What is one cause that would require a Public Boil Water Notice?

A Public Boil Water Notice is a communication issued to inform consumers that they should boil tap water before using it for drinking or cooking. This notice is primarily required when there is a potential risk of microbiological contamination in the water supply.

Microbiological contamination includes the presence of pathogens such as bacteria, viruses, and parasites that can pose significant health risks. These organisms can enter the drinking water supply due to various factors, including breaches in the distribution system or failures in treatment processes. When there is evidence or suspicion of such contamination, public health officials issue a boil water notice as a precautionary measure to protect consumers from waterborne illnesses.

While other factors like low pH, excessive chlorine levels, and high turbidity can affect water quality and safety, they do not directly necessitate a boil water notice in the same way microbiological contamination does. For instance, low pH might indicate corrosivity but does not inherently pose an immediate health risk that necessitates boiling water. Excessive chlorine can make water taste or smell unpleasant and may indicate treatment issues but typically does not require boiling. High turbidity can signal particulates in the water but does not automatically mean there is pathogenic contamination present. Therefore, microbiological contamination stands out as the primary reason for
