TL;DR: This is the first scientific study to compare five different wastewater treatment processes: facultative and aerated lagoons, chemically-enhanced primary treatment, secondary activated sludge, and advanced biological nutrient removal, and determined how their removal is affected by environmental/operational factors in different WWTPs.

TL;DR: This investigation extended the understanding of the occurrence and fate of PPCPs in an MBR process through the analysis of the largest number of compounds in a membrane bioreactor study to date.

TL;DR: Bisphenol-A (BPA) was analyzed in 499 liquid and 347 solid samples collected from twenty-five wastewater treatment plants to investigate parameters affecting BPA occurrence, removal, and fate and showed the best performance in the biological aerated filter and membrane bioreactor processes.

TL;DR: A multimedia comparison of PFAA profiles provided evidence that unexpected patterns in biota of some of the lakes were due to unique source patterns rather than internal lake processes, and the importance of continued monitoring of multiple-media for determining future responses of environmental PFAA concentrations to voluntary and regulatory actions.

TL;DR: PFAAs were formed during wastewater treatment and it was dependant on both process temperature and treatment type; with higher rates of formation in biological wastewater treatment plants (WWTPs) operating at longer hydraulic retention times and higher temperatures.
