Associated Press — OKLAHOMA CITY (AP) -- Residents of an Oklahoma town are being asked to avoid drinking tap water until the local utility is sure that it has gotten rid of tiny red worms that wriggled into the water system.
Worms ranging from a half-inch to an inch long showed up this week in the water supply in Colcord, a small town near the Arkansas border about 80 miles east of Tulsa. Taking showers with the invertabrates is apparently OK.
City councilman Terry Wood said city water was turned back on Wednesday morning after workers cleaned, drained and re-cleaned the water tower. No worms were found in the tower, he said.
"We are still looking into this problem. I mean we need to get to the bottom of it and we will continue to investigate and do pretty much what we need to do to find out what happened here," Wood said.
Residents are being asked not to consume the water or use it to brush teeth or prepare food, Wood said, but it can be used for showers and other activities.
Erin Hatfield, spokeswoman for the Oklahoma Department of Environmental Quality, said it's uncommon for red worms to show up in a water system in the state, though it's fairly common in the southeastern United States.
She's not sure why or how the worms wriggle into water systems.
There are no adverse health effects with the red worms, she said, and the DEQ provided Colcord officials with recommendations for their water system to prevent future red worm infestations.
Red worms are considered a nuisance organism but not a health risk, said Alan Roberson, director of federal relations for the American Water Works Association. But, he noted, the idea of drinking water with worms in it certainly isn't appealing.
