PFAS: Understanding the Threat to Water Quality

What Are PFAS?

Per- and polyfluoroalkyl substances (PFAS) are a group of human-made chemicals used in a wide range of products for their resistance to heat, water, and oil. These “forever chemicals” do not break down easily in the environment or in our bodies, leading to widespread contamination concerns.

PFAS have been used in everything from nonstick cookware and water-repellent clothing to firefighting foams and cosmetics. Unfortunately, their persistence means they can accumulate in soil, water, wildlife, and people, raising serious health and environmental questions.

PFAS and the Environment

Once released, PFAS can travel long distances through air and water. They have been detected in surface water and groundwater all around the world — from the deepest reaches of the ocean to both of Earth’s poles. Commonly called forever chemicals, PFAS are difficult to break down and last a long time in the environment.

Our PFAS Research

At Stroud Water Research Center, we are committed to understanding how PFAS impact freshwater systems, especially through agricultural and municipal practices that may unknowingly contribute to contamination. Our research focuses on how PFAS enter soils and surface waters, how long they persist, and what we can do to mitigate the risks.

Our Commitment

Stroud Water Research Center is committed to advancing scientific understanding and promoting best practices to safeguard water quality. As awareness of PFAS grows, so too does our focus on helping communities, farmers, and policymakers make informed decisions grounded in science.
