EPA Announces New PFAS Rule And PWD Meets Standards
On April 10, 2024, the Federal government finalized national drinking water standards to protect communities from exposure to per-and polyfluoroalkyl substances (PFAS), also known as ‘forever chemicals.' The rule sets PFOA and PFOS Maximum Contaminant Levels at 4.0 parts per trillion, individually.
Most recently, the Greater Portland water system was tested in March of 2024, and no measurable amount of PFAS was found in the water. Also, PWD analyzed both the Greater Portland and Steep Falls water systems under Maine State rule in July 2022, and no measurable amount of PFAS was detected.
Per and polyfluoroalkyl substances, more commonly known as PFAS, are a class of chemicals that resist grease, water, oil, and heat; over 9000 different PFAS chemicals have been identified. They are found virtually everywhere in the environment because they have been used in many consumer products since the 1940s. Cookware with non-stick coatings, food packaging, carpets, cosmetics, furniture, and firefighting foam all contained PFAS and many still do.
PWD is committed to protecting public health and supports keeping PFAS out of the environment and efforts made to reduce PFAS at its sources, including keeping them out of consumer products. PWD is proactively engaged at the local, state, and national levels, exploring solutions to combat the widespread PFAS problem.
