Gluesenkamp Perez, Kim Introduce Bipartisan Legislation to Study Impact of PFAS and Microplastics on Biosolids in Farming

Today, Rep. Marie Gluesenkamp Perez (WA-03) and Rep. Young Kim (CA-40), introduced the bipartisan Research for Healthy Soils Act to research the impact of microplastics and harmful PFAS chemicals on biosolids.

Biosolids are a valuable byproduct of the wastewater treatment process that can be applied to agricultural land to add nutrients to the soil and improve soil structure. Applying biosolids to land saves money for farmers by reducing their need for foreign imports of phosphorus and synthetic fertilizers and keeps waste out of landfills. Biosolids can also serve as an important source of revenue for municipal wastewater utilities, lessening burdens on ratepayers.

While research is limited, studies have shown that biosolids may contain microplastics and PFAS – and it’s important to make sure they aren’t negatively impacting the health of our soil and farmlands.

This bipartisan legislation would authorize the U.S. Department of Agriculture to make grants available to study the incidence and impacts of microplastics and PFAS in biosolids on farmland.

“Our national health benefits from strong local food supply chains, and Southwest Washington farmers benefit from high-quality biosolids from public utilities,” said Rep. Gluesenkamp Perez. “As microplastics and PFAS pose risks to our health and kids’ development, it’s important we build clarity about the full scope of their effects. Our bipartisan legislation will invest in research that will help us better mitigate these chemicals and understand potential impacts to the health of our families and soil.”

“Biosolids have proven to be rich in nutrients and can cut costs for farmers, but we have limited understanding of their impact on soil health, the environment, and public health. Prioritizing biosolids research can help inform and improve our farming methods,” said Rep. Young Kim. “I’m glad to partner with Rep. Gluesenkamp Perez on this commonsense, bipartisan effort.”

In February, Rep. Gluesenkamp Perez introduced bipartisan legislation to shield ratepayers from the costs of PFAS cleanup.
