An Act relative to setting NDMA levels

This bill requires Massachusetts' Department of Environmental Protection (DEP) to establish safe maximum levels for NDMA (n-Nitrosodimethylamine), a chemical found in drinking water, to protect public health. It directly affects public water systems, which must test for NDMA and report levels exceeding the new limits to the DEP. The DEP must enforce these limits by treating violations as breaches of existing drinking water regulations and provide annual reports to the legislature detailing testing results and exceedances. The law aims to standardize monitoring and response for NDMA in the Commonwealth's water supply.
