Unless granted a waiver by the state, how many coliform samples are required per month for a water system serving a population of 25 to 100?

For water systems serving a population between 25 and 100 individuals, the required number of coliform samples per month is specified by regulations to ensure safe drinking water. In this case, only one sample is needed each month. This standard is established to monitor water quality and identify potential contamination, while still being manageable for small systems that might not have extensive resources.

The regulatory framework acknowledges that smaller systems operate under different conditions compared to larger systems and therefore sets requirements that are more approachable yet still protective of public health. This approach helps ensure that water systems can comply without being overburdened, while also maintaining necessary health standards.

Understanding these requirements is crucial for water system operators to ensure they are monitoring water quality effectively and complying with state regulations.
