  • Data Requirements for Ground Water, Surface Water, and Leachate

    It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...

  • Data Flows

    Metering only tells us our total water usage, but the latest technology can tell us so much more, according to Dene Marshallsay and Mark ...

  • Strategic Planning for Water Loss Reduction with Imprecise Data

    Water utilities particularly in the developing countries continue to operate with considerable inefficiencies in terms of water and revenue losses. With increasing water demand and scarcity, utilities require effective strategies for optimum use of available water resources. Often the information needed for strategic planning is inadequate and decisions have to be made on the basis of limited and ...

  • 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, ...

  • Data mining techniques for water ecotoxicity classification for application on water resources management

    Among the various forms of action that promote sustainability, technological innovation can be considered one of the most important. This paper applied data mining techniques to discover knowledge in the field of water quality monitoring data, providing useful and relevant support for decision-making in environmental management systems. At the current stage of research, a predictive modelling ...

  • Water Diaries: generate intra-household water use data – generate water use behaviour change

    With the current ‘water crisis’ essentially a crisis in water management, the need to clearly understand domestic water use is critical. In recent years there has been a growing awareness of the need to manage demand in all water sectors. However, demand mechanics at the intra-household scale are not well understood, with many utilities adopting a ‘command and control’ ...

  • Progress on water data integration and distribution: a summary of select US Geological Survey data systems

    Critical water-resources issues ranging from flood response to water scarcity make access to integrated water information, services, tools, and models essential. Since 1995 when the first water data web pages went online, the US Geological Survey has been at the forefront of water data distribution and integration. Today, real-time and historical streamflow observations are available via web ...

  • On data requirements for calibration of integrated models for urban water systems

    Modeling of integrated urban water systems (IUWS) has seen a rapid development in recent years. Models and software are available that describe the process dynamics in sewers, wastewater treatment plants (WWTPs), receiving water systems as well as at the interfaces between the submodels. Successful applications of integrated modeling are, however, relatively scarce. One of the reasons for this ...

  • 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 ...

  • Water distribution model for decision-making with updatable data links

    From February 2011 to December 2012, the Tallinn Water Company, AS Tallinna Vesi (ASTV), aimed at improving the previous hydraulic model creation procedures so that the model can be operatively updated through the available geographic information system, client information system (Navision), supervisory control and data acquisition system (SCADA). The goal of the project was to analyse various ...

  • Water Quality Data Logger for Monitoring Coal Mine Runoff

    Water Quality Monitoring Solutions from dataTaker CAS DataLoggers provided an intelligent water quality data logging solution for an open-cut coal mine to monitor high salinity water runoff into local retaining ponds with a Water Quality Data Logger. The water from these retention ponds could only be released into the local river system when it was of sufficient quality to have no effect on the ...

  • Establishing the First Validated Dataset of North American Water Utility Water Audit Data

    The American Water Works Association‟s (AWWA) Water Loss Control Committee (WLCC)assembled in 2011 an initial dataset of Water Audit data from 26 water systems from the United States and Canada. This effort represents the initial phase of a project that ultimately aims to establish North American water industry benchmarks for water loss control, while promoting the use of standardized water ...

  • Data management for integrated water resources management in Central Asia

    Information technologies can act as technical artifacts and can facilitate stakeholder communication, supporting decision making in a complex societal context. The water sector is one such example where limited water resources are threatened by climate change and growing competition for resources between sectors, regions and countries. Attempts to improve water governance and management through ...

  • Assessment of data and parameter uncertainties in integrated water-quality model

    In integrated urban drainage water quality models, due to the fact that integrated approaches are basically a cascade of sub-models (simulating sewer system, wastewater treatment plant and receiving water body), uncertainty produced in one sub-model propagates to the following ones depending on the model structure, the estimation of parameters and the availability and uncertainty of measurements ...

  • A method for deriving water‐quality benchmarks using field data

    The authors describe a methodology that characterizes effects to individual genera observed in the field and estimate the concentration at which 5% of genera are adversely affected. Ionic strength, measured as specific conductance, is used to illustrate the methodology. Assuming some resilience in the population, 95% of the genera are afforded protection. The authors selected an unambiguous ...
