  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • LIMS Key to Quality Data Management in Water Industry

    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 ...

  • 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 management for domestic rainwater harvesting systems in Fiji

    Health risks from drinking rainwater are relatively small in the developing world context, but action is needed to ensure water safety. Water safety plans (WSPs) use an approach to manage water quality that has shown signs of success with public and communal water supplies, but relatively little research has been done to investigate the application of WSPs to self-supply systems. The aim of this ...

  • Developing a water quality management model for karun and dez rivers

    More than one third of Iran’s total surface water of 94 billion m3 is flowing into the Khuzestan province but ironically most of its inhabitants are suffering from poor quality drinking water, especially during the summer months. More than 70% of the four million population of the khuzestan province, which includes the inhabitants of the provincial capital city of Ahvaz and the two major port ...

  • Toxicity Identification Evaluation (TIE) as a Tool for Water Quality Management

    Whole effluent toxicity (WET) testing has evolved into a critical element of many National Pollutant Discharge Elimination System (NPDES) permits issued to both industrial and municipal dischargers. Over 6,500 dischargers to both fresh and salt waters are required to conduct toxicity tests to determine if their effluent might be potentially toxic to organisms in the receiving system. While ...

  • 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 ...

  • A comparative assessment of institutional frameworks for managing drinking water quality

    The global burden of disease attributable to contaminated drinking water calls for effective strategies for ensuring drinking water quality. To characterize institutional and policy approaches towards water quality management, we compared national and sub-national institutional frameworks for drinking water provision and management in nine developing countries, focusing on roles, responsibilities ...

  • Quality Data Management: An Essential Component Of US Water Infrastructure

    The standards for environmental testing are more rigorous and far reaching than ever. At the same time, the U.S. water infrastructure has reached the age where replacement is critical. Laboratories and testing facilities trying to address both issues should consider implementing a Laboratory Information Management System (LIMS). A LIMS, which replaces paper-based systems, can increase sample ...

  • 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 ...

  • 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, ...

  • 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 ...
