In the Cataraqui Source Protection Area (CSPA), about 80 per cent of residents (approximately 170, 000 people) rely on municipal drinking water systems that draw on surface water or groundwater. The other approximately 40, 000 residents in the CSPA obtain their drinking water from private intakes or wells.

 

Drinking Water Protection Road Signs

New road signs are in place to identify zones along frequently travelled roads where accidental pollution spills could travel quickly to a public drinking water source and contaminate it. These signs are standard in Ontario and are to alert emergency first responders that a drinking water source is nearby and to increase public awareness of the drinking water protection areas.

Municipal Residential Groundwater Supplies

Three municipalities in the CSPA own drinking water supplies that serve residential uses:

The Assessment Report delineated wellhead protection areas (WHPAs) for each of the municipal wells. It also determined the well’s vulnerability to contamination from activities that are currently taking place (or that could take place in the future) in the wellhead protection areas and are termed “drinking water threats” as per the Clean Water Act.

Municipal Residential Surface Water Supplies

Eight communities in the CSPA get their drinking water from a lake or river:

The Assessment Report delineated intake protection zones (IPZs) for each of the surface intakes. It also determined the intake’s vulnerability to contamination from activities that are currently taking place (or that could take place in the future) in the intake protection zones and are termed “drinking water threats” as per the Clean Water Act.

Regionally Sensitive Groundwater Areas

Some residents in the CSPA are not connected to a municipal drinking water system, and instead rely on groundwater drawn from private wells. The Assessment Report identified regionally sensitive groundwater areas across the CSPA, which are called highly vulnerable aquifers and significant groundwater recharge areas. More than 90 per cent of the CSPA is considered to be a highly vulnerable aquifer and/or a significant groundwater recharge area.
