The article examines growing environmental concerns surrounding the rapid expansion of artificial intelligence data centers in the United States, particularly in Virginia, where large facilities require significant amounts of water for cooling systems.

Many of these data centers use evaporative or liquid-based cooling methods, which consume and later discharge treated water into municipal wastewater systems or nearby natural waterways.

In some cases, facilities are permitted to release hundreds of thousands of gallons of treated water per day into creeks that eventually feed into larger bodies of water.

While operators, including major tech companies like Amazon, state that the discharged water is treated and regulated according to environmental standards, critics argue that there is insufficient monitoring of chemical contaminants, particularly per- and polyfluoroalkyl substances (PFAS), commonly known as “forever chemicals.” These substances are widely associated with health risks such as cancer, immune system disruption, and reproductive harm.

The article highlights that neither state regulators in Virginia nor the federal Environmental Protection Agency currently require routine PFAS testing for data center wastewater discharges, creating what experts describe as a major knowledge gap.

Environmental advocates warn that chemicals used in cooling and treatment processes could still pose risks despite compliance with existing permits that primarily regulate metals, chlorine, temperature, and pH levels.

Meanwhile, the federal government has prioritized the expansion of AI infrastructure, including data centers and supporting energy systems, while the EPA is reportedly fast-tracking chemical approvals for industry use.Ongoing legislative efforts in Virginia aim to expand PFAS testing requirements, but data centers are not yet fully included under existing laws.

A public hearing on a proposed Amazon facility permit underscores continued debate over balancing technological growth with environmental and public health protections.
