completion of any water well, productive or non-productive, and before the issuance of a building permit, a registered well driller shall submit to the Board of Health a report containing the name of the owner of the well, location of the well, well depth, depth to bedrock or refusal, casing type, casing size and casing length, well screen type, well screen length, and well screen depth set, static water level, method used to test well yield, length of time (in hours) well pumped, draw down, well yield, length of time (in hours) well pumped, draw down, well yield, and drilling logs describing the material penetrated. Report forms may be issued by the Board of Health upon request.
2-7 Water Analysis: For all new wells and upon transfer from one owner to another, the Board of Health requires the submission of a water analysis report of the property's untreated water by a laboratory approved by the Board of Health or the EPA. Wells shall meet bacteriological requirements as specified in 310 CMR 22.00 (Mass. Drinking Water Regs) and in addition shall be tested for:
|
pH |
