This publication assists industry to identify non-point source concentrations of PFAS in the environment. The document disseminates data gathered by EPA. This includes concentrations of PFAS in:

• freshwater
• sediment
• riparian soil (i.e. soil samples collected next to freshwaters).

PFAS concentrations are provided for different land use settings (e.g. agricultural, urban, mixed land use). The concentrations relate to PFAS migration from non-point sources to receiving waterways. The data presented is of relevance to ecological and human receptors that may be exposed to PFAS in these waterway settings.

This document is not a guidance document. It is a science report that summarises state of knowledge on PFAS in the ambient environment.
