PFAS Potential Exposure from Biosolids
- Direct exposure (minimal risk)
- Indirect exposure-drinking water-plant/animal uptake
- Bioaccumulation
SPECIFIC OBJECTIVES
- At land application sites nationwide, measure:
- Incidence of PFAS in soil following long-term land application of biosolids and at various soil depths
- Assess Mobility (leaching) of PFAS analytes through soil and vadose zone
- Evaluate PFAS in groundwater to create paired data sets of soil and water PFAS concentrations
- Crop uptake of PFAS analytes, utilizing paired data sets of soil PFAS concentrations versus plant uptake
