  • 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, ...

  • 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 ...

  • EPA Revises Water Quality Criteria

    Tens of thousands of members of the regulated community from industrial facilities with air emissions and wastewater discharges to municipal wastewater treatment plants, to hazardous waste site managers may be affected by changes to the WQC. US EPA Water Quality Criteria (WQC) which attempt to protect human health and the environment associated with the US waters, serve as the basis for most ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...


  • Developing a national water quality criteria system in China

    Water quality criteria (WQC) form a scientific basis for the development of water quality standards. The study of WQC in China has been insufficient. This mini review introduces the progress that has been made towards the establishment of a WQC system in China. A systematic WQC study has been ongoing in China for several years, mainly referring to the WQC system in the United States. Some ...

  • An Islamic perspective on water quality: a case of Malaysia

    Water pollution has long been a crisis of life-threatening proportion in many Muslim countries. It is therefore timely to determine the role of traditional Islamic jurisprudence in outlining the water quality standards. This study examines the Islamic and scientific approaches in appraising water quality. More specifically, this study used the Taharah–Najasah (T–N) standards ...

  • 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 ...

  • A coupled model for water resources allocation regarding water quality control

    In this study, a fuzzy credibility constrained programming (FCCP) model is developed for water quantity and quality management with uncertainties in water quality parameters. The proposed method could reflect not only inexact uncertainties in the objective function, variables and parameters, but also fuzzy uncertainties in the right-hand side. Credibility levels which represent satisfaction ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • New USEPA water quality criteria by 2012: GOMA concerns and recommendations

    The Gulf of Mexico Alliance (GOMA) was tasked by the five Gulf State Governors to identify major issues affecting the Gulf of Mexico (GoM) and to set priorities for ameliorating these problems. One priority identified by GOMA is the need to improve detection methods for water quality indicators, pathogens and microbial source tracking. The United States Environmental Protection Agency (USEPA) is ...

  • Accounting for metal bioavailability in assessing water quality: A step change?

    Bioavailability of metals to aquatic organisms can be considered to be a combination of the physicochemical factors governing metal behavior and the specific pathophysiological characteristics of the organism's biological receptor. Effectively this means that a measure of bioavailability will reflect the exposures that organisms in the water column actually “experience”. This is important ...

  • Drinking water in rural India: a study of deficiency, quality and some social implications

    There is no doubt that accessibility of drinking water for rural households in India has increased over the decades, partly owing to concerted efforts by the state and partly owing to a rise in income of the people. Public provision of drinking water is primarily made through the tap whereas private provision is through the tube well. Households opt more for a tube well than for other sources ...

  • Guidelines for drinking water quality Addendum to Vol 2 Health Criteria

    In 1984 and 1985, the World Health Organization (WHO) published the first edition of Guidelines for drinking-water quality in three volumes. The development of these guidelines was organized and carried out jointly by WHO headquarters and the WHO Regional Office for Europe (EURO). In 1988, the decision was made within WHO to initiate the revision of the guidelines. The work was again shared ...

  • Methodology for Forensic Investigation of Potable Water Quality in Municipal Distribution Systems

    Abstract During routine regulatory potable water quality sampling in distribution systems related to the Total Coliform Rule, utilities can sometimes experience anomalous detections of total coliform bacteria and/or fecal coliform bacteria in the distribution system samples. Frequently, the regulatory-required retesting of the same sample locations reveals no detection of bacteria, and thus ...

  • Water Quality Risk Assessment for Dredging Operations, Plymouth Sound, UK

    ABSTRACTAs part of a formal Environmental Impact Assessment for a port development project in Plymouth Sound, UK, the potential risk of a deterioration in water quality from capital dredging was informed by the application of a probabilistic risk approach. In the absence of UK statutory sediment quality guidelines (SQGs) to assess acceptability of dredging operations, non-statutory guidelines are ...

  • 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 ...

  • A New Strategy to Improve Water Quality—One Targeted Watershed at a Time

    Water quality in the United States remains a major environmental and policy challenge. Water pollution is also a growing and serious problem across much of the world. Tackling water quality problems, particularly from diffuse sources such as agricultural farm fields, is a substantial challenge and much can be learned from the U.S. experience. ...

  • Evaluation of Drinking Water Quality by EPA-Certified Graphite Furnace AAS

    With the development of residential homes in all parts of the World, there is a need for accurate, high-volume measurements of various Metals in the Drinking Water that people in these residences will live on. Accurate measurements of specific metals will determine the types of pipes used, the lifetime of the plumbing, the potential for mineral stains on porcelain, and more importantly, the ...

  • Bottling water, greening farmers: the socio-technical and managerial construction of a 'dispositif' for underground water quality protection

    This paper proposes the description and analysis of the dynamics of an innovation process, which, over ten years ago, enabled a mineral water company to start protecting its underground water and to overcome a classical negative externality problem of no point-source nitrogen pollution. Based on methodological reflection and discussion of the dynamics of socio-technical arrangement in the ...
