  • 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 ...

  • 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 ...

    WEFTEC  has just  wrapped up its 2012 conference – the largest meeting of its kind in North America.  The Water Environment Federations’ annual meeting has again delivered comprehensive water quality education and training to thousands of water quality professionals.  The leading discussions at WEFTEC ...

  • 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 ...

  • 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 ...

  • 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, ...

  • 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 ...

  • Lag time in water quality response to best management practices: a review

    Received for publication March 20, 2009. Nonpoint source (NPS) watershed projects often fail to meet expectations for water quality improvement because of lag time, the time elapsed between adoption of management changes and the detection of measurable improvement in water quality in the target water body. Even when management changes are well-designed and fully implemented, water quality ...

  • Water quality management of aquifer recharge using advanced tools

    Managed aquifer recharge (MAR) with recycled water or other alternative resources is one of the most rapidly growing techniques that is viewed as a necessity in water-short areas. In order to better control health and environmental effects of MAR, this paper presents two case studies demonstrating how to improve water quality, enable reliable tracing of injected water and better control and ...

  • Application of water quality indices to define surface water quality in Tehran

    Tehran is one of the capitals of the world that is not situated around a river, therefore surface water discharges into a network of natural streams and even some artificial canals. Owing to the lack of sewerage system, part of the sewage runs to the network of streams without any control. The aim of this work is to identify a baseline for the water quality, which will then help policy-makers and ...
