Water quality assessment of a polluted urban river
Urban rivers in Latin America are heavily impacted by human activities that affect their functions and services. This paper shows the results of a water quality assessment for the Reconquista River, the second most polluted urban river in Argentina. They allowed the identification of the main processes of transport of pollutants and the prioritisation of different areas of the basin for ...

Integrated frameworks for assessing and managing health risks in the context of managed aquifer recharge with river water
Integrated assessment and management of water resources for the supply of potable water is increasingly important in light of projected water scarcity in many parts of the world. This paper develops frameworks for regional‐level waterborne human health risk assessment of chemical and microbiological contamination to aid water management, incorporating economic aspects of health risks. Managed ...

Study: High Drug Levels Found in the Hudson River
Preventing contamination is first line of defense as researchers seek better wastewater treatment A collaborative study on pharmaceutical contamination distributions in the Hudson River published this year found that levels of some drugs were high enough to potentially harm aquatic life. The study, conducted by the United States Environmental Protection Agency (EPA), Riverkeeper, ...

Identification of pathogen bacteria and protozoa in treated urban wastewaters discharged in the Ebro River (Spain): water reuse possibilities
The aim of this research work is to identify the presence of pathogens, bacteria and protozoa, in different treated urban wastewaters and to relate biological pollution with the processes used in wastewater treatment plants. A study of the possibilities for water reuse is carried out taking into account bacterial and parasite composition. The analysed bacteria and protozoa are: Enterococcus ...

Application of diffusive gradients in thin films and core centrifugation methods to determine inorganic mercury and monomethylmercury profiles in sediment pore water
A diffusive gradient in thin films (DGT) is an in situ sampling technique for the quantitative analysis of contaminant concentrations that is based on the diffusion and adsorption of contaminants onto resin gels. In the current study, a DGT technique was applied to measure total mercury (Hg) and monomethylmercury (MMHg) concentrations in lake and coastal sediment pore waters and to compare ...

Answers to questions about oil waste in California aquifers
California, the country's third-largest oil-producing state, has improperly given oil companies more than 2,500 permits to inject production fluids and oilfield waste into underground water supplies that are used for drinking water or irrigation, state records show. Nearly half of those disposal wells were approved or first started injections in the last four years under Gov. Jerry Brown, an ...

Anglian water Cryptosoridium outbreak - Case Study
Pitsford Drinking Water Site, England In June 2008, a rabbit was located in the wash water tank at the Pitsford Drinking Water Plant of Anglian Water, leading to contamination of the treatment works with Cryptosporidum, a chlorine resistant parasitic micro-organism. The parasite was detected on June 24 and, following consultation with health and local authorities, a notice to boil drinking water ...
