Potential detection of toxic algae caused a tap water drinking ban in Greenfield, Iowa, pending water testing.
Greenfield Municipal Utilities announced the ban via their Facebook page after microcystin — a toxin produced by blue-green algae — was potentially detected in their drinking water. A sample collected Tuesday has been sent to a lab.
Lake Greenfield, a main source of drinking water for Greenfield Utilities, has been experiencing a harmful algal bloom (HAB), according to a release.
Pending return of a clean sample, Greenfield customers, including pets, are told not to drink the water, even if the water is boiled. People are told to find alternative water for making instant formula and ice, brushing teeth and preparing food.
