Excess haloacetic acids detected in Thames Centre drinking water

The Middlesex-London Health Unit (MLHU) and the Municipality of Thames Centre have announced levels of haloacetic acids (HAA) in the town's water supply that exceed the province's maximum acceptable concentration. HAAs are a group of byproducts that can form in drinking water systems when chlorine compounds used as disinfectants react with organic materials in the water. There is no immediate health risk to people using the water for showering, drinking, and other purposes, officials say.
