PFAS (per-and polyfluoroalkyl substances), a group of more than 4,700 fully synthetic compounds that are widely used in industrial and manufacturing processes and found in many consumer products, persist through wastewater treatment at levels that may impact the long-term feasibility of "beneficial reuse of treated wastewater," according to a study conducted by researchers at Penn State and recently published in the Agronomy Journal.
PFAS (per-and polyfluoroalkyl substances), a group of more than 4,700 fully synthetic compounds that are widely used in industrial and manufacturing processes and found in many consumer products, persist through wastewater treatment at levels that may impact the long-term feasibility of "beneficial reuse of treated wastewater," according to a study conducted by researchers at Penn State and recently published in the Agronomy Journal.
PFAS, often referred to as "forever chemicals," are used to make fluoropolymer coatings and products that resist heat, oil, stains, grease and water, and are found in a variety of products from clothing and furniture to food packaging and non-stick cooking surfaces.
“PFAS are so pervasive and persistent that they have been found in the environment all over the world, even in remote locations,” said Heather Preisendanz, associate professor of agricultural and biological engineering at Penn State. “Unfortunately, these compounds have been shown to negatively impact ecological and human health, particularly because they can bioaccumulate up the food chain and affect development in children, increase risk of cancer, contribute to elevated cholesterol levels, interfere with women’s fertility and weaken immune systems.”
