  • Chemical pollutants in water emerge

    Recent advances in contaminant identification methodologies, sampling instrumentation, and analytical chemistry have caused an explosion of knowledge about the presence of previously undetected organic micropollutants. While it doesn"t follow that the mere presence of chemical contaminants results in harm, public health experts, regulators, and others aren"t sitting idly by. Given the necessity ...

  • Constituents of Emerging Concern: An Overview

    Emerging constituents of concern have been with us from the beginning of the environmental era 45 years ago. They were behind the 1974 Safe Drinking Water Act. They are behind our struggle with disinfection byproducts. They were behind the development of the 129 (126) priority pollutants. They were behind RCRA and the Superfund. Now they are “emerging” as endocrine disruptors, pharmaceuticals, ...

  • A real-time, rapid emergency control model for sudden water pollution accidents in long-distance water transfer projects

    A real-time, rapid emergency control (EC) model is proposed to cope with sudden water pollution accidents in long-distance water transfer projects. The EC model outputs the method of EC based on pollutant properties. A generalized form of EC model is proposed and tested with a demonstrative project. The rapid prediction formulas of emergency control parameters (ECPs) are proposed under ...

  • The Challenge of the Future: Operating Emerging Disinfection Technologies

    ABSTRACTThe Clean Water Act (1972 and 1977) established the basis for regulating pollutant discharges into the waters of the United States. This Act contains many provisions regulating pollutant discharges and surface water quality in the United States. This act has also been modified by numerous revisions and amendments since it was enacted in 1972. The National Pollutant Discharge Elimination ...

  • A comparison of disinfection performance and cost for various process combinations to disinfect reclaimed water

    For reclaimed water disinfection, pathogen reduction to acceptable public health risk levels is the primary objective. A second emerging objective is the ability to destroy trace pollutants (endocrine disrupters (EDCs), pharmaceutically active compounds (PhACs)) at a reasonably low cost. The WateReuse Foundation’s Innovative Reclaimed Water Treatment Project (WRF 02-009) is searching for ...

  • Screening of pharmaceuticals in surface water bodies of the Pampas region of Argentina

    Pharmaceuticals have been included among emerging pollutants due to their continuous input in aquatic environments by wastewater discharges. The aim of the present study was detecting and analysing concentration levels of five commonly used pharmaceuticals in surface water bodies of the Pampas region of Argentina. Analyses were done on the soluble fraction by liquid chromatography with mass ...

  • 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 ...

  • The EU water challenge: Every Drop Counts, A review of the EU’s largest environmental conference

    Every year as the summer approaches, EU policy makers, public authorities, NGOs, industry and private citizens gather at Green Week, the main environmental event of the European Commission. This year, from May 22-25, the 12th edition of Green Week consisted of a series of conferences on water issues and challenges. As water resources suffer increasing strains in the region, the European Union is ...

  • Could EB irradiation be the simplest solution for removing emerging contaminants from water and wastewater?

    Newly observed presence of ‘emerging contaminants’, defined also Compounds of Emerging Concern, chemicals without regulatory status and which impact on environment and human health are poorly understood has been amply reported in wastewater and aquatic environments. ‘Conventional’ water pollutants have been described for decades and their impact on human health and the environment are known; ...

  • Neptune project deliverable D3.4

    Concept of mobile analytical unit WWTP are the major point source for discharge of pollutants in surface water, and consequently impact on the new focus legislated by the WFD. The emerging interest on organic (eco-)toxic compounds requires characterizing treated effluent and treatment technologies concerning ecotoxicologic aspects and micropollutants. The potential of emerging ...

  • Searching for a sustainable arsenic mitigation strategy in Bangladesh: experience from two upazilas

    Arsenic concentrations of tubewell water that exceed the Bangladesh Drinking Water Standard pose a serious health problem for millions of people in Bangladesh. Groundwater is the source of drinking water for 98% of the population. The main object of the study was to review the status of the provided options, which were distributed during 1999?2001 in two upazilas. It was observed that ...

  • Removal of indigenous coliphages and enteric viruses during riverbank filtration from highly polluted river water in Delhi (India)

    Emerging countries frequently afflicted by waterborne diseases require safe and cost-efficient production of drinking water, a task that is becoming more challenging as many rivers carry a high degree of pollution. A study was conducted on the banks of the Yamuna River, Delhi, India, to ascertain if riverbank filtration (RBF) can significantly improve the quality of the highly polluted surface ...

  • Natural attenuation potential of selected hydrokarst systems in the Carpathian Mountains (Romania)

    We examined the potential for natural attenuation of ten hydrokarst systems (HKS) in three mountain units in the Carpathian Mountains. We sampled in places where water enters below ground and where water emerges back to the surface in springs and is used as drinking water by the local communities. Water samples were used to assess the degree of chemical and microbiological pollution. Although ...

  • On-site evaluation of the removal of 100 micro-pollutants through advanced wastewater treatment processes for reuse applications

    The next challenge of wastewater treatment is to reliably remove micro-pollutants at the microgram per litre range in order to meet reuse applications and contribute to reach the good status of the water bodies. A hundred priority and relevant emerging substances were measured to evaluate at full-scale the removal efficiencies of seven advanced treatment lines (one membrane bioreactor process and ...

  • Dose projection using dispersion models

    Dose projection is a tool for decision making in the case of a nuclear emergency situation. In this work the dose projection software developed for the Krsko NPP located in Slovenia is described. This software can be used for a quick emergency evaluation in the case of a hypothetical pressurised water reactor accident, and for emergency exercises. The software was developed to estimate reactor ...

  • Priority organic pollutants in the urban water cycle (Toulouse, France)

    Application of the European Water Framework Directive requires Member States to have better understanding of the quality of surface waters in order to improve knowledge of priority pollutants. Xenobiotics in urban receiving waters are an emerging concern. This study proposes a screening campaign of nine molecular species of xenobiotics in a separated sewer system. Five sites were investigated ...

  • Advanced Oxidation Processes (AOPs) for reduction of organic pollutants in landfill leachate: a review

    Uncontrolled municipal landfill leachate during landfilling can seriously pollute groundwater, surface water and soil. Over the past decades, a variety of Advanced Oxidation Processes (AOPs), primarily utilising hydroxyl radicals to effect water purification, have been frequently investigated for treatment of landfill leachate. This paper first summarises the typical characteristics of organic ...
