Understanding My Laboratory Results

Overview and instructions on how to use the Be Well Informed website.


Be Well Informed (BWI) is an online tool hosted by Environmental Council of the States (ECOS) that allows you to enter your water quality lab results and obtain information regarding any contaminant concentrations that exceed MassDEP or federal standards or guidelines that exist for public drinking water.  The tool also provides information about any potential health risks and recommended water treatment options.

The BWI tool can be accessed at https://bewellinformed.info.


  1. In the Be Well Informed box click on the dropdown menu arrows in the box with the word "Select..." in it and select "Massachusetts", then click on the blue "go" box.
  2. A data entry page will open for the entry of your water quality results.
  3. There is also a "Resources" menu item at the top of the data entry page where you may obtain links to information relevant to private well owners.
