What's New

Keep your eyes open for the new Drinking Water Protection Zone signs!
They are appearing across Ontario to protect public health and raise awareness of the sensitivity of our drinking water sources. More information is available in the Drinking Water Protection Zone Road Signs catalogue page in the Source Water Protection Education and Outreach catalogue on Conservation Ontario’s website. A page on Water Conservation has also been posted. It helps help homeowners and businesses understand their water use and gives tips on how to use less. We encourage you to view the new catalogue pages and promote them through social media at #SourceWaterON.

Visit the new Source Water Protection Map now available on Ontario.ca
NEWMARKET (February 5, 2016) - This interactive map provides the first provincial view of the more than 970 wellhead protection areas and 150 intake protection zones within the source protection areas in Ontario. You can access over 20 layers of information every time you do a customized search. It is available in: English and French. The public will be able to see the wellhead protection areas and intake protection zones of the lakes, rivers and aquifers that supply their drinking water, on a provincial scale map. This tool provides them with information needed to make informed property-based decisions. As well, this tool will help ministries and other agencies implement source protection plan policies. As well, a direct link to the map can be found in the updated General Messages page of the Source Water Protection Resource Catalogue available on Conservation Ontario’s website.

Drinking Water Source Protection in Ontario

The Clean Water Act
The Clean Water Act, 2006 is part of the multi-barrier approach of the Government of Ontario to ensure clean, safe and sustainable drinking water for Ontarians, by protecting sources of municipal drinking water including our lakes, rivers and well water. Under this legislation, the drinking water source protection program was established with funding from the Government of Ontario. This resulted in the development of science-based assessment reports and local source protection plans by multi-stakeholder source protection committees, who are supported by Source Protection Authorities.

Source Protection Plans
Source protection plans contain policies that either recommend or require that actions be taken to address activities identified as threats in the science-based assessment reports. The Government of Ontario has approved all 22 source protection plans, a significant milestone towards improved public health in Ontario. Implementation of all source protection plans is well underway across the province, by various implementing bodies including municipalities, provincial ministries and conservation authorities, to name a few.

Risk Management Services
Under the Clean Water Act, municipalities can appoint provincially trained and certified risk management officials (RMOs) to implement source protection plan policies requiring risk management plans (RMPs) and in a few instances prohibition, as a last resort. RMPs include measures to manage many activities like hazardous waste chemical storage, agricultural operations and road salt application in certain vulnerable areas. The measures could include the writing of spill response plans, operator training, signage, etc., and are negotiated between RMOs and landowners and renters, whoever is undertaking the activity. The monitoring of the measures is handled by risk management inspectors (RMIs). Municipalities can delegate the RMO and RMI function to others, including conservation authorities. Below is a list of conservation authorities undertaking risk management services in Ontario.
