Ministry of The Environment, Conservation And Parks Documents Out For Comment On Drinking Water Resource Library
Two of the Ministry of Environment, Conservation and Parks (Ministry) documents that are out for public comment are now available for access on the Walkerton Clean Water Centre (WCWC) Drinking Water Resource Library, at www.DrinkingWaterResourceLibrary.ca. This includes the proposed amendments to the Watermain Disinfection Procedure (WDP, 2015) and a draft Terms of Reference: Determination of Minimum Treatment for Municipal Residential Drinking Water Systems Using Subsurface Raw Water Supplies. These documents are both available for discussion purposes only.
The amendments to the WDP were developed with a large stakeholder group composed of municipal representatives, Ontario Water Works Association, Ontario Municipal Water Association, Ontario Clean Water Agency and Ministry staff. Amendments were identified through requests for clarification and relief related to new/planned watermain construction and replacement.
The Terms of Reference document is aimed to be used to determine whether a subsurface water supply requires treatment beyond a minimum level of disinfection required to inactivate or remove viruses and bacteria, i.e. whether or not treatment for protozoa is required.
Any comments or need for further information can be addressed to the following:
