Section 20.7.10.600 - PUBLIC NOTIFICATION

A. Non-transient non-community water systems that exceed the MCL for arsenic or radionuclides set forth at 40 CFR sections 141.11, 141.62 and 141.66 or exceed one-half the MCL for fluoride set forth at 40 CFR section 141.62 shall comply with the public notification requirements set forth at 40 CFR Subpart Q.

B. A supplier of water shall notify persons served by the public water system to boil water used for drinking or culinary purposes if routine coliform samples indicate the presence of bacterial contamination which would not otherwise trigger the public notice requirements set forth at 40 CFR Subpart Q but which, in the judgment of the department, poses a threat to public health and safety. If the supplier of water fails to provide notice on its own, or at the direction of the department, the department may directly notify the persons served by the system.

C. If the safety of a water supply is endangered for any reason, the supplier of water shall notify persons served by the public water system of appropriate action to protect themselves against any waterborne hazards. If the supplier of water fails to take such action on its own, or at the direction of the department, the department may directly notify the persons served by the system.
