Science & Plan
Scientifically Based Plans
The Sudbury Source Protection Plan identifies potential threats (as defined in the Clean Water Act and described in the Assessment Report) to municipal sources of drinking water and prescribes policies, actions and programs to reduce or eliminate these threats. The Source Protection Plan was originally approved on September 19, 2014 and became effective April 1, 2015. Updates under Section 36 of the Clean Water Act, 2006 were completed with an effective date of March 16, 2021.
The Explanatory Document provides the intent and rationale behind the policy decisions made in the Source Protection Plan.
Assessment Report
The Assessment Report contains technical information about surface and groundwater to inform the Source Protection Plan, including:
- Watershed Characterization
- Groundwater Vulnerability
- Surface Water Vulnerability
- Water Quantity Analysis
- Water Quality Threats and Issues
Approved Assessment Report Sections
The Assessment Report was approved on September 2014. Amendments were made on March, 16 2021 under Section 36 of the Clean Water Act, 2006. This notice provides a summary of the changes that were made.

Many other technical reports supported the development of the Assessment Report and Source Protection Plan. The list of reports can be found in the Assessment Report Appendices, all reports are available upon request.
Source Protection Plan - Annual Progress Report
Annually the Sudbury Source Protection Authority is required under the Clean Water Act, 2006 to report to the Ministry of the Environment, Conservation and Parks on the progress made throughout the previous calendar year in implementing the Source Protection Plan.
