Wastewater must be treated to remove harmful pathogens and chemicals before it can be released to the environment, but the cost of proving that all pollutants have been removed is prohibitive because potentially thousands of separate chemicals would have to be measured…
Before treated wastewater can be discharged to the environment, utilities are required to perform a direct toxicity assessment (DTA), which usually requires that live aquatic animals, such as fish, swim in the clean discharge water for 4-10 days while their growth and activity are observed and measured…
The ADWG has methods for predicting risks to water quality, but these were not developed for managing extreme climate-change driven weather events such as bushfires or floods…
The ADWGs include methods and strategies for calculating all types of risks to water quality but lack guidance for managing extreme weather events…
Blue-green algae (cyanobacteria) reduce water quality especially when they bloom and form high numbers of cells which produce toxins, and taste and odour compounds…
Components of dissolved organic matter (DOM) and dissolved organic nitrogen (DON) in source waters can react with disinfecting chlorine or chloramine to form nitrogenous disinfection byproducts (n-DBPs) which might be toxic and hazardous to health…
Climate change is depleting water resources, while population increases drive demand for additional recreational facilities, particularly in the vicinity of urban centres…
Blue-green algae are a nuisance, especially when they bloom and grow to high numbers in water storages and reservoirs…
This research discusses various water quality risk management techniques and proposes a step-by-step catchment risk assessment methodology that is compatible with the Australian Drinking Water Guidelines…
