Does The Water Industry Have What It Takes To Meet EPA's Proposed Tough Restrictions On PFAS?

In March, the EPA announced a proposed National Primary Drinking Water Regulation with maximum contaminant levels (MCLs) for PFOA and PFOS of 4ppt each. The announcement was a surprise to the industry, which was anticipating levels of 70ppt for these two most common per- and polyfluoroalkyl substances. With this announcement, the EPA is clearly looking at water systems to shoulder the hard and expensive work of testing and treating for PFAS. Water systems, in turn, are looking to engineers and water equipment suppliers to provide the technology and expertise that such a job will require.

Luckily, the water industry has always been able to step up when the need arises by collaborating and innovating. Keep reading to explore the current treatment technologies, what is already working, and how we can achieve cleaner water.
