(EC507/21) SCHEDULE C METHODS FOR DISINFECTING WELLS A well shall be thoroughly disinfected before it is placed into operation. The most commonly used methods involve chlorine, either in liquid or tablet form. The approved methods are indicated by the case descriptions below. (Note: Chlorine should always be used in a well-ventilated place, because breathing the fumes can be hazardous to a person’s health.) CASE A - WELL HOOKED UP TO A PLUMBING SYSTEM 1. Mix 1 litre of liquid laundry bleach or chlorine with approximately 45.5 litres (10 gallons) of water. Pour the solution directly into the well by removing the well seal or the well cap. 2. Open all faucets in the system and let the water run until the chlorine odour or taste is detected. Turn water off and repeat step #1 with a second chlorine solution. 3. Let the system sit for a minimum of 8 hours, and preferably overnight. 4. Discharge water from all outlets until the chlorine odour and taste has disappeared. Faucets or fixtures discharging to septic tank systems should be temporarily diverted to an outside discharge point to avoid overloading the disposal system. Page 28 Current to: September 20, 2025 t c Well Construction Regulations CASE B - AFTER WELL COMPLETION 1. Mix 1 litre of liquid laundry bleach or chlorine with approximately 45.5 litres (10 gallons) of water. 2. Pour the solution into the well, secure the well with an approved well cap and let the system sit for a minimum of 8 hours, and preferably overnight. (EC507/21) SCHEDULE D METHODS FOR FILLING UNUSED WELLS Unused wells, if left open or if insufficiently covered or filled, can be a potential source of groundwater contamination. In addition, wells dug by hand pose a potential safety hazard to the public, livestock and wildlife. The approved methods are indicated by the case descriptions below. CASE A - DRILLED WELLS All obstructions in the well shall be removed prior to filling the well. The well should then be filled with alternating layers of bentonite or cement and clean fill (clay till or sand). The bottom 3 m (10 feet) of the bore hole shall be filled with the bentonite or cement. The thickness of the individual layers of bentonite shall be not less than 0.3 m (1 foot) thick. The thickness of clean fill layers shall not exceed 1.5 m (5 feet). (Note: This plugging procedure is intended to prevent the vertical movement of contamination down the well bore hole. In addition, if the portion of the casing which is above ground becomes an eyesore or a safety concern, it can be cut off below the ground surface.) CASE B - DUG WELLS Any obstructions in the well (piping, pump, wooden material, etc.) shall be removed prior to the plugging of the well. The well shall be filled to within 1 m (3 feet) of the ground surface with a mixture of sandstone and clean fill material. A minimum 0.15 m (6 inches) thick layer of a low permeability material such as bentonite or compacted clay shall be installed within 1 m (3 feet) of the ground surface to prevent the entry of surface water to the water table. The surface area of the top of the well shall be covered with topsoil and graded in a manner that will allow drainage away from the well. CASE C - BOREHOLES FOR CLOSED-LOOP SYSTEMS c t Current to: September 20, 2025 Page 29 Well Construction Regulations Boreholes for closed-loop systems which will no longer be used shall be abandoned in a manner that complies with CAN/CSA C-448 – Series 13, paragraphs 4.5.1, (a), (b) and (c), developed by the Canadian Standards Association.
