Downloadable Contaminated Site Lists

Downloadable Information on Waste Sites and Spills

These are some links and downloadable files you can use to further investigate Massachusetts Sites and Spills. These files contain information on the current status, notification information, location and many other details on these 40,000 plus sites in the state. We have both downloadable information and links to our online searchable database.
