Evaluation of stormwater control measures for the removal and fate of legacy and emerging contaminants
… and human health due to the strong affinity many contaminants have for sediments. While efforts to control point sources have reduced pollutant inputs, nonpoint sources such as stormwater runoff continue to transport contaminants and contaminated sediments into receiving waters. Stormwater control …

Degradation of Emerging Contaminants by Advanced Oxidation Using Multi-Walled Carbon Nanotubes and Continuous Ozone Injection
… wastewater treatment facilities to eliminate emerging contaminants from our water systems. AOPs increase the generation of hydroxyl radicals (•OH) in oxidation reactions, which are less selective and more reactive than other oxidants, such as ozone, so they are more effective at degrading …
-
Prediction of the Degradation of Emerging Contaminants During Oxidative Treatment via Analysis of Reaction Rate Constants
… been paying increased attention to unregulated emerging organic contaminants. Advanced oxidation processes (AOPs), which produce hydroxyl radicles (•OH), have been developed and implemented to remove recalcitrant emerging contaminants left by conventional treatment processes. The current …

Emerging Contaminants: Occurrence of ECs in Two Virginia Counties Private Well Water Supplies and Their Removal from Secondary Wastewater Effluent
Emerging contaminants (ECs) are chemicals such as pharmaceuticals and personal care products that have been detected in various environmental matrices, including drinking water supplies at trace concentrations (ng/L-ug/L or ng/kg-ug/kg). Current wastewater treatment plant technology is largely …
-
Effect of wastewater colloids on membrane removal of microconstituent antibiotic resistance genes
… resistance genes (ARGs) are considered emerging contaminants, as they are associated with a critical human health challenge, are persist independent of a bacterial host, are subject to transfer between bacteria, and are present at amplified levels in human-impacted environments. Given …
