QMRA for assessing treatment needs of surface water for drinking: trends and challenges in fecal pathogen quantification

Pathogens are widespread in surface waters, necessitating effective microbial removal by drinking water treatment systems to ensure public health. Quantitative microbial risk assessment (QMRA) provides a robust framework to estimate required pathogen ...

Evaluating Microbial Health Risks Associated with Direct Potable Water Reuse

Pollutants
Water scarcity is driving increasing interest in potable water reuse, particularly in arid regions. However, inadequately treated reclaimed water may pose health risks from waterborne pathogens, including gastrointestinal infections.

Application of a QMRA model for surface water treatment to investigate a waterborne outbreak of calicivirus

, 2009
The QMRA modelling tool developed by the Swedish Water & Wastewater Association was applied to investigate a probably waterborne outbreak of calicivirus that occurred in the municipality of Lilla Edet, Sweden, after a period with heavy rain.

Scenario-based assessment of fecal pathogen sources affecting bathing water quality: novel treatment options to reduce norovirus and Campylobacter infection risks

Frontiers in Microbiology
Wastewater discharge and runoff waters are significant sources of human and animal fecal microbes in surface waters. Human-derived fecal contamination of water is generally estimated to pose a greater risk to human health than animal fecal contamination,

Determination of Removal Efficiencies for Escherichia coli, Clostridial Spores, and F-Specific Coliphages in Unit Processes of Surface Waterworks for QMRA Applications

, 2018
The removal efficiencies of bacteria, bacterial spores, and viruses after a change in source water and water pH in coagulation were studied at pilot scale in coagulation with flotation, rapid sand filtration, and disinfection with UV and chlorine.
