Boil Water Orders
Frequently Asked Questions
What does a boil order mean?
The tap water may have germs that can cause illness. This usually happens because of equipment failure, broken or leaking pipes, or low water pressure.
Does a boil water order mean there is lead in the water?
No. Boil water orders are typically issued as a precaution due to events such as water main breaks, maintenance, or temporary loss of water pressure. They do not automatically indicate the presence of lead or other contamination.
The City of Mt. Vernon’s water is tested regularly and meets state and federal standards. Information about lead service lines and the City’s replacement program is available on the City’s Lead Service Lines page.
I have already drank the water. Will I get sick?
Most people will not get sick. If illness occurs, symptoms may resemble food poisoning (nausea, diarrhea, cramps, mild fever). If concerned, contact your healthcare provider.
How long will the boil order last?
Until lab testing confirms the water is safe again.
