This joint resolution from the Montana Legislature requests an interim study focused on endocrine-disrupting chemicals, specifically including perfluoroalkyl and polyfluoroalkyl substances (PFAS), and their impact on water quality. The resolution highlights concerns regarding the declining human reproduction rates globally, attributing this decline to unhealthy lifestyles and environmental chemicals. It emphasizes the health risks associated with endocrine-disrupting chemicals, which are prevalent in various consumer products and may contribute to numerous health issues in both men and women. The resolution calls for a comprehensive examination of existing state and federal water quality laws, the presence of PFAS in Montana, and the potential health effects of these chemicals.

The study aims to review current regulations, analyze the prevalence of endocrine-disrupting chemicals, and provide recommendations for future actions regarding water quality and chemical regulation. The findings from this study are to be presented to an appropriate committee and reported to the 70th Legislature by September 15, 2026. This initiative represents a proactive step by the Montana Legislature to address potential public health risks associated with these chemicals in drinking water and to explore solutions for mitigating their impact on human health and the environment.
