An Act relative to setting NDMA levels

This bill directs the Massachusetts Department of Environmental Protection to establish specific safety limits for n-Nitrosodimethylamine, a chemical found in drinking water, to protect public health. It requires the department to review existing chemical guidelines and set a maximum allowable level for this compound, treating any water exceeding that limit as a regulatory violation. Additionally, the bill mandates that the department report annually to the state legislature on how often water samples are tested and how frequently they exceed the new safety standards. These changes directly affect residents of Massachusetts by ensuring their tap water meets updated safety criteria and increases transparency regarding water quality monitoring.
