The Ministry of the Environment is seeking public comment on a draft manual on test holes and dewatering wells. A “test hole” is a type of “well” that is made to obtain information about groundwater, and is not used or intended for use as a source of water for consumption. It includes virtually all the boreholes that are used to monitor groundwater quality or quantity, including contamination.
The draft Test Holes and Dewatering Wells: Requirements and Best Management Practices manual provides a plain language summary of the Wells Regulation (O. Reg. 903/90) and other legislation on test holes and dewatering wells. It provides best management practices on test hole and dewatering well siting, construction, maintenance and abandonment.
Comments may be made between December 10, 2012 and April 09, 2013.
