  • 3 Scientific Tools to Help You Better Understand Your Water Quality

    There are many ways of testing and understanding your water quality with online scientific tools and models. One such resource is the National Water-Quality Assessment (NAWQA) project run by the U.S. Geological Survey (USGS). The project, which was founded in 1991 to develop reliable information about water sources to support decisions on water quality management ...

  • Why are we monitoring nutrients at different depths?

    Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...

  • Why You Should Monitor Groundwater?

    What is groundwater? Groundwater is water that is stored below the earth’s surface. When rain or other sources of water come into contact with the ground, the majority of it travels below the surface. Though much of this moisture is then absorbed by plants or returned to the atmosphere (through infiltration), some water will travel deeper beneath the surface – where it ...

  • European waters - assessment of status and pressures

    EEA 2012 'State of Europe's water' assessments 2012 is the European year of water in which the European Commission published its 'Blueprint to safeguard Europe's waters' (referred to hereafter as the Blueprint) comprising reviews of the Water Framework Directive (WFD) (2000/60/EC), water scarcity and drought and adaptation to climate change policies. To accompany and inform the blueprint, ...

  • Assessing social concerns in water tariffs

    In the European Union, water supply services are referred to as ‘services of general interest’, meaning that they are subject to multiple, potentially conflicting, public service obligations. This paper considers empirical data for Portuguese municipalities and provides a comprehensive approach to assessing the social dimension by evaluating whether the concerns of universal access ...

  • Assessment of water loss in Harare, Zimbabwe

    A major challenge facing water utilities is the high level of water losses, which affects the financial viability and adequacy of water in the system. A study was carried out from January to May 2012 to characterize water losses in selected areas of Harare, Zimbabwe. Assessment of the contribution of water leakage to total water loss was carried out through water audits in four selected ...

    Untitled Document A close look at all aspects of your water- and wastewater-treatment systems can reveal opportunities for cost savings, improved operation, reduced ...


  • Water Quality Assessment and Onshore Development in Tropical Waters

    Standards for bacteriological recreational water quality in Puerto Rico are those proposed by US EPA. The standard for primary contact recreational use has both single-sample limits and running- average threshold limits based on historical data developed for the specific site. La Parguera is the site of a Special Marine Reserve and counts among its unusual habitats a phosphorescent bay, important ...

  • Europe`s environment — An assessment of assessments

    The European Environment Agency (EEA) has produced four pan-European 'state of Europe's environment' reports in support of the United Nations Economic Commission for Europe (UNECE) 'Environment for Europe' process (1). Over time, and in conjunction with a host of other reports (including the additional four five-yearly state and outlook reports produced by the EEA for its geographical area (2)), ...

  • Sharing Transboundary Waters - an integrated assessment of equitable entitlement : the Legal Assessment model

    More than 40 per cent of the world’s population -- including some of the most poverty stricken -- depend upon water that originates in sources beyond their national borders. How can they be assured access to adequate water supply and sanitation if their State is subject to the activities of other sovereign entities? When a transboundary watercourse State (TWC State) uses more than its ...

  • An interdisciplinary approach to the assessment of water recycling technology options

    Whilst work on the development of engineering options for water recycling has continued apace over the last decade, less attention has been paid to the problem of selecting appropriate technologies for particular applications. This paper firstly reviews the motivations for a cross-disciplinary approach to technology selection in this context, highlighting the process of translating research ...

  • A preliminary water footprint assessment of copper production in China

    Scarcer water resources, stricter water regulations, decline in ore grade and increasing controversy on water use between local communities and mining operators have raised awareness of good water stewardship as being vital to running commercially viable mining operations. Water footprint assessment (WFA) is a holistic methodological framework that allows detailed quantification of direct and ...

  • Assessment of source tracking methods for application in spring water

    For discriminating between human and animal faecal contamination in water, microbial source tracking (MST) approaches using different indicators have been employed. In the current study, a range of 10 such MST indicators described in the scientific literature were comparatively assessed. Bacteriophages infecting host strains of Bacteroides (GA-17, GB-124 and ARABA 84) as well as ...

  • Assessing human resources renovation needs in water utilities

    Human resources are one of the most important assets of water utilities (WUs), being responsible for assuring systems management and playing an important role in the tacit forms of organizational knowledge. In organizations with responsibility for managing extensive, diverse infrastructure with long life-cycles, with adequate service and acceptable risk levels, knowledge transfer between peers ...

  • Challenges to International Waters; Regional Assessments in a Global Perspective

    The GIWA Final Report provides a comprehensive review of the most important findings from the GIWA regional reports. It summarises the major transboundary concerns and their environmental and socio-economic impacts. To better understand these concerns and develop solutions to address them, the Report identifies the root causes and draws policy relevant conclusions. It also outlines knowledge gaps ...


  • Component-holistic condition assessment of water distribution networks

    The work presented herein presents an expanded methodology for imprinting the condition of an urban water distribution network (WDN). Even though the majority of past research efforts related to WDNs deal with water mains (WMs), only a small part of the research studies have considered house connections (HCs) in the analysis and very few researchers have examined how the failure of pipe ...

  • Assessing water quality in Europe using stratification techniques

    This report aims to provide information in relation to the trends of major nutrients in rivers. It focuses both on the trends considered as indicators of water quality status and on the possible differences in trends in relation to main driving forces (agriculture, urbanisation). Referring to the driving forces — pressures — state — impact — response (DPSIR)assessment framework of the EEA, the ...

  • A novel integrated assessment methodology of urban water reuse

    Wastewater is no longer considered a waste product and water reuse needs to play a stronger part in securing urban water supply. Although treatment technologies for water reclamation have significantly improved the question that deserves further analysis is, how selection of a particular wastewater treatment technology relates to performance and sustainability? The proposed assessment model ...
