O’FALLON, IL (KMOX) - It may still smell funny but it is safe to drink.

That’s what O’Fallon, Illinois’ Public Works Director is saying about the city’s water, which started emitting an odor last week. Dennis Sullivan says low levels on the Mississippi River have caused the water to become more turbid.

“Basically, that’s the small particles in the water,” Sullivan explained. “You can’t see them but they’re there though. If you had the ability to settle them out, you’d see them and with those come an odor.”

But Sullivan says the supplier, Illinois American Water, has the best labs in the country and has determined it is safe to drink. “I have no qualms about the quality, the drinking quality, of drinking water. Unfortunately, it’s aesthetically not as pleasing as it is normally.”

As for the odor, Sullivan said that won’t improve until river levels rise.
