Natural water sources are frequently contaminated by pernicious anthropogenic practises and municipal wastewater discharges containing xenobiotic pollutants and their sometimes more toxic degradation products, or both. Although wastewater is regarded as both a resource and a problem, as explained in this review, it is troubling that, while the global village is still grappling with determining the mode of proper handling, subsequent discharge, and regulation of already established aromatic contaminants in wastewater, some more aggressive, stealthy, and sinister groups of compounds emerge. It is ironic that the majority of these compounds are 'go-to' consumables in our current society and have been suspected of posing a number of health risks to the aquatic ecosystem.
