Location Lookup for Arsenic and Uranium Probability Zones

Below are state-wide overview maps, as well as a listing of all of the towns that were either completely or partially located within the study area included in the USGS Study Report. The full title of the report is: "Scientific Investigations Report 2011-5013, Arsenic and Uranium in Water from Private Wells Completed in Bedrock of East-Central Massachusetts: Concentrations, Correlations with Bedrock Units, and Estimated Probability Maps."

State-wide Maps for Arsenic & Uranium Probability

Detailed Town Maps

The town listing includes towns that were outside the study area but include bedrock units that were in the study area and for which probability information is available. The listing also includes towns that are mapped as areas of granite or pegmatite bedrock units that were not included in the USGS study area, but may have an increased probability for containing radionuclide contaminants such as radon, radium and uranium.

Please note that not all of the towns listed below have increased probabilities of having arsenic and radionuclide contamination in private bedrock aquifer wells. Those towns with an asterisk were not identified with bedrock units having an increased probability of containing water with naturally occurring arsenic or uranium levels exceeding public drinking water standards. Furthermore, there are many towns on this list that are either mostly or entirely served by public water supplies rather than private bedrock wells.

Click on the links next to your town below to obtain a PDF map of the arsenic or uranium probability zones for your town. If your town is not included in the list below, then there is no arsenic and uranium probability information available your town. Please note that for many of these towns there are some areas for which arsenic or uranium probability information is not available.

* less than 100 acres granite and no areas identified with greater than 1% probability of exceeding the arsenic or uranium standard
