Assessment Report

Millhaven Creek

The purpose of an assessment report is to identify areas where drinking water sources are vulnerable to contamination or over use and to prioritize drinking water issues and drinking water threats within those vulnerable areas. Assessment reports are prepared in accordance with detailed technical rules set out by the Ontario Ministry of the Environment.

The Cataraqui Source Protection Committee worked over several years with Cataraqui Region Conservation Authority staff, consultants, local municipalities and others to prepare an assessment report for our area. The report was finalized in June 2011 and was approved by the Ontario Ministry of the Environment in October 2011.

The report will be updated in the future to reflect changing conditions in the Cataraqui Source Protection Area. The scope and timing of future updates will be determined in consultation with the Ministry.

The content of the document is being used to support the development of a Cataraqui Source Protection Plan by August 2012.
