The Department has the statutory responsibility to protect public drinking water supply wells from pesticide contamination. Pesticide applications in drinking water recharge areas are regulated by provisions outlined in the Groundwater Protection Regulations (333 CMR 12:00). These regulations apply to pesticide products on the Groundwater Protection List. The Groundwater Protection List refers to a list of pesticide active ingredients that could potentially impact groundwater. This list is updated yearly by the Department. The use of pesticide products with active ingredients contained on the groundwater protection list in a drinking water recharge area is only allowed according to a Department-approved Pesticide Management Plan.
