On June 18, 2026, the California Department of Toxic Substances Control (DTSC) added microplastics to the list of Candidate Chemicals maintained under the state’s Safer Consumer Products (SCP) regulations.  The listing of microplastics, which becomes effective on October 1, 2026, is the first step in the SCP regulatory process, which could lead to restrictions on products that contain or release microplastics. 

On July 1, 2026, EPA proposed the sixth Unregulated Contaminant Monitoring Rule (UCMR 6), which will require public water systems (PWS) to monitor 30 unregulated contaminants — including certain PFAS chemicals — but not microplastics.
