SB 5033 proposes changes to the biosolids management program, including testing for PFAS chemicals in municipal sewer sludge.
The bill, sponsored by Sen. Jeff Wilson (R–Longview), requires the Washington Department of Ecology to establish PFAS chemical sampling and testing requirements of biosolids by July 2027. The goal of the sampling is to complete an analysis of the level of PFAS found in municipal biosolids by July 2028, with a report to the Legislature due in December of that year with “recommendations on how to proceed based on that analysis.”
The biosolids management program regulates the use and disposal options for municipal sewer sludge. It is widely known that PFAS—known as forever chemicals because of their ability to bioaccumulate and not breakdown—are found in 98% of Americans, occur before we are born and compound in our bodies throughout our lives. PFAS is ubiquitous in the environment and is used on thousands of consumer products still produced today, many of which are washed in our sinks and washing machines, going into the city sewer system. PFAS is in the air and water and is even on Mount Everest.
Municipal wastewater treatment plants are passive receivers of what is in humans, businesses, and the environment. Will it be in biosolids? Yes. At what level is unclear. The question is who will bear the cost to test and treat? AWC supports proposals that develop science-based policies and environmental regulations that deliver meaningful benefits to both human health and the environment.
The U.S. Environmental Protection Agency convened stakeholders in 2023-2024 to discuss the issue and its significant challenges. The report was just released.
