Nearly two dozen homes in Carroll have been placed under a boil advisory following a water main break last (Monday) night. According to Public Works Director, Randy Kraul, city crews discovered the break near the intersection of 9th and Adams Streets and quickly worked to correct the issue. However, 21 properties on Adams between 8th and 10th Streets were issued a boil advisory as a precaution. All water for consumption, including drinking, making ice, brushing teeth and other similar purposes, must be boiled for at least one minute before using. Impacted residents have been directly notified by city staff. The advisory will remain in effect for at least 48 hours from issuance to allow time for testing to determine the water is clear of bacterial contamination. Residents with questions can contact the Carroll Water Department at 712-792-1000.
