illustration of water drops soaking into the ground to become groundwater in an aquifer

I am groundwater and I'm worth protecting.

Waterloo Region relies on groundwater for drinking water. What we put on the ground can be harmful to groundwater. In the winter, this includes salt and ice melters including products labelled environmentally friendly.

  • Learn why salt is damaging to groundwater
  • Read the I Am Groundwater's blog "six mistruths about winter salt"
  • Snow and ice clearing tips for homeowners
  • Actions businesses can take to maintain winter safety and reduce salt use
  • Learn what the Region of Waterloo is doing to reduce the impacts of salt on groundwater
Groundwater's journey to your tap
  1. You can find groundwater in an aquifer. When it rain or the snow melts, the water soaks into the ground to fill the spaces between sand grains, rock or gravel in an aquifer.
  2. A pipe or well is put into the ground to collect the groundwater. The Region of Waterloo manages over 120 wells that supply groundwater to homes and businesses.
  3. After the groundwater is pumped up the well it is treated and tested before going through underground pipes to your home.

Help protect groundwater
  1. In the winter, shovel the snow first and limit the use of de-icing salt
  2. Report chemical spills
  3. Set your water softener to the correct water hardness to reduce salt use
  4. Reduce your water use by taking shorter showers, fixing leaky fixtures and using a rain barrel for outdoor watering
  5. Return unused and expired medications to participating pharmacies
  6. Only allow rain down the storm drain
  7. Clean with "green" alternatives and natural options whenever possible
  8. When using household chemicals, only buy what you need, use it up and dispose of leftovers safely and properly
