Fate of Per- and Polyfluoroalkyl Ether Acids in the Total Oxidizable Precursor Assay and Implications for the Analysis of Impacted Water
Environmental Science & Technology Letters, 6(11), 662–668.
TL;DR:
Application of the total oxidizable precursor (TOP) assay in its proposed enhanced form revealed high levels of PFEAs, the presence of precursors that form perfluoroalkyl carboxylic acids, and the absence of precursor that form P FEAs in surface water impacted by PFAS-containing wastewater discharges.

TL;DR:
A comparison of adsorption isotherm data collected in the presence and absence of NOM showed that percent reductions of single-solute TCE and MTBE adsorptive capacities that resulted from the presence of co-adsorbing NOM were not strongly affected by the chemical characteristics of activated carbons.
