State PFAS Legislation: Here’s the Score at Halftime

Earlier this year, I did an analysis of the PFAS-related bills proposed at the state level in 2025. I wanted to see if the legislative focus had changed, e.g., less attention paid to drinking water and more to other matrices such as biosolids. That post was written early enough into the new year that most bills had been proposed, but none had successfully made it through the process yet. In this post, we’ll provide a snapshot of which bills have made it through their respective state legislatures to be enacted into law.  

When reviewing the numbers, keep in mind that as of June 30, most state legislatures have adjourned for the year. Only eight will continue into the second half of 2025: California, Massachusetts, Michigan, New Jersey, Ohio, Pennsylvania, and Wisconsin. Of course, these are heavily industrialized states, so we may see more PFAS-related bills passed before their sessions end. In addition, although already adjourned, some states may have passed legislation that is simply waiting for a signature. As I write this post, this is the case with Delaware S.B. 72 and Illinois H.B. 2516 in the table below, but there may be others I did not catch. 

PFAS Bills Passed in First Half of 2025 

Let’s start with the PFAS legislation passed by states during the first half of the year. I’ve left off appropriations bills in the list below as they are often focused on funding already-enacted legislation. 

Here’s the Halftime Score 

Of the 200 bills introduced in 2025, only 18 have been enacted so far. This count includes appropriations bills, studies, reporting requirements, and other non-limit setting legislation. I’ve also added the Delaware bill in the chart above that has been sent to the governor for signature. Although there is always the possibility of a veto, my gut tells me it’s unlikely. 

The seven state legislatures that are still in session have 39 PFAS-related bills outstanding. There is probably some overlap between the 39 outstanding bills, so this will naturally be narrowed down through consolidation. However, in 2024, states enacted 20 PFAS-related bills, so we could easily see more PFAS-related legislation enacted at the state level this year than last year. Whether it will match the PFAS legislation high-water mark set in 2022 remains to be seen. 

Finally, as we consider the numbers, it’s also important to keep in mind that not all PFAS rulemaking is done in the state legislature. Many states enact legislation giving state agencies the authority (and sometimes a mandate) to enact rulemaking as the agency sees fit. For example, Washington State granted its Department of the Ecology broad power to determine which categories of consumer products would be included in the state ban on intentionally added PFAS under its Safer Products rule. 

How Can We Help? 

At Pace®, our purpose is not to promote specific pieces of legislation. Rather, it is to help our clients remain in compliance by providing testing services for environmental contaminants across a wide array of regulated matrices, such as drinking water, wastewater, ground and surface water, biosolids, landfill leachate, biota, etc. We’re also happy to answer questions about the science of PFAS testing, removal, and remediation as you create and assess your compliance strategy. Request a quote or reach out to us at any time! 

As always, I want to thank Safer States for the work they do tracking legislation at the state level. While we keep an independent eye on what’s happening in key states, being able to tap into their database and filter results has saved us countless hours of effort researching and consolidating information from state legislative sites, some of which are better than others.
