Water Discoloration Update - Tri-County Water Board 

Tri-County Water customers may continue to notice a discoloration and/ or slight odour. This is caused by elevated concentrations of manganese and iron in Lake Erie which is stirred up by lake turnover and weather. Manganese and iron are naturally occurring minerals present in the source water. The water is regularly tested and continues to meet all provincial drinking water regulations set out by the Ministry of the Environment, Conservation and Parks (MECP).

The Operating Authority (OCWA) at the Tri-County Water Treatment Plant has put in place operational changes to deal with the change in the intake water and they are continuing to monitor and adjust the treatment processes to provide safe drinking water.

This issue has affected most water treatment facilities on the north side of Lake Erie and some in the USA. It is anticipated that the incoming lake water will improve the colour and odour issues shortly as some improvements have been seen.
