| Description | In 2024, the Washington Department of Ecology carried out a study to assess PFAS concentrations in biosolids generated at 44 WWTPs across Washington state. There are approximately 375 WWTPs across the state. Participating facilities varied in size, location, and types of residential and industrial inputs they receive. The goals of the study were to (1) begin collecting data on the levels of PFAS concentrations in Washington biosolids, and (2) gain a better understanding of the sampling process for U.S. Environmental Protection Agency Method 1633. This study will strengthen the technical assistance Ecology staff provides to WWTPs in the future. |
