Most Americans Have PFAS in Their Blood. Your Office Water Might Be Why.
The CDC's ATSDR states plainly that nearly all people in the United States have measurable amounts of PFAS in their blood.
Let that sink in. These "forever chemicals" are in nearly every single person in this country.
Full disclosure: I sell water systems for offices. But that doesn't change the reality here.
Your Office Water System Isn't Helping
Most offices still rely on municipal water or basic filtration that doesn't touch PFAS. The EPA has found that some public drinking water systems have detectable levels of PFAS chemicals.
PFAS testing is expensive and complicated. Many water systems haven't been checked yet. And "detectable levels" doesn't mean "safe levels" — it just means we found them.
Your office might be getting water from one of those contaminated systems. And even if it's not, PFAS can enter water through old pipes, contaminated groundwater, or industrial sources nearby.
The EPA Finally Set Standards
On April 10, 2024 the EPA finalized the first national drinking water standards for PFAS: 4.0 parts per trillion for PFOA and PFOS, 10 ppt each for PFHxS, PFNA and HFPO-DA. Public systems must complete initial monitoring by 2027 and install treatment where levels exceed the limits by 2029. Update, September 2026: in May 2026 EPA proposed letting systems request until 2031 and proposed rescinding the PFHxS, PFNA, GenX and mixture limits; the 4.0 ppt PFOA and PFOS limits stay as written. Final action was still pending when I checked.
That's progress. But it's also years away. And those standards only apply to public water systems — not the private wells or older infrastructure that many offices rely on.
Even after 2029, compliance will take time. Water systems need to install new treatment technology, train operators, and figure out funding. It won't happen overnight.
Your Employees Are Drinking This Every Day
I walk into offices all the time where people are filling up water bottles from the kitchen tap. Or drinking from water coolers that haven't had their filters changed in months. Or using those big 5-gallon jugs that sit in storage rooms getting warm.
OSHA requires employers to provide potable water — 29 CFR 1910.141(b) — and defines potable as meeting the state or local drinking-water standard, or the EPA's National Primary Drinking Water Regulations. So a tap that meets today's municipal standard satisfies OSHA, and that standard's PFAS limits don't bite until 2029 at the earliest. The rule was written around bacteria and basic safety; it doesn't say the words forever chemicals.
The Breakroom Connection to Employee Health
Here's what most companies miss: the CDC's Workplace Health Model treats the physical environment — what's in the breakroom included — as part of a health program, not a facilities line item.
Water quality is part of that equation. Proper hydration affects everything from cognitive function to immune response. And if that water contains PFAS, you're not just failing to help — you might be making things worse.
Most employees spend 8+ hours a day at the office. That's a lot of water consumption from whatever system you've installed.
What Actually Works Against PFAS
A taste-and-odor carbon filter isn't designed for PFAS. The EPA's treatment technologies page names three things that are: granular activated carbon (the most studied, and "100 percent effective for a period of time" depending on the carbon, bed depth and flow), ion exchange resins, and high-pressure membranes like reverse osmosis, which it puts at "typically more than 90 percent effective" including on the short-chain PFAS that carbon struggles with. For a cooler or under-counter unit, the shortcut is a PFOA/PFOS reduction claim under NSF/ANSI 53 or NSF/ANSI 58.
All three work — for a time. The carbon and resin saturate, the membrane fouls, and the system needs regular media changes and monitoring to stay effective.
I see too many offices with RO systems that haven't been serviced in years. The filters are saturated, the membranes are fouled, and they're not removing anything anymore.
The Real Cost of Waiting
Every day you wait is another day your employees are potentially consuming PFAS at work. With most Americans already carrying these chemicals in their blood, the last thing you want is your office adding to the problem.
The EPA's 2029 deadline might feel far away. But PFAS contamination is happening right now. In your employees' bodies. Every single day.
Your office water system is either part of the solution or part of the problem. There's no middle ground with forever chemicals.
If your office is in Wisconsin: I cover the Madison area for Bottleless Nation. I'll test what's coming out of your tap and show you the numbers before you decide anything — see bottleless water coolers in Madison or get in touch.
