PFAS in Drinking Water: What the New EPA Rules Mean for Your Office

PFAS are found in the blood of nearly all Americans, according to CDC studies. These chemicals have become widespread in our environment and our bodies.

I work in the water business, so I'm biased. But the implications of this contamination are significant.

The Rules Just Changed

The EPA has established enforceable Maximum Contaminant Levels (MCLs) for six PFAS chemicals in drinking water. Public water systems have until 2027 to start monitoring and 2029 to comply with the limits.

Your office water system? It's probably not ready.

PFAS do not break down naturally in the environment or human body. They're called "forever chemicals" for a reason. Once they're in you, they stay.

What This Means for Your Office

Starting in 2027, public water systems will be required to monitor for PFAS and notify the public of PFAS levels.

But here's what nobody talks about: most office buildings have water systems that were installed before anyone cared about PFAS. The building might be new, but the approach to water treatment is old.

I see this constantly in Greater Madison offices. They have beautiful breakrooms with fancy coffee machines, but they're pulling water through systems that weren't designed to handle today's contamination challenges.

The Productivity Connection

Here's where it gets interesting. Research shows that most employees believe their employer should support their physical health and well-being.

Most companies spend thousands on wellness programs while ignoring the water their team drinks eight hours a day. Proper hydration can significantly improve workplace productivity, as dehydration affects cognitive performance and concentration.

But if your office water contains PFAS, you're not just dealing with dehydration. You're dealing with chemicals that accumulate in the body and don't leave.

The Real Problem

The EPA's new rules are good. They're necessary. But they only apply to public water systems. Your office building's internal water treatment? That's on you.

Most offices are running on assumptions that made sense in 2015. The water comes in clean, we add some basic filtration, everyone's happy. But PFAS changes that calculation completely.

These chemicals pass through most standard filters. They require specific treatment technologies that most buildings don't have.

What Actually Works

Point-of-use systems with the right filtration can handle PFAS. But you need to know what you're buying. Most "water coolers" aren't designed for this.

I install bottleless purified water systems because they work. The filtration is built to handle today's contamination challenges, not yesterday's.

But whether you go bottleless or not, the key is understanding what's actually in your water and having systems designed to deal with it.

The 2027 monitoring requirements are coming fast. Your team is drinking water every day that might contain chemicals found in nearly all Americans' blood.

That's not a wellness program. That's a problem that needs solving.
