Datacenters Face Scrutiny Over 'Forever Chemical' Pollution Amid AI Boom

Datacenters Face Scrutiny Over 'Forever Chemical' Pollution Amid AI Boom

The rapid growth of AI is fueling a surge in datacenters, raising alarms among health advocates and regulators about pollution from PFAS, or "forever chemicals," used in critical cooling systems.

AI Boom Sparks Environmental Concerns

The global AI boom, led by tech giants like Google, Microsoft, and Amazon, is fueling an unprecedented expansion of datacenters. But this growth is casting a new shadow on their environmental impact, as advocates and regulators raise alarms over the use of PFAS "forever chemicals" in cooling systems.

These massive facilities, critical for powering AI and cloud computing, require constant cooling to prevent servers from overheating. Many rely on refrigerant gases, known as f-gases, that contain per- and polyfluoroalkyl substances (PFAS)—a group of about 16,000 synthetic chemicals known for their extreme persistence in the environment.

Regulatory Scrutiny Begins

The issue has gained significant attention, prompting the U.S. Environmental Protection Agency (EPA) to act. In September 2025, the agency announced it would begin tracking and prioritizing reviews of PFAS use in data centers, acknowledging a lack of sufficient data on their long-term effects.

According to a report from Inside Climate News, health advocates argue that this area has been "dangerously understudied," posing potential risks to workers, supply chains, and communities near these sprawling facilities.

Dual Threat to Health and Climate

PFAS pollution represents a twofold problem, compounding existing concerns over the tech industry's massive energy and water consumption. The chemicals are linked to serious health conditions, and their emissions contribute directly to climate change.

Public Health Risks

PFAS are called "forever chemicals" because they do not break down naturally, accumulating in water, soil, and living organisms. As highlighted by The Guardian, exposure is associated with a range of health problems:

  • Cancer

  • Birth defects

  • Kidney disease

  • Decreased immunity

Localized pollution can occur through leaks, emissions during manufacturing, or improper disposal of cooling equipment, potentially contaminating the air and water supplies of nearby communities.

A Growing Climate Concern

Beyond direct health impacts, some PFAS used as coolants are potent greenhouse gases. Their release into the atmosphere exacerbates the climate footprint of data centers, which are already major energy consumers.

An analysis from MIT forecasts that the electricity demand from AI data centers alone could more than double by 2030. With most of that energy still sourced from fossil fuels, the industry's carbon emissions are on a dangerous trajectory.

Industry Response and the Search for Alternatives

As regulatory and public pressure mounts, the tech industry is beginning to explore solutions to mitigate its environmental impact. The focus is shifting toward developing and implementing alternative cooling technologies that do not rely on harmful chemicals.

Innovations in Cooling

Microsoft has been a vocal proponent of change, with its research in the journal Nature highlighting the need for a full "life cycle assessment" of datacenter operations. The company is actively exploring newer methods such as:

  • Cold plates: A form of direct liquid cooling that is more efficient and reduces the need for traditional refrigerants.

  • Immersion cooling: Submerging servers in non-conductive fluids to manage heat, which can dramatically lower energy use and emissions.

Resource Strain in Datacenter Hubs

The need for sustainable solutions is especially urgent in regions with a high concentration of data centers, like Northern Virginia. These areas already face significant strains on their electricity grids and water resources. The added threat of PFAS contamination puts further pressure on local infrastructure and ecosystems, making the transition to safer, greener technologies a critical priority.

How do PFAS chemicals impact human health?

Exposure to PFAS, known as "forever chemicals," is linked to severe health issues, including an increased risk of cancer, kidney disease, birth defects, and compromised immune system function. These substances can accumulate in the body and the environment over time.
