Iowa American Water Lifts Precautionary Boil Advisory in Clinton

Clinton Customers no longer need to boil water before drinking or cooking

CLINTON, IA. (February 7, 2018) - Effective at 12 P.M. (NOON) today, Iowa American is lifting the precautionary boil advisory in its Clinton District. Water quality tests have confirmed that the water continues to meet all U.S. Environmental Protection Agency Safe Drinking Water Act and Iowa Department of Natural Resources regulations. It is no longer necessary for affected customers to boil their water before drinking or cooking.

During the boil water advisory, Iowa American Water performed a series of tests to determine if the water met regulatory drinking water standards. Multiple samples were taken from numerous sites throughout Clinton, and water quality tests have confirmed that the water meets all federal and state requirements.

The precautionary boil advisory was the result of a 16-inch water main break that occurred on Monday, February 5 in the 1400 block of 13th Avenue South in Clinton that impacted the entire community. Clinton customers are now being notified of the precautionary boil advisory lift via the company's automated CodeRED customer notification system.

Iowa American Water regrets the inconvenience this emergency water main repair work and precautionary boil advisory has caused its customers, and thanks them for their patience and understanding. The precautionary boil advisory was issued in accordance with Iowa Department of Natural Resources regulations as a safeguard to protect customers.
