Well database

View records about wells in Massachusetts, including location, well depth, and condition. Data spans 1962 to present day.


The Massachusetts Department of Environmental Protection (MassDEP) Well Driller Program has created a database of wells in Massachusetts. This data is used by the well drilling industry; local, state and Federal government; and the general public.  

The database includes drinking water wells, irrigational wells, geothermal wells, and industrial wells. You can search the wells database by City/Town, Well ID, well type, date range, or the kind of work performed (e.g. “decommission,” “new well,” “replacement,” etc.). Records include well depth, construction, and location.

About the data

We make a great effort to maintain the quality of this data. However, be aware that most records have been collected and entered by hand since 1962. More recent records have been entered electronically by drillers themselves.

The information collected for each record has changed since we first began collecting it. For example, latitude and longitude have only been required for the last 15 years. In the future, we’ll begin tracking down location data for records that don’t have it.

If you are a well driller, filling in accurate data, including the location data for wells you drill and are required to report as required under 310 CMR 46 will help us provide viewers accurate data.
