Be Well Informed is designed to help private well water owners understand their water test results. If their well water contains pollutants, the Be Well Informed application provides information about health concerns and water treatment choices relevant to their state, tribe, territory, or locality. This information is easily accessible through a simple, open-access web application.


The U.S. government estimates that more than 13 million American households rely on private wells for drinking water (U.S. Census American Housing Survey 2017). These wells are generally subject to little or no government regulation, making it essential that their owners understand how to test for and treat potential contaminants in their well water.


  • Accessibility: Provides the public with consistent, timely, and actionable information that is tailored to local standards
  • Public Health: Helps states, tribes, and territories create customized and clear explanations of health concerns and treatment options for chemicals and microbial contaminants
  • Costs and Timing: Minimizes development costs and reduces time to market by providing a customizable shared service
  • Data and Decision-Making: Helps private well owners understand complicated laboratory results and make more informed decisions about the need for additional testing or treatment


The New Hampshire Department of Environmental Services (NHDES) developed the initial Be Well Informed application with funding support from the Centers for Disease Control. NHDES then worked with E-Enterprise to modify the tool and make it available as a customizable shared service. To date, Alaska, Arizona, Massachusetts, Maryland, Michigan, New Hampshire, North Carolina, South Carolina, Virginia, West Virginia, and Wyoming, as well as Wake County, North Carolina, have officially adopted and tailored the tool to their jurisdictions. Other states, including Minnesota and Vermont, are testing the application and expect to publish their information to the application in the future.

The Environmental Council of the States (ECOS) began hosting this application in late 2020. To access the Be Well Informed app, go to in your web browser. There is no cost or login required — just click and go.


ECOS is working with current users of Be Well Informed and EPA’s Office of Water to improve the website with a new design and better usability. The new site will support a broader group of contaminants — including per- and polyfluoroalkyl substances (PFAS) — and will offer an enhanced user experience with new features and a more intuitive design.
