Flint officials say previously high levels of a chlorine byproduct that can cause liver issues and even cancer if it’s ingested in high quantities over many years, are back down to safe levels in city drinking water.
The city had to send out a notice in November to residents letting them know that tests showed there were potentially unsafe levels of trihalomethane (TTHM) in the water.
The city pumped a lot of chlorine into the water after fecal bacteria turned up in water tests last summer, prompting a boil water notice.
Now that the TTHM levels are back under control, the city is still required to send out a notice letting residents know the results of this month’s testing because of the November violations.
