NGWA taking public comments on PFAS guidance document

June 5, 2017  By Ground Water Canada

Westerville, OH – The National Ground Water Association is now accepting public comments on the guidance document titled “Groundwater and PFAS: State of Knowledge and Practice” until July 31.

“Groundwater and PFAS: State of Knowledge and Practice” was developed to identify the known science and knowledge related to perfluoroalkylated substance, or PFAS, compounds present in ground water. It also considers the subsurface and the current state of the art in practices relating to the ecological impacts, as well as the human uses of ground water, the NGWA said in a news release.

The document also identifies gaps in knowledge, or information that is currently in a state of flux in terms of scientific consensus. This document is a collaborative effort, created and edited by volunteer ground water professionals, and is 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, the organization said.


The intent of Groundwater and PFAS: State of Knowledge and Practice is to provide technically defensible guidance useful in defining an appropriate path forward for a client, a water resource, or a regulatory action, using a series of concise, but technically defensible, documents – each highly focused on a number of appropriate categories useful to consulting ground water scientists and engineers, drinking water system operators utilizing ground water suppliers, and ground water regulatory personnel at all levels of government.

This document is provided for informational purposes only, the NGWA said. Members and others using this publication are free to adopt other standards and approaches as they see fit based on an independent analysis of such factors.

The NGWA does not purport to have conducted a definitive analysis on the topic described in this publication, and it assumes no duty, liability, or responsibility for the contents or use of the publication.

All comment submissions are to be made online at and will be accepted through July 31, 2017. All revisions to the existing drafts will be made at the discretion of the appropriate subtask group.

You may email any comments or questions on the document drafting procedure to the staff facilitator of this project, Kevin McCray, CAE, at
