  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Analysis of key aspects of the dispersion of industrial wastewaters to delimit environmental mixing zones

    In the VERTITOX research project (018/RN08/02.1), where the Principal Researcher (IP) of this application took part, a methodology for delimitation of environmental mixing zones of urban and industrial discharges was developed. That work allowed verification of the existence of critical issues in establishing the extent of these areas. Such issues lie in the statistical treatment of 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 ...

  • Principles for the application of the cost-effectiveness analysis in water quality sector

    Cost-effectiveness analysis (CEA) provides useful information for the cost and the environmental effectiveness of alternative management options in realising a given environmental goal. The purpose of this paper is to present factors that could be considered essential for the identification of the most cost-effective combination of the measures for water quality management. The reviewed ...

  • A system dynamics-based conflict resolution model for river water quality management

    Conflict is a disagreement among individuals or groups that differ in attitudes, beliefs, values or needs. Contemporary water resources management is a combined process of sharing water and resolving conflicts among decision makers and stakeholders. Stakeholders in this context refer to individuals, organizations, or institutions that have stakes in the outcome of decision related to water or ...

  • 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 ...

  • Fate of selected pharmaceuticals and their metabolites in soil aquifer treatment

    Through a series of long-term column experiments, the fate of three common pharmaceuticals (carbamazepine (CBZ), diclofenac, and indomethacin) and their major phase I metabolites in soil aquifer treatment (SAT) were monitored. CBZ concentration increased by a factor of two (from 37 to ca. 70 ng/L) regardless of the treatment conditions, and its metabolites, ...

  • Platypus Collects Water Quality Data in Record Time with Robotic Boats and In-Situ Equipment

    Overview Hired to monitor runoff from intensive greenhouse agriculture in the Netherlands, Platypus uses robotic boats and Aqua TROLL 600s to gather in a matter of days water quality data that otherwise would have taken weeks or months to collect. Challenge As population density increases, many countries wrestle with water quality management. The problem is particularly acute in the Netherlands, ...

  • Indirect potable water reuse: an alternative for water quality management in the Las Vegas Valley

    ABSTRACT The ever increasing population in Las Vegas Valley has spurred the development of new water management policies for providing water and wastewater infrastructure to address the consequent high demand for water and high amounts of wastewater generation. Current plans to address water demand include importation of water from Muddy and Virgin Rivers and northern counties, desalination of ...

  • Access, monitoring and intervention challenges in the provision of safe drinking water in rural Bihar, India

    This practical paper addresses the vital gap in water quality monitoring in Bihar. The study addresses an institutional weakness in the area of water quality management in rural Bihar, India. The study focuses on the role of access as a vital component in addressing water quality monitoring and interventions that has a huge impact on protecting community health in areas severely contaminated with ...

  • Surface water quality management using an integrated discharge permit and the reclaimed water market

    Water quality trading is a sustainable framework for surface water quality management. It uses discharge permits to reduce the total treatment costs. For example, the case of Gharesoo River in Iran shows that the nitrogen permit market between point and non-point sources is 37% more economical than the command and control framework. Nevertheless, the cost saving may be reduced to ...

  • Pilot plant study for one year: water quality management and algal control of sustainable urban stormwater ponds

    Pond structures as cost-effective "source control" drainage techniques that can be applied to reduce the risk of downstream flooding and to recycle stormwater. There are no widely accepted performance and water quality management data on stormwater ponds, yet there is a need for operation and maintenance guidelines, coupled with data on reliability, economics and public acceptance. The purpose of ...

  • Regulations and perspectives on disinfection by-products: importance of estimating overall toxicity

    Chemical disinfection of drinking water results in the formation of disinfection by-products (DBPs). This paper reviews evidence on the overall toxicity of disinfected water instead of focusing on the effects of individual DBPs. The possible health effects of ingesting DBPs include development of cancer and adverse reproductive/developmental outcomes. Only a few of the 600–700 chlorinated ...

  • Identification of indispensable components for a better drinking water quality management: Tunis case of study

    In order to reduce the number of operations for the assessment of potable water treatment, principal component analysis and hierarchical clustering are applied to large databases of raw and treated water of three treatment plants with various processes. It appears that the measurements can be divided into three clear groups, with a correlation higher than 0.8. The first contains salinity, ...
