Water Discolouration: Tri-County Water Board

Water Discolouration: Tri-County Water Board
The Tri-County Water Board is aware of coloured water being detected by some residents who are on the Tri-County Drinking Water System and rely on Lake Erie for their raw water source.
This discoloured water is being caused by elevated concentrations of manganese and iron in Lake Erie. Manganese and iron are naturally occurring minerals present in source water, and weather conditions can impact the concentration of these minerals in the Lake. Please note, that although unpleasant, the discolouration is an aesthetic issue only. The water is regularly tested by our drinking water operator, the Ontario Clean Water Agency (OCWA), and meets the provincial drinking water regulations set out by the Ministry of the Environment, Conservation, and Parks (MECP). Operational changes have now been made by OCWA to help alleviate the effects, and weather conditions have improved and continued to be monitored. As the conditions improve, the distribution systems will be flushed of the coloured water and you should notice a return to normal colour.
