Coalition for Safe Drinking Water

About the Coalition

The Coalition for Safe Drinking Water is a group of diverse individuals and organizations advocating for equitable access to safe drinking water for private well owners across Massachusetts.

Led by RCAP Solutions and The Health Foundation of Central Massachusetts, the goal of this grassroots effort is to effect change by moving the state legislature to enable the Massachusetts Department of Environmental Protection (MassDEP) to enact sensible, health-based protections for private wells and to offer financial resources for homeowners who discover contaminants in their well water.

Unlike with public water systems, there are currently no statewide regulations to ensure private well water is safe from contaminants like PFAS, arsenic, radon, and more. This problem can be solved, but it will take leadership from community advocates, non-profit organizations, legislators, and others.

Why Are Statewide Private Well Regulations Needed?

Article 97 of the Massachusetts Constitution established “the right to clean air and water” in 1972, and the United Nations declared safe and affordable drinking water as a human right in 2010. Statewide legislation is needed to provide similar protections for residents relying on private wells as for residents served by public water systems.

  • Over 500,000 residents in Massachusetts rely on private wells for their drinking water, yet there are no statewide regulations to ensure their water is safe and free of contaminants such as PFAS, arsenic, radon, uranium, and more.

  • In contrast, public water systems are subject to MassDEP Drinking Water Regulations (310 CMR 22.00), which set enforceable legal standards for water quality by which public utilities are required to comply.

  • Unlike public water systems, private wells are not subject to statewide requirements for routine water quality testing.

  • Currently, MassDEP can only issue recommendations for private wells and only local Boards of Health (BOH) have the authority to establish regulations, many of which are outdated or unused. MassDEP released model BOH regulations for private wells in 2018, but they have not been widely adopted.

  • Private wells span the Commonwealth, thus there is a statewide need for change. The total number of Massachusetts towns in which 60% or more residents rely on private wells is 84.
  • Contaminants in private well water may be naturally occurring or manmade. Contaminants such as arsenic, E. coli, radon, and uranium may have short-term and/or long-term health impacts.

  • MassDEP reports that high levels of arsenic, a human carcinogen, have been found in Hampden, Worcester, and Middlesex counties.

  • A 2011 U.S. Geological Survey study estimated that about 3,300 and 5,700 private wells in east-central Massachusetts may contain uranium and arsenic, respectively, at levels that exceed state and federal standards.
Massachusetts Maximum Contaminant Levels (MMCLs) are a set of guidance levels for various contaminants that could potentially be found in drinking water. These levels are based on U.S. Environmental Protection Agency (EPA) federal standards for drinking water, though MassDEP has adopted more stringent standards in some cases.

There are several potential health problems that can occur if contaminated water is consumed. In addition, contaminants may impact the aesthetic of drinking water (e.g., taste, color, odor) or a home's infrastructure.

Per- and polyfluoroalkyl substances (PFAS) are a class of thousands of synthetic chemicals used to make products resistant to water, heat, and stains. Often referred to as "forever chemicals", there is growing concern that PFAS in drinking water can have negative health impacts.

The ongoing MassDEP PFAS Private Well Testing Program has found that ~5% of private wells tested across Massachusetts have PFAS exceeding state health standards.
Many people who discover contaminants in their wells resort to drinking bottled water, which is expensive. Plastic also harms the environment; 80% of plastic water bottles used in the United States end up in landfills.
Residents who live in municipalities with public water systems or with local private well regulations are more likely to have access to safe drinking water than residents who don't.

Private Well Program to Protect Public Health Uncovers Contaminants

Many Massachusetts residents are consuming water that may be unsafe. From 2020 to 2022, RCAP Solutions conducted 502 water quality tests across several Massachusetts towns which had a high concentration of private wells. We discovered that approximately 32% of wells had levels of contaminants exceeding state health standards and/or suggesting potential health risks.


Wells that had levels of contaminants exceeding state health standards and/or suggesting potential health risks

Wells that did not have levels of contaminants exceeding state health standards and/or suggesting potential health risks


In comparison, 2020–2022 data from MassDEP shows that only about 4.5% of community public water systems (PWS) throughout the state had instances of contaminants exceeding state health standards and/or suggesting potential health risks. These results show that sensible, health-based regulations and oversight for drinking water wells would lead to a public health benefit.
