What are PFAS?

PFAS, or per- and polyfluoroalkyl substances, refer to a group of human-made chemicals that have been widely used in various industrial and consumer products for their water- and grease-resistant properties. These substances have been utilized in applications such as firefighting foams, non-stick cookware, water-repellent clothing, and food packaging. The relevance of PFAS in the context of water supply stems from their persistence in the environment and their potential to contaminate drinking water sources.

Due to their chemical stability, PFAS do not break down easily in the environment, which raises concerns about their accumulation in ecosystems and potential health effects on humans. Studies have linked certain types of PFAS exposure to various health issues, making their presence in drinking water a significant public health concern.

The other options do not accurately describe PFAS; they either reference biodegradable contaminants, natural minerals, or organic compounds unrelated to water contamination issues. Understanding the implications of PFAS is crucial for water supply management and health safety initiatives.
