“…Passive sampling techniques offer a promising approach for in situ sampling and concentration of PFASs in environmental waters and wastewater. − A microporous polyethylene tube (MPT) passive sampler design has proven effective in detecting target PFASs in surface water , and groundwater . However, the combination of nontarget screening and passive sampling methodologies for PFAS risk assessment remains an unexplored area.…”

Monitoring contamination from per-and polyfluoroalkyl substances (PFASs) in water systems impacted by aqueous film-forming foams (AFFFs) typically addresses a few known PFAS groups. Given the diversity of PFASs present in AFFFs, current analytical approaches do not comprehensively address the range of PFASs present in these systems. A suspect-screening and nontarget analysis (NTA) approach was developed and applied to identify novel PFASs in groundwater samples contaminated from historic AFFF use. A total of 88 PFASs were identified in both passive samplers and grab samples, and these were dominated by sulfonate derivatives and sulfonamide-derived precursors. Several ultrashort-chain (USC) PFASs (≤C 3 ) were detected, 11 reported for the first time in Australian groundwater. Several transformation products were identified, including perfluoroalkane sulfonamides (FASAs) and perfluoroalkane sulfinates (PFASis). Two new PFASs were reported (((perfluorohexyl)sulfonyl)sulfamic acid; m/z 477.9068 and (E)-

“…Passive sampling has emerged as a viable complementary sampling approach for a range of pharmaceuticals and personal care products (PPCPs), illicit drugs, and industrial chemicals in aquatic matrices. − Passive sampling devices (PSDs) are relatively inexpensive due to reduction of costs associated with personnel, equipment maintenance, and a reduced number of samples compared to that potentially required with composite sampling. PSDs concentrate analytes in situ and can have detection limits sufficiently low to enable quantification of trace chemicals not quantifiable in grab samples . They also have the potential to provide continuous time-weighted average (TWA) concentrations that integrate fluctuations or spikes in concentrations .…”

The potential of kinetic passive samplers to monitor per and polyfluoroalkyl substance (PFAS) concentrations in wastewater treatment plants (WWTPs) was evaluated using microporous polyethylene tube (MPT) passive samplers containing hydrophilic−lipophilic-balanced (HLB) or weak-anion-exchange (WAX) sorbents. Sampling rates (R s ) from 28 day deployments in WWTP effluent were consistent with principal resistance to PFAS accumulation in wastewater-filled micropores of the polyethylene tube. Considering both sorbents, PFAS R s in the influent were smaller than in the effluent by a factor of 3.7, attributed to micropore clogging from a colloidal material but not biofilm formation. Combined Isolute ENV+ R s values in the influent and effluent were 2.1 times larger than for Evolute WAX. Exploring their wider applicability, samplers with Sepra ZT-WAX were deployed in six other WWTPs with varying catchment characteristics. R s values were significantly greater than those of Evolute WAX, indicating cationic charge center possession alone is an insufficient criterion for sorbent performance. Based on longer linear uptake timespans (e.g., >10 4 days for PFOA) and provision of timeweighted average concentrations, Evolute WAX was the best sorbent investigated. PFAS concentrations in wastewater derived from MPT samplers gave comparable accuracy to current grab sampling methods (i.e., EPA Method 1633). Findings demonstrate that MPT samplers are useful tools for monitoring PFAS in WWTPs.
