It's time for a salting shift

Waterloo Region relies on groundwater for drinking water. Over time the salt we put on the ground can end up in our drinking water and cause it to taste salty.

After the salt melts the ice, it doesn't go away. It may soak into the ground to mix with groundwater (our drinking water) or enter a storm basin that connects with the local waterway.

Why salt is a water quality concern

Chloride levels from salt and ice melter are increasing in groundwater wells (our drinking water). Overtime this could make our drinking water taste salty.
Chloride is highly soluble. Once it dissolves in water there's really no effective way to remove it. Current water and wastewater treatment does not remove chloride from the water.
A salty taste is detectable when chloride levels reach 250 milligrams per litre. The below image shows chloride levels in Region of Waterloo municipal groundwater wells between 1998 and 2018.
