The Ohio Environmental Protection Agency (OEPA), through the State Primary Drinking Water Regulation, regulates water utilities and specifies instances when an advisory or notice must be issued.
A precautionary advisory must be issued in the following instances:
- If untreated water reaches the distribution system
- Loss of pressure in the entire distribution system or a significant portion of the system
- A water main break where dirt and debris have entered the distribution piping
A Boil Water Notice must be issued under the following circumstances:
- When test samples indicate the presence of total coliform bacteria.
These situations are not the only times when a precautionary advisory or notice should be issued. Specific situations, upon consultation with OEPA, may also require a precautionary advisory or notice.
