| Description |
The Department of Ecology oversees a biosolids management program where solids from wastewater treatment plants (WWTPs) and domestic septic systems are required to be beneficially used on the land for their nutrient and soil amending values. WWTP solids that meet the standards are considered “biosolids” and are agronomically land applied to farmland as a fertilizer and a soil amendment. There is evidence from sample results in Washington and other states that biosolids have PFAS. Washington has little data on PFAS in biosolids produced at WWTP’s, but since PFAS use is pervasive it is likely that PFAS will be detected in biosolids generated in Washington. To gather more data, Ecology will conduct sampling of biosolids from several WWTPs. |
