Unknown chemical in city's water triggers bottled water warning
Anamosa residents are being asked to drink bottled water after city officials say a chemical delivery to the eastern Iowa city's water system may have been mislabeled.
City Administrator Alan Johnson says Monday that the unknown chemical that entered the city's water supply may have been vegetable oil or soap, but it won't be known until water testing is complete.
The Iowa Department of Natural Resources is working to identify the chemical after a city employee noticed the chemical mixture that treats the city's water looked different Friday afternoon.
An automated system allowed one to three gallons of the chemical into the city's 750,000 gallons of water storage.
Officials will notify residents when the water is safe to drink.
Anamosa has a population of about 5,500.
