The pair was hardly dressed like typical farmers, but this was no typical farm. Sporting white hazmat suits and respirators, Chelli Stanley and Richard Silliboy lugged 5-gallon jugs of water toward bushy plots of h**p, each 30-by-30-foot patch a stark sign of order in the otherwise overgrown field. It was a warm September day in Limestone, a small town on the edge of the Maine-Canada border, and the pair struggled to breathe in the head-to-toe protective gear. Stanley, a founder of the environmental organization Upland Grassroots, recalls telling Silliboy, vice chief of the Aroostook Band of Micmac Nation, “This will be worth it someday.”
For Stanley and Silliboy, the focus was not so much the h**p they were growing as what it was doing. Their farm, once part of the Loring Air Force Base, is also a Superfund site — an area so polluted it’s marked high-priority for federal cleanup. Later, when the Aroostook Band of Micmacs took over the site’s ownership, they found its soil was rife with per- and polyfluoroalkyl substances, better known as PFAS, cancer-causing compounds that are so difficult to break down they’re commonly known as “forever chemicals.”
Because of their ability to bind to proteins, PFAS tend to bioaccumulate — building up in soil, water, and even human bodies. Under typical environmental conditions, they can persist for hundreds, even thousands of years. But there is hope at Loring: In 2020, researchers discovered that the Micmacs’ h**p plants were successfully sucking PFAS out of the contaminated soil. This practice, known as phytoremediation, could guide farmers across the country who have had to shut down after discovering their soil is tainted with the ubiquitous class of chemicals.
