Is the AI Revolution Powering a New "Tidal Wave" of PFAS?
Artificial intelligence is seemingly everywhere. We’ve written recently about how it’s transforming industries like medicine (check out our post, Healthcare AI: The good, the bad, and the uncanny). But behind the magic of generative AI and lightning-fast computing, there is a massive, hidden environmental cost that is just beginning to make headlines. The AI boom is triggering an explosion in the production of "forever chemicals."
According to a sobering new report recently highlighted in The Guardian, the world's leading chemical manufacturers are preparing a "tidal wave" of PFAS production to meet the massive demands of the AI industry.
If you've been reading the Relentless Health blog for a while, you know the dangers of per- and polyfluoroalkyl substances (PFAS). But how did our computing demands get so tangled up with toxic chemicals? And more importantly, what can we do about it?
Why Does AI Need "Forever Chemicals"?
The insatiable demand for AI comes down to two heavily PFAS-reliant processes: making AI chips and cooling them down.
First, semiconductor manufacturing is an extremely complex process that involves 500+ highly specialized chemicals. Among these chemicals, PFAS are a key component and are integrated into as many as 1,000 distinct steps at the nanometric level of chip fabrication.
Second, AI requires massive server farms that run incredibly hot. To keep them from overheating, many facilities are turning to "two-phase immersion cooling." While it sounds like a clean, high-tech solution, it actually involves submerging server hardware directly into giant vats of boiling PFAS fluids to draw the heat away. In this use case, PFAS is the primary fluid, where it vaporizes near hot components and condenses on a cooling coil to remove heat. Their chemical stability, heat-transfer properties, and low flammability make them effective, but their extreme persistence creates environmental, disposal, and regulatory concerns. The fluid is not destroyed during the cooling cycle, so containment and recovery are important. PFAS may also occur in seals, hoses, and coatings, meaning PFAS-free cooling requires checking the entire system, not just the primary coolant. When surveyed by the Swedish chemicals watchdog ChemSec, nearly all of the top 10 largest PFAS manufacturers confirmed they are ramping up production (and opening new facilities), specifically to serve the AI and datacenter boom.
A Hidden Cost of the Tech Boom
PFAS are notorious for their unbreakable carbon-fluorine bonds. They do not degrade in nature, meaning every drop manufactured will eventually cycle through our soil, air, and waterways.
As we've covered in past articles, these chemicals accelerate biological aging, disrupt hormones, and are linked to liver disease, high cholesterol, and cancer. Because of decades of industrial use, forever chemicals have already breached planetary boundaries and can be found in the blood of more than 99% of people worldwide. A massive uptick in production to feed our datacenters threatens to make a bad public health crisis even worse.
It’s Not All Doom and Gloom
It is easy to read these reports and feel helpless, but the future of technology does not have to be coated in toxic chemicals. There are highly viable solutions emerging on both an industrial and a personal level.
On the Industry Side:
- Datacenters don't actually need PFAS to stay cool. The industry is already seeing a pivot toward alternatives like "single-phase direct-to-chip liquid cooling." This method uses a simple, non-toxic mix of 75% water and 25% glycol, proving that we can cool AI datacenters without poisoning the planet.
- Not every chemical company is doubling down on PFAS. Major players like the German giant BASF have pledged a complete exit from PFAS production by 2028, and others like Archroma are actively pivoting exclusively to PFAS-free alternatives.
- As awareness grows, investors and regulators are beginning to view PFAS as the "hidden risk" of the AI boom, warning of multibillion-dollar liabilities. Financial pressure is one of the fastest ways to force greener innovation.
On the Personal Side (What You Can Do):
While we wait for regulations to catch up with the tech boom, you can take proactive steps to protect your own health right now.
- Filter Your Tap Water. Increased industrial production inevitably leads to water contamination, so ensuring your home has a high-quality water filter certified to remove PFAS is your best first line of defense.
- Measure your PFAS levels. You can't fix what you don't measure. Using our Relentless Health PFAS Core Panel, you can get an accurate baseline of the forever chemicals currently in your blood.
- Support Natural Clearance of PFAS. You don't have to just live with your exposure. The human body can process these chemicals out over time, and you can support that process. Look into our PFAS management program in partnership with Cambiotics, offering specialized probiotics designed to support the natural clearance of PFAS from your system.
AI has the potential to solve some of the world's most complex problems. But we must demand that the infrastructure powering it doesn't compromise our health in the process. Progress shouldn't come at the cost of our health.
