Water Science

The natural quality of Prince Edward Island groundwater is excellent. The challenge for all of us is to keep it that way.

Locals and visitors can observe the general health of a watershed and the water moving through it, but did you know that you can also download a watershed report card and compare the water quality of one watershed to another?

What factors are considered in the health of a watershed?

Nitrate concentration in streams, anoxic events, fish kills, siltation events and other factors are important gauges of the health of PEI watersheds.

Each year people see things in streams, ponds and estuaries that cause concern, but this does not mean that the water is polluted. Often, there is a natural cause for these conditions.

What is being done?

Research continues to ensure water quality and quantity remain high. UPEI, along with the Institut national de la recherche scientifique (INRS) in Quebec City, is studying the flow needs of aquatic life in PEI streams. This multi-year work will help government establish the best combination of stream protection and water use.

What you can do?

What we do on land, in our homes and communities, and in our waterways affects our local watershed. Be a good water steward.

During public consultations on the proposed Water Act Water Withdrawal Regulations, there were many questions relating to the quantity of water on PEI and the sustainability of its use. In response, a technical paper and bibliography has been prepared. Learn more about the science on PEI water.
