How often should non-public water systems be tested?

Non-public water systems should be tested at least annually to ensure they meet safety and quality standards. Regular testing helps identify any contaminants or changes in water quality that could pose health risks to consumers. This frequency is recommended to monitor potential issues that can arise from environmental factors, system maintenance, or changes in local regulations. Annual testing provides a proactive approach to safeguarding public health by detecting and addressing any problems before they become significant threats.

In the context of non-public water systems, which do not fall under the same regulatory requirements as public systems, relying solely on less frequent testing could lead to undetected contamination and subsequent health hazards. Therefore, the annual testing requirement underscores the importance of consistent monitoring in maintaining safe drinking water standards.
