Where can the maximum contaminant levels for contaminants be found?

The maximum contaminant levels (MCLs) for various contaminants can be found in state EPA environmental guideline documents. These documents are created to establish safe limits for contaminants in drinking water, ensuring that public health is protected. They serve as critical resources for understanding regulatory standards and compliance requirements applicable to water systems.

While the sample collector's handbook, monthly operation reports, and annual water quality reports provide important information about water sampling processes, operational data, and water quality over a specified period, they do not typically include the regulatory limits set for contaminants. Instead, those limits are specifically outlined in the state and federal guidelines that focus on water safety and public health. This makes the state EPA environmental guideline documents the most accurate and comprehensive source for finding MCLs.
