  • Where Is the Most Water Reuse Taking Place?

    Water reuse is becoming increasingly important as water scarcity becomes prevalent throughout the world. Whether it’s referred to as water reuse, water recycling, water reclamation, or another name, the resulting purified wastewater can be used in many applications, both potable and nonpotable. In some places, water reuse has been slow to catch on, particularly because of the so-called ...

  • Water quality management in the Balabandere Creek catchment

    Understanding hydrological and hydrochemical processes has become increasingly more challenging with high rates of population growth and subsequent alteration of the environment. In addition to maintaining monitoring networks to assess the general state of water quality, detecting trends, and computing pollutant transport, process-level information is needed to evaluate factors that affect the ...

  • Risk analysis of seasonal stream water quality management

    Seasonal discharge programs, which take advantage of temporal variation of stream assimilative capacity, are cost effective. However, these seasonal discharge control programs should not increase the risk of water quality violations. A method is presented to estimate the allowable pollutant loads under both seasonal and non-seasonal discharge control programs for a single discharger that ...

  • Forum: Urban storm water management: quantity and quality

    A watershed can experience extra stresses due to the activities of urbanisation such as new land developments. This brief Forum paper raises two matters for discussion concerning best management prectices (BMPs) in this area: firstly, that it would be beneficial to have more continuous monitoring programs put in place to test and document the effectiveness of various BMPs in various regions; and ...

  • Recycled Water Quality

    Matching recycled water quality to beneficial uses requires an understanding of health and environmental requirements. Measures to achieve appropriate recycled water quality are determined firstly by treatment. The degree of treatment depends in part on the source and the hydraulic and biochemical characters of the wastewater. Overall recycled water outcomes may also be controlled ...

  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...

  • Ensuring Water Quality in Africa

    Water is essential for life, and “access to safe water is a fundamental human and, therefore, a basic human right.” With this statement and his address on World Water Day in 2001, United Nations Secretary-General Kofi Annan put a spotlight on what continues to be a global problem: clean water. This year completes the UN “Water for Life” international decade for ...

  • Drinking Water Quality

    The quality of drinking-water is a powerful environmental determinant of health. Drinking-water quality management has been a key pillar of primary prevention for over one-and-a-half centuries and it continues to be the foundation for the prevention and control of waterborne diseases. Water is essential for life, but it can and does transmit disease in countries in all continents – from the ...

  • Mining Water Quality Application

    Isaac Plains Coal Mine Isaac Plains is an open cut coal mine, in Northern Queensland, Australia. The Isaac Plains Project operates under an Environmental Authority (EA). One of the environmental monitoring requirements which must be met is monitoring water. These include potable water, mine affected water, natural creek flows, water releases, groundwater and the receiving environment. The ...

    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, ...

  • Water Quality & Treatment Centers

    A look at the quality of water and the importance of inspecting the integrity of water treatment centers. Water…clear…cold…refreshing. It’s often your “go-to” beverage for quenching thirst after a vigorous activity. We are very fortunate that often within arm’s reach, rests a glass of water. Without hesitation or worry, you can pick it ...

  • Managing water quality impacts from drought on drinking water supplies

    Droughts, which are difficult to predict, are a natural feature of the hydrology in most regions. Climate change, however, has the potential to increase the frequency and magnitude of future droughts. While the lack of water availability during droughts is widely publicized, there are equally severe water quality impacts that occur during and after droughts as well. Recent droughts have led to ...

  • MIKE 11 model-based water quality model as a tool for the evaluation of water quality management plans

    Water quality models are important tools to test the effectiveness of alternative management plans on the water quality of water bodies. The main aim of this study was to develop and demonstrate use of a water quality model as a tool for evaluation of alternative water management scenarios for the river basin of Beijing, China. Considering Lao Hewan river landscape water circulation patterns and ...

  • Water Quality Benefits of Grass Swales in Managing Highway Runoff

    ABSTRACTGrass swales are a vegetated stormwater management technology that can remove surface runoff contamination through sedimentation, filtration by the grass blades, infiltration to the soil, and likely some biological processes. Two full-scale grass swales in the median of a four-lane highway were monitored during 18 storm events to characterize the overall performance of grass swales as a ...

  • Management of unregulated agricultural nonpoint sources through water quality trading market

    Water quality trading (WQT) could be an innovative policy to incentivize farmers to implement best management practices (BMPs) for their activities. This study focused on assessment of involving unregulated agricultural nonpoint sources (NPS) into the WQT market in Gharesoo watershed in the west of Iran. It also proposes a methodology to determine location-based trading ratios as well as ...
