The purpose of Groundwater and PFAS: State of Knowledge and Practice is to identify for the defined audiences the known science and knowledge related to PFAS compounds present in groundwater and the subsurface, as well as the current state of the art in practices relating to the ecological impacts, as well as the anthropogenic uses of groundwater. The document will also identify gaps in knowledge, or information that is currently in a state of flux in terms of scientific consensus.
The intention is to provide technically defensible guidance useful in defining an appropriate path forward for a client, a water resource, or a regulatory action.
This purpose shall be met by a series of concise, but technically defensible, documents — each highly focused on a number of appropriate categories useful to the defined audiences.
The audiences for this collection of works relevant to groundwater impacted by PFAS are consulting groundwater scientists and engineers, drinking water system operators utilizing groundwater suppliers, and groundwater regulatory personnel at all levels of government.
The drafts below were created and edited by volunteer groundwater professionals and are based upon assessment and interpretation of available literature providing informed perspectives and/or best-in-class solutions from a variety of sources, both internal and external to NGWA.
NGWA is now accepting public comments on the drafts below (click to download PDF of each draft document).
