The city of Madrid has been put on a boil advisory following a turbidity level of 4.39 units earlier this morning. The standard allowed is 1 turbidity unit or less.
High levels of turbidity can interfere with disinfection and increase chances that the water may contain disease-causing organisms. These organisms may include bacteria, viruses and parasites, which can cause symptoms such as nausea, cramps, diarrhea and associated headaches.
City staff is working on some filter media changes to resolve the problem, but expect the boil advisory to continue until the filter media can be replaced next week.
Residents should bring water to a boil, boil it for one minute and let it cool before using it for drinking, making ice, brushing teeth and preparing food. Tap water can be used for bathing and similar uses.
Boiling kills bacteria and other organisms. Bacteria in the water may pose greater health risks for infants, young children, some of the elderly and people with compromised immune systems.

The city or DNR will notify residents when the water is safe to drink.
