In the southern regions of Mediterranean Europe, the greatest part of water resources for supply systems come from artificial reservoirs. Eutrophication is one of the most serious problems affecting the quality of water stored in reservoirs. A simplified approach that includes water quality aspects as water use limiting factors in a multi-reservoir optimization model can be achieved by adoption...

A study has been conducted to illustrate examples of water quality problems to vulnerable communities in Limpopo Province of South Africa (SA) and management practices and strategies. Pollution of water sources is a major threat to the scarce water resources in the province. This severely affects water quality and impacts negatively on public health particularly in remote rural communities that...

Water and sanitation in hospitals are a serious forgotten issue. Water quality impacts the performance of the hospitals and its deterioration leads to drastic health service deterioration affecting infection control programs, occupational health and safety of the workers as well as the safety of the hospital buildings and its anticipated life service. The integrated environmental management in ...

This paper presents the first results of a study which investigates river basin water quality management based on the ability of GIS to integrate different data sources into a common geographical database. The overall objective of this research is to develop a scheme for water management and improve the likelihood of detecting water quality trends and to determine if variability in water qualit...

Many agencies, including the U.S. Army Corps of Engineers, are responsible for ensuring that national water quality standards are met. The Corps manages and monitors water quality of all waters within Corps jurisdictions outlined in Water Quality Management Plans, including traditional field sampling (water, sediment, and biological) and measurement of physical parameters. However, these tradit...

Water quality monitoring is important for identifying public health risks and ensuring water safety. However, even when water sources are tested, many institutions struggle to access data for immediate action or long-term decision-making. We analyzed water testing structures among 26 regulated water suppliers and public health surveillance agencies across six African countries and identified fo...
