Fairfield-Area PFAS Investigation
The Maine Department of Environmental Protection (DEP) continues to investigate the Fairfield area for the presence of per- and polyfluoroalkyl substances (PFAS) in the environment. The investigation began after the Department of Agriculture, Conservation and Forestry detected perfluorooctanesulfonic acid (PFOS) in an on-farm milk sample taken from an area dairy farm in June 2020. The Department began sampling groundwater at nearby area residences and installing water filtration systems at private residences beginning in January 2021.
For more information about PFAS and Maine DEP’s response to PFAS detected in groundwater and soil, please visit our main PFAS webpage.
Fairfield Sampling Information
Please visit the DEP’s interactive map (opens in new tab) to see where water samples have been collected in Fairfield, as well as in other areas statewide. Use the Search box to zoom to Fairfield, or type in an address.
Sample locations are identified as either above or below 20 parts per trillion (ppt), which is Maine’s interim drinking water standard. Clicking on sample locations will identify the concentration of PFAS detected in the sample. This map is updated as more information becomes available.
