TL;DR: In this article, the authors discuss the issues surrounding emerging contaminants and also propose some engineering solutions for the future, including widespread occurrence, bioaccumulation, persistence, and toxicity.

TL;DR: Overall, GAC was effective for removing DBP precursors and reducing DBP formation and total organic halogen, even after >22 000 bed volumes of treated water.

TL;DR: A new gas chromatography-mass spectrometry method is developed that simultaneously quantifies 39 priority unregulated DBPs from six different chemical classes and analyzes unknown DBPs with mass accuracy under full-scan conditions, enabling the quantification of 39 DBPs, along with the non-target identification of many other drinking water contaminants.

TL;DR: While calculated genotoxicity decreased in all filters, decreases in overall DBP formation did not correlate with decreases in calculated cytotoxicity, highlighting that DBP concentration alone may not always provide an adequate basis for risk assessment.

TL;DR: Hot shower water from Flint was similar to waters sampled from three other cities and did not have unusually high levels of DBPs or other organic chemicals that could be responsible for the skin rashes observed by residents, although it is possible that an inorganic chemical or microbial contaminant may be responsible.
