  • 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 ...

  • 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 ...

    A key part of HL's contract with Dwr Cymru Welsh Water to install, operate and maintain a large network of telemetred reservoir level and compensation flow gauges, a suite of HL's software packages was also supplied to each of the three operational areas for managing time-series data and processing stage-discharge data into a long-term flow record archive. HL's HydroLog4 and Gauger 2 packages ...

  • 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 ...

  • Employing flexible data management solutions that deliver improved productivity and quality in the water and environmental industry

    This article will discuss the industry trends and challenges environmental monitoring organizations face today and will demonstrate how the use of a Laboratory Information Management System (LIMS) allows managers to make informed decisions to improve throughput, resolve environmental issues and risks faster, all while enabling organizations to comply with strict regulatory guidelines. An ...

  • 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, ...

  • Heterogeneity of water quality in Huai River, China by using bio-monitoring data

    A new approach by combining bioindicators (BiI) and biotic indices (BIs) for evaluating water quality is presented in this paper. It is then applied to the Huai River Basin (HRB), China, which is well-known globally for its heavy anthropogenic influences. Results indicate that the spatial distribution of BI-indicated water quality has roughly the same pattern as that shown by BiI, but the ...

  • Aqua data: automatically capturing, mapping & sharing latest water quality data on the web

    Abstract This year Shoalhaven City Council (SCC) received the Local Government Award for Excellence in Overall Environmental Management at the prestigious United Nations of Australia World Environment Day Awards. In part this was in recognition of the considerable amount of time and money SCC invests on monitoring and reporting Water Quality across its Drinking Water, Effluent Treatment, ...

  • 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 ...

  • 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 ...

  • Assessment of water resources management and quality of El Salam Canal, Egypt

    The Government of Egypt implemented El Salam Canal project to reuse drainage water, to create new communities along the Canal and to re–chart Egypt's population map. The objectives of the present study are to evaluate the quantity of the drainage water which feed El–Salam Canal, and the quality of water discharge through the course of El Salam Canal. This paper assesses water quality of El Salam ...

  • 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 ...

  • 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 ...

  • 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 ...
