BATTLE CREEK, Mich. (WOOD) — Levels of a lingering harmful chemical group found in Battle Creek’s water have declined this summer, according to the city.
Samples conducted by the city of Battle Creek between early June and mid-July showed rising levels of total trihalomethane (TTHM), before the most recent round — collected July 24 — showed lower levels across multiple locations, the city said.

TTHMs form as compounds when disinfectants to treat drinking water react with naturally occurring organic matter in the water, according to the city. That can happen more quickly during hot weather.
“Prolonged exposure to high levels of TTHM over many years may affect the liver, kidneys or central nervous system and increase cancer risk,” the city previously said in a statement. “Although no precautions are recommended, if you or a member of your household have a compromised immune system, are an infant, or are elderly, you should consult your healthcare provider.”
