Precautionary Boil Water Notice

Environmental Health

A precautionary boil water notice is issued to protect consumers when it is possible that drinking water has been contaminated by microorganisms that can cause illness (i.e. germs or pathogens). Common reasons for a boil water notice include loss of pressure in the water distribution system, loss of disinfection, and other water quality concerns caused by other events such as water line breaks, power outages and floods.

The Florida Department of Health has issued Guidelines for the issuance of precautionary boil water notices to protect the public from exposure to drinking water contaminants that may have entered a drinking water distribution system during this events. These guidelines address what actions to take for instances of loss of power, natural disasters, microbiological contamination, low pressure and water line breaks.
 
A public water system can issue its own precautionary boil water notice using these guidelines, but the FDOH-Hillsborough County office and the public must be notified no later than 24 hours after the water system learns of the situation.
