1. Quantifying photo-production of triplet excited states and singlet oxygen from effluent organic matter

Author:
O'Connor, Meghan; Helal, Samantha R.; Latch, Douglas E.; Arnold, William A.

Water research 2019 v.156 pp. 23-33
ISSN:
0043-1354
Subject:
absorption; effluents; energy; hydrochemistry; molecular weight; organic matter; rivers; singlet oxygen; wastewater; wastewater treatment; Arizona; California; Minnesota
Abstract:
... The organic matter present in wastewater effluents (EfOM), is likely to have different properties than the organic matter present in the receiving water. The properties of EfOM will affect the fate of contaminants of emerging concern because EfOM is a source of photochemically produced reactive intermediates (PPRIs) capable of transforming contaminants. Effluent water samples were taken seasonally ...

Abstract:
... Comprehensive monitoring of water pollution is challenging. With the increasing amount and types of anthropogenic compounds being released into water, there are rising concerns of undetected toxicity. This is especially true for municipal wastewater effluents that are discharged to surface waters. This study was designed to integrate zebrafish toxicogenomics, targeted gene expression, and morpholo ...

6. Seasonal variation in accurate identification of Escherichia coli within a constructed wetland receiving tertiary-treated municipal effluent

Subject:
seasonal variation; constructed wetlands; wastewater treatment; effluents; Escherichia coli; microbial contamination; pathogen identification; water quality; environmental monitoring; coliform bacteria; feces; wildlife; electrical conductivity; hydrochemistry; microbiology; Arizona
Abstract:
... As the reuse of municipal wastewater escalates worldwide as a means to extend increasingly limited water supplies, accurate monitoring of water quality parameters, including Escherichia coli (E. coli), increases in importance. Chromogenic media are often used for detection of E. coli in environmental samples, but the presence of unique levels of organic and inorganic compounds alters reclaimed wat ...

Abstract:
... A "what-if" scenario where biological agents are accidentally or deliberately introduced into a water system was generated, and artificial neural network (ANN) models were applied to identify the pathogenic release location to isolate the contaminated area and minimize its hazards. The spatiotemporal distribution of Escherichia coli 15597 along the water system was employed to locate pollutants by ...
