What is a Wellhead Protection Area (WHPA)?

A Wellhead Protection Area (WHPA) is the area of land surrounding a municipal well, which contributes water to the well. Within the WHPA, protective measures are implemented to safeguard the underlying groundwater supply from potential contaminant sources.

A municipal well taps into the water-bearing unit (or aquifer) found below the ground surface and draws groundwater from this unit for the municipal water supply system. Since this water must be distributed to these rural communities as clean and safe drinking water, it is important that the Region protects the source aquifers.
