This joint resolution from the Montana Legislature calls for an interim study on endocrine-disrupting chemicals, specifically focusing on perfluoroalkyl and polyfluoroalkyl substances (PFAS), and their impact on water quality. The resolution highlights concerns regarding declining human reproduction rates and the potential health risks associated with exposure to these chemicals, which are prevalent in various consumer products and the environment. The study aims to review existing state and federal water quality laws, analyze the presence and sources of PFAS in Montana, and assess the health effects of endocrine-disrupting chemicals.

The resolution mandates that the findings and recommendations from the study be presented to an appropriate committee and reported to the 70th Legislature by September 15, 2026. It emphasizes the need for a comprehensive understanding of how these chemicals affect both human health and the environment, with the goal of exploring potential solutions to mitigate their risks.
