Modeling the transport of sucralose, an anthropogenic tracer, in an effluent dependent watershed with the Soil and Water Assessment Tool during an extreme drought.
Contaminants of emerging concern (CECs) in rapidly urbanizing watersheds represent an area of increasing attention. The Soil and Water Assessment Tool (SWAT), has been used for numerous water quality and quantity assessments, but CEC studies using SWAT are limited. Because the North Bosque …

Evaluating non-point source microplastic pollution and its impact on biota in the Huron River
<p>Contaminants of emerging concern (CECs), like microplastics and pharmaceuticals, are a growing threat to aquatic ecosystems across the globe. Microplastics can be transported into waterways through a myriad of sources, including point sources such as wastewater treatment plants (WWTPs) and …

Evaluation of Contaminant Removal Through Soil Aquifer Treatment by a Lab Scale Soil Column Experiment Including a Trace Contaminant Spike Test
Soil aquifer treatment (SAT), the removal of contaminants during percolation through soil, is a strategy employed in managed aquifer recharge (MAR), one method of indirect potable water reuse. As part of Hampton Roads Sanitation District's (HRSD) MAR project, The Sustainable Water Initiative for …

CHARACTERIZATION OF SEPTIC SYSTEM WASTEWATER AND MUNICIPAL SOLID WASTE LANDFILL LEACHATE
… a corresponding increase in the use and release of contaminants of emerging concern (CECs). The increasing volume and changing composition of waste poses new challenges for waste management and the protection of ecosystem, surface water, and groundwater resources. In the U.S., most domestic solid …

Nanofiltration Rejection of Contaminants of Emerging Concern from Municipal Water Resource Recovery Facility Secondary Effluents for Potable Reuse Applications
<p>As reuse of municipal water resource recovery facility (WRRF) effluent becomes vital to augment diminishing fresh drinking water resources, concern exists that conventional barriers may prove deficient and the upcycling of contaminants of emerging concern (CECs) could prove harmful to human …

Treatability of emerging contaminants in wastewater treatment plants during wet weather flows
… (PPCPs), also enter the wastewater stream. Some of these nontraditional contaminants are not efficiently removed by the treatment process at the wastewater treatment plant. Emerging contaminants (ECs) have been identified in surface waters receiving wastewater effluents and have been found to …

Sorption and bioaccumulation of neutral and ionizable wastewater-derived contaminants of emerging concern: exposure of edible crops via solid and liquid effluent streams
Diverse contaminants of emerging concern (CECs) are ubiquitous in waste streams. Batch sorption tests with sludge solids from wastewater treatment systems examined sorption to the solid phase of CECs during wastewater treatment. Compounds, including neutral, acidic and basic CECs, were evaluated …

Investigation of Bromate Formation during Ozone-Biofiltration Treatment Processes for Potable Reuse Application
… regions. Consequently, as an essential component of water resource management, potable reuse of municipal wastewater has been taken into consideration. Potable reuse projects mainly employ multiple purification steps to provide effective inactivation of pathogens as well as organic and inorganic …

Profiling of Microbial Communities, Antibiotic Resistance, Functional Genes, and Biodegradable Dissolved Organic Carbon in a Carbon-Based Potable Water Reuse System
… on conventional freshwater resources in the face of population growth, sea level rise, source water depletion, eutrophication of water bodies, and climate change. Potable water reuse intentionally looks to purify wastewater effluent to drinking water quality or better through the development and …

Evaluating the Occurrence, Fate and Human Health Risks of Contaminants of Emerging Concern in the Atlantis Managed Aquifer Recharge Scheme
… in water-scarce regions. However, the quality of these recharge waters is a concern, as they often contain contaminants of emerging concern (CECs) that may persist in groundwater and pose risks to human health if left untreated. This study aims to evaluate the impact of MAR on groundwater …

Use of Biochar to Produce Reclaimed Water for Irrigation Reuse Purposes
Contaminants of emerging concern (CECs), especially, pharmaceutical and personal care products (PPCPs) are not removed well during conventional wastewater treatment and hence pose water quality risk to the environment and potentially to public health. The goal of this work was to remove CECs, with …

Ricerca delle fonti di contaminazione in acquedotti e fognatura: definizione di un approccio integrato
Negli ultimi anni la qualità delle acque potabili e reflue ha suscitato crescente preoccupazione a causa della diffusione di contaminanti di interesse emergente (es. PFAS, farmaci) e dei loro impatti ambientali. In questo contesto, la tesi presenta un approccio integrato per il monitoraggio …
