The Machias selectboard learned at its Feb. 12 meeting that a former 2.5-acre municipal landfill from 1930 until capped in 1996, is leaching per- and polyfluoroalkyl, or PFAS, substances near and possibly into the Middle River marsh behind the site, adding yet another complication to the seesaw battle over the future of the Machias dike replacement. 

The Machias landfill occupied an area near the Marshfield town line, behind the current transfer station off Broadway.
