There are some limitations to these data and their representation on these maps. First, depending on the zoom level of the map, some data points will not appear. These data points are on the map and can be seen by zooming in to a particular area (using the sliding scale on the left side of the map). Second, these data points should only be considered an "approximation" or "best estimate" of site locations based on the information submitted to the MassDEP. For more information please see the data limitations section of this page.

The source of this data is the Office of Geographic and Environmental Information (MassGIS), Commonwealth of Massachusetts, Executive Office of Energy and Environmental Affairs.

The data presented on this page is based on data published by MassGIS in May 2009.
