Nine rounds of surface water results from the Merriconeag Stream watershed, documenting conditions following the August AFFF release, have been evaluated by Department staff. Most concentrations continue to decline throughout the watershed, and the highest concentrations are still being detected below the Picnic Pond outflow. Four rounds of data from Harpswell Cove have been received by the Department and indicate contamination has reached the marine environment but is quickly being diluted to low concentrations. PFAS levels in the watershed have not yet returned to pre-spill concentrations and testing of surface water will continue to track the trends.
Update 12: Sampling effort continues for the former Brunswick Naval Air Station
