Welcome to MassDEP - the Massachusetts Department of Environmental Protection. The environment matters to all of us who live, work and play in Massachusetts and through this Web site we hope to keep you informed about and involved in the work we do to protect our environment.

This Web site is your gateway to information about the work MassDEP does to ensure clean air and water,  the safe management of toxic and hazards, the recycling of solid and hazardous wastes, the timely cleanup of hazardous waste sites and spills, and the preservation of wetlands and coastal resources. It is also a place to find out about environmental matters in your community, to conduct business on-line with MassDEP through our Service Center, and to participate directly in our environmental protection work.
