Please note the corrigendum published by Wiley’s Remediation Journal:

“In Volume 30, in the article, “Six Pilot-Scale Studies Evaluating the In Situ Treatment of PFAS in Groundwater” by Rick McGregor the following changes were made

1. In the abstract the units for the concentration of various PFAS compounds were reported as ug/L, they should be ng/L and read:  “24,000 ng/L perfluoropentanoic acid (PFPeA), up to 6,200 ng/L pentafluorobenzoic acid (PFBA), 16,100 ng/L perfluorohexanoic acid (PFHxA), up to 6,080 ng/L perfluoroheptanoic acid (PFHpA), up to 450 ng/L perfluorooctanoic acid (PFOA) and up to 140 ng/L perfluorononanoic acid (PFNA)”
2. In the abstract pentafluorobenzoic acid should be read “perfluorobutanoic acid”
3. On page 41 pentafluorobenzoic acid should be changed to “per-fluorobutanoic acid”.

These errors were introduced during the writing process and do not affect any of the results presented.”

Background

This article published in Wiley’s Remediation Journal is written by Rick McGregor of IRSL and reviews 6 pilot-scale in situ field studies of an unconfined sand aquifer impacted by both petroleum hydrocarbons and PFAS to determine if a variety of reagents could be used to attenuate the dissolved PFAS. The reagents were injected using direct push technology, consisted of 2 chemical oxidants, and 4 adsorbents. Performance results 18-months post application are provided.
