Michigan 2025-2026 Regular Session

Michigan House Bill HB4768

Introduced
8/13/25  

Caption

Water supply: quality and standards; testing and reporting of the amount of microplastics in public drinking water supplies; require. Amends sec. 5 of 1976 PA 399 (MCL 325.1005) & adds sec. 6a.

Impact

The bill's implementation would significantly influence existing state laws regarding water quality and safety. By requiring the testing and reporting of microplastics in public water supplies, HB4768 aims to ensure better protection of public health. Additionally, it directs the Department to consider various water sources, including those near agricultural operations and landfills, which aligns with current efforts to mitigate environmental contamination in vulnerable populations. The quarterly assessments are intended to address both regulatory compliance and public health concerns, especially in communities reliant on the affected water sources.

Summary

House Bill 4768 seeks to amend the Safe Drinking Water Act of Michigan by introducing specific regulations and methodologies for the monitoring and reporting of microplastics in public drinking water supplies. The proposed amendments include the establishment of a microplastics program that will support the assessment of the presence and effects of microplastics in water sources. This program mandates that the Michigan Department of Health and Human Services conducts quarterly monitoring and testing from July 1, 2027, to July 1, 2030. It aims to identify baseline conditions and potential sources of microplastics in drinking water, thereby enhancing overall water quality management practices.

Contention

Despite the potential benefits, there are points of contention surrounding the bill. Critics may argue that the requirements may impose additional burdens on public water systems while also raising concerns about the state's capacity to enforce these new regulations adequately. Stakeholders from multiple sectors may debate the costs associated with implementing the proposed monitoring program and the implications for water utilities, which may struggle to meet these new standards without additional funding or resources. Furthermore, discussions about the toxicological impact of microplastics and how they should be regulated within public health frameworks could arise, reflecting broader conversations about environmental justice and community health outcomes.
