Dive Into St. Clair River Drinking Water

Restrictions on Drinking Water Consumption, Taste or Odor Problems, due to spills that have the potential to contaminate the river water requiring the shutdown of the drinking water intake facilities.

It is important to note the drinking water supplied by the water filtration facilities, using the St. Clair River as source water, have always met and/or exceeded all Federal and State drinking water guidelines. The St. Clair River Area of Concern impairment exists only because of the potential for contamination from spills and the need to shutdown facilities to avoid contamination.

There is a multi-level and international approach in place to protect our source water, giving us confidence that our drinking water is protected from potential spills and contamination. To address the impact of spills on drinking water filtration facilities, the following measures have been implemented:

  1. Discharges and spills from industrial sources have been greatly reduced since the 1980’s
  2. Discharges and combined sewer overflows from municipalities have also been reduced or eliminated
  3. Spill reporting programs have been updated for immediate real-time spill notification to facilities including the State of Michigan and the Canadian Spills Action Center
  4. Procedures for coordinated containment and clean-up response to spill events are in place and are routinely practiced
  5. Enhanced monitoring of intake water by water facilities to detect any exceedances of normal water chemistry
