The Iowa Department of Natural Resources (DNR) issued a boil advisory for Regional Water Rural Water Association customers this (Thursday) evening in five southwest Iowa counties, including Audubon and Shelby Counties. According to state officials, customers in the affected area are strongly encouraged to boil water before consumption due to an issue in the company’s distribution system that resulted in a loss of pressure. The order was issued as a precaution until whether bacteria infiltrated the lines can be determined. The DNR recommends customers bring all water to a rolling boil for at least one minute before use or utilize bottled water as an alternative. If water discoloration is not present in your home, tap water may be used for bathing, washing clothes, and other similar purposes. Staff worked quickly to repair and repressurize the water service lines, but it could take several days before water tests are returned. Affected residents are being notified via phone calls, the association’s website, social media, and local county Emergency Management Administrators. Customers with questions should reach out to Regional Water directly by calling 712-343-2413. Other counties affected by Thursday’s order include rural parts of Pottawattamie, Harrison, and Cass Counties.
