Update 15: DEP Expands Testing to an Additional Site in Brunswick

Maine Department of Environmental Protection
March 13, 2025

On January 23, 2025, the Department sampled the well located at the Mere Creek Golf Course, located southwest of the runway at the former Naval Air Station Brunswick. The concentration of the sum of six PFAS included in the Maine Interim Drinking Water Standard (PFOA, PFOS, PFNA, PFHXS, PFHPA, and PFDA) totaled 33.1 ng/L (same as parts per trillion or ppt). PFOS was 19.9 ng/L, which exceeds the new USEPA PFOS MCL of 4 ng/L (enforceable in 2029) as well as the Department of Defense's (DoDs) 12 ng/L criterion for initiating actions to address private drinking water wells impacted by PFAS from DoD activities.

Previous sampling of this well by the Navy and the Department in November 2015 and by the Navy in November 2021 showed the sum of 6 PFAS at concentrations of 20.85 ng/L and 19.21 ng/L, respectively. PFOS was the dominant PFAS in the samples.

The Navy has performed a cursory investigation of this general area of the base, but it is not detailed enough to determine whether the PFAS in the golf course well is a result of past Navy activities. The source of the PFAS in this well is currently unknown but predates the August 19, 2024 AFFF release from Hangar 4.
