Norwegian study on microbial source tracking for water quality control and pollution removal in constructed wetland treating catchment run-off
This study describes the first Norwegian microbial source tracking (MST) approach for water quality control and pollution removal from catchment run-off in a nature-based treatment system (NBTS) with a constructed wetland. The applied MST tools combined microbial analyses and molecular tests to detect and define the source(s) and dominant origin(s) of faecal water contamination. Faecal ...

Modelling the catchment-scale environmental impacts of wastewater treatment in an urban sewage system for CO2 emission assessment
Water shortages and water pollution are a global problem. Increases in population can have further acute effects on water cycles and on the availability of water resources. Thus, wastewater management plays an important role in mitigating negative impacts on natural ecosystems and human environments and is an important area of research. In this study, we modelled catchment-scale hydrology, ...

Whole Effluent Toxicity Testing
What is Whole Effluent Toxicity (WET) testing? Whole Effluent Toxicity (WET) testing is an important component of the U.S. Environmental Protection Agency’s (USEPA’s) integrated approach for detecting and addressing toxicity in surface waters. The National Pollutant Discharge Elimination System (NPDES) permit program, authorized by the Clean Water Act, controls water pollution by regulating ...

Using Permeable Eco-Paving to Achieve Improved Water Quality for Urban Pavements
This paper describes the planning, design and construction of a permeable pavement as a practical demonstration of the benefits of eco-paving in Australian environmental management. The paper addresses the use of permeable pavements as part of a Water Sensitive Urban Design that allows infiltration of stormwater, reduction of pollutants and slow reticulation of the stormwater to an ecologically ...

Tools to improve water quality
This post is part of a series on World Water Week, an annual event designed to draw attention to and discuss global water issues. Read more posts in this series. Agricultural production often comes at the expense of water quality. As my colleague, Mindy Selman, noted in a recent blog post, “Agriculture is the leading source of nutrient pollution in waterways—a situation that’s ...

Control Algae and Improve the Water Quality in Waste Stabilization Ponds
Due to population growth, accelerated urbanisation and economic development, the quantity of waste water generated is increasing globally. Mainly in low-income areas, a large proportion of the waste water is discharged directly in the environment. When the waste water is treated, the treatment plants may not remove certain pollutants that can have a negative impact on the people and ecosystem. ...

Farmington water pollution control authority case study
Performance History and Discussion The Farmington Water Pollution Control Authority (FWPCA) selected In-Pipe Technology to improve the performance of the WWTP by reducing sludge production and improving the nitrogen removal efficiency of the treatment process. Additional benefits of In-Pipe service include improving effluent water quality, reducing energy consumption at the plant and protecting ...

Environmental Situation in Africa
Abstract Africa The economic and social needs of Africa depends more on its environmental resources but these natural resources are seriously declining and that is really effecting the entire region. Sustainable development in this rapidly changing region has become an imperative, and must take place in the complex context of a diverse and changing ecosystem, political transition and evolution ...
