SUMMARY:PFAS: Some Basics (webinar)
DESCRIPTION:Note: This webinar is presented for informational purposes. The views expressed do not necessarily reflect those of each of the NEWMOA-member states\, and the strategies and technologies discussed should not be considered an endorsement by NEWMOA or its members. \nLinda Gaines\, US EPA presented Historical Uses of PFAS [PDF]. The presentation showed Linda’s extensive research and divides the uses known to have led to environmental contamination from those not confirmed as known sources. \nIan Ross\, CDM Smith presented Broad Spectrum PFAS – Detecting Precursors [PDF]. Ian discussed how to understand per versus poly fluoroalkyl substances\, the influence of manufacturing method\, precursor transformation\, and the importance of getting the full picture. Analytical methods and examples were discussed. \n \nFor more information\, contact Jennifer Griffith at jgriffith@newmoa.org.

SUMMARY:PFAS: Two Emerging Issues (webinar)
DESCRIPTION:Note: This webinar is presented for informational purposes. The views expressed do not necessarily reflect those of each of the NEWMOA-member states\, and the strategies and technologies discussed should not be considered an endorsement by NEWMOA or its members. \nIan Ross\, CDM Smith presented Ultrashort PFAS – the Long and Short of It! [PDF] Ian focused on ultrashort PFAS (C1-C3) and discussed their fate & transport and their precursors; chemical analysis; anthropogenic background; how refrigerant use leads to ultrashort PFAS in rain; safer alternatives; and toxicology and exposure. \nLaura Trozzolo\, TRC presented PFAS Practical Guide to Vapor Intrusion [PDF]. Laura will discuss: Exposure and Toxicity Updates; PFAS in Indoor Air;  and Recent PFAS Occupational Studies. \n \nFor more information\, contact Jennifer Griffith at jgriffith@newmoa.org.

SUMMARY:PFAS Forensics: Best Practices for Unwinding Complex PFAS Sources (webinar)
DESCRIPTION:Note: This webinar is presented for informational purposes. The views expressed do not necessarily reflect those of each of the NEWMOA-member states\, and the strategies and technologies discussed should not be considered an endorsement by NEWMOA or its members. \nMichael Eberle\, TRC presented Whose PFAS is it? Tips for Forensic Evaluations [PDF]. Evaluation of the relative composition of individual PFAS compounds in surface water and groundwater samples can be an effective method to identify the source(s) of PFAS in these media.  Comparison of chemical fingerprints in samples collected from surface water bodies and groundwater located downstream and downgradient of contaminated sites may appear to be the same simply because of the suite of analytes chosen for fingerprinting but fate and transport mechanisms (e.g.\, commingling\, persistence\, sorption\, dilution) must be considered during source identification.  PFAS fate and transport properties\, including precursor transformation and sorption of PFAS to solids was examined in regard to the resulting fingerprints. \nMatthew Dunn\, TetraTech presented Precursor PFAS: A New Fluorinated Feedback Loop [PDF]. Matt focused on methods and approaches that can help improve the efficacy of forensic approaches\, including how the use of time weighted average data from passive samplers provides a broader and more representative set of data for forensics. Use of fate and transport models to understand pathways\, distances\, and fates of chemicals was discussed\, and the importance of environmental meta data. Lastly\, examples from published research displayed how environmental processes on small and large scales can impact source attribution studies. \n \nFor more information\, contact Jennifer Griffith at jgriffith@newmoa.org.
