    The Underground Injection Control Program protects groundwater sources by regulating the injection of fluids from drains and other underground outlets into these sources.

  • What You Need to Know about Microbial Contamination  doc format of What You Need to Know about Microbial Contamination

    Bacteria, viruses, and protozoa can cause a number of waterborne diseases when ingested through your drinking water. Find out what protective measures you can take to control contamination.

  • The Massachusetts Water Management Act Program

    The Water Management Act (M.G.L. c. 21G) became effective in March 1986, authorizing MassDEP to regulate the quantity of water withdrawn from both surface and groundwater supplies. The program uses the WMA to ensure adequate water supplies for current and future water needs.

  • Model Water Use Restriction Bylaw/Ordinance (2009)

    The Department of Environmental Protection has developed the "DEP Model Outdoor Water Use Bylaw/Ordinance" to help municipalities and water districts implement seasonal conservation of water supplied by public water systems (PWS). The Model Bylaw also includes options for regulating private wells and in-ground irrigation systems.

Source Water Assessment & Protection Program (SWAP)

  • Overview of the Source Water Assessment & Protection Program

    The Source Water Assessment and Protection (SWAP) Program was conducted several years ago.  The potential sources of contamination identified in the reports and the recommendations provided by MassDEP to public water systems to address them are still useful as a basis for local water supply protection planning and for developing a surface water or wellhead protection plan.  To request an updated SWAP GIS map, contact MassDEP’s Drinking Water Program at program.director-dwp@state.ma.us or 617-292-5770.
