The goal of this study was to monitor the presence of adenovirus in rivers and lakes used for recreation and as a source for the public water supply in the city of Goiânia, Brazil, in addition to carrying out a correlation analysis of the seasonality of adenovirus gene detection and water quality parameters based on yearly monitoring. We collected 54 water samples from two lakes and two rivers. Th...... hiện toàn bộ
Physicochemical and Bacteriological Water Quality Across Different Forms of Land Use on the Mahafaly Plateau, MadagascarSpringer Science and Business Media LLC - Tập 7 - Trang 111-124 - 2014
Jean R. Rasoloariniaina, Jörg U. Ganzhorn, Noromalala Raminosoa
The sub-arid southwest of Madagascar is one of the world’s biodiversity hotspots combined with exceptional poverty and high risk of further temperature increase that will aggravate the living and health conditions of the people. As bases for future water management, we measured the physicochemical and microbiological quality of water sources across different forms of land use in the protected Tsim...... hiện toàn bộ

Non-revenue water (NRW) in urban water distribution networks is a very demanding task to handle. NRW impacts are economic (lost revenues), environmental (water and energy losses) and social (inefficient water pricing policies not based on the actual water consumption profile/patterns). To deal with NRW, water utilities turn to water audit tools and water loss control methods. In this context, WATE...... hiện toàn bộ
Assessment of the Contribution of N-Fertilizers to Nitrate Pollution of Groundwater in Western Iran (Case Study: Ghorveh–Dehgelan Aquifer)Springer Science and Business Media LLC - Tập 7 - Trang 143-151 - 2014

Nitrate pollution of groundwater resources has increasingly become a global concern. Groundwater from the Ghorveh-Dehgelan aquifer serves as the main source of water supply for drinking and irrigation within the province of Kurdistan (western Iran). This study investigated (1) groundwater nitrate status as well as the pollution sources and (2) the spatial extent of groundwater nitrate pollution in...... hiện toàn bộ
Comparative Investigation of Water Quality Parameters of Aerial & Rangat Bay, Andaman Islands Using In-Situ Measurements and Spatial Modelling TechniquesSpringer Science and Business Media LLC - Tập 5 - Trang 57-67 - 2013

Aerial Bay and Rangat Bay witness extensive and diverse activities such as tourism, shipping and fisheries. These activities along with domestic discharge may significantly affect the seawater quality in the bays. Therefore seawater samples were analyzed to comprehend the physicochemical and biological variables and its sources that affected the seawater quality at both the bays. The land-use/land...... hiện toàn bộ
Does Above-Normal Precipitation Reduce the Impact of Mountain Cattle Grazing on Watershed Algae and Bacteria?Springer Science and Business Media LLC - Tập 4 - Trang 105-112 - 2012
Robert W. Derlet, John R. Richards, Charles R. Goldman
Cattle grazing is believed to have a harmful impact on high elevation Sierra Nevada mountain (Sierra) watersheds. During normal precipitation years, the prevalence of suspended stream and small lake aquatic coliforms and E. coli is significantly increased in cattle-grazed areas, and periphytic algae biomass is amplified. In addition, large numbers of E. coli are found attached to algae only in cat...... hiện toàn bộ
