  • Groundwater data network interoperability

    Water data networks are increasingly being integrated to answer complex scientific questions that often span large geographical areas and cross political borders. Data heterogeneity is a major obstacle that impedes interoperability within and between such networks. It is resolved here for groundwater data at five levels of interoperability, within a Spatial Data Infrastructure architecture. ...

  • Environmental Data Management for Groundwater Contamination

    ESdat environmental data management software has been used to manage and report on large datasets generated from an investigation of groundwater contamination on an industrial facility in Adelaide. ESdat was used in managing site data and the maintenance of conceptual model and time series outputs at a complex site over an extended period. Leakages of TCE and the subsequent ...

  • GroundWater Markup Language (GWML) – enabling groundwater data interoperability in spatial data infrastructures

    Increasing stress on global groundwater resources is leading to new approaches to the management and delivery of groundwater data. These approaches include the deployment of a Spatial Data Infrastructure (SDI) to enable online data interoperability amongst numerous and heterogeneous data sources. Often an important component of an SDI is a global domain schema, which serves as a central structure ...

  • Groundwater and surface water data management at Rosebery Mine, Tasmania - Case Study

    Efficient management of the large monitoring data set is paramount given licence conditions imposed on the mine. Confidence in the data accuracy is crucial in forming the basis for interpretation and subsequent operational decisions. MMG has adopted an Environmental Data Management System (EDMS) comprising the following ‘off-the-shelf’ components produced and supplied by Earth Science ...

  • Groundwater monitoring and assessment with ESdat environmental data management software and its use in groundwater remediation plans

    Groundwater investigations, contaminated/industrial sites, landfill and regulatory compliance are all ideal areas for environmental consultants and site managers, specializing in groundwater monitoring and assessment, to use environmental data management software. A successful groundwater ...

  • Principal Component Analyses of Groundwater Chemistry Data During Enhanced Bioremediation

    Abstract  A bioremediation project has been monitored for two years at a former sour gas plant site that had ethanolamine, glycol and their degradation products in the subsurface. The active enhanced bioremediation program consisted of dewatering and bioventing. An extensive groundwater monitoring program mapped the distribution of chemical species. Principal component analysis was used to ...


  • Making the invisible visible: the impact of federating groundwater data in Victoria, Australia

    The Visualising Victoria's Groundwater (VVG) web portal federates groundwater data for the State of Victoria, Australia, thus making legacy data, government datasets, research data and community-sourced data and observations visible to the public. The portal is innovative because it was developed outside of the government and offers real-time access to remote authoritative databases by ...

System conceptualisation Summary: ESI developed a FEFLOW finite element model of the groundwater system in the ...

  • Soil and groundwater remediation

    At a site in northern Indiana on behalf of a multinational client, Troy Risk operated a groundwater remediation system to cleanup the source of chlorinated solvent impact to a groundwater aquifer system. Prior to 1988, the site was occupied by a manufacturing facility. In March 1995, chlorinated volatile compounds (CVOCs) were detected pursuant to due diligence for real estate refinancing. From ...

  • Groundwater arsenic in Chimaltenango, Guatemala

    In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking water, and sent to the USA for analysis. The only site ...

  • Groundwater Remediation Strategies Tool

    This guide provides strategies for focusing remediation efforts on 1) the change in contaminant mass flux in different subsurface transport compartments (e.g. the vadose zone, smear zone or a zone within an aquifer of interest) and 2) the change in remediation timeframe. In this approach, groundwater flow and contaminant concentration data are combined to estimate the rate of contaminant mass ...

  • Dynamics of nitrate & perchlorate in groundwater.

    The Apache Powder Superfund Site is located in Cochise County, Arizona, approximately 50 miles southeast of Tucson. The site was listed on the National Priorities List pursuant to CERCLA in 1990. Principal groundwater chemicals of concern (COCs) include nitrate-nitrogen (nitrate-N) and perchlorate. Concentrations of nitrate-N exceeding 500 mg/l and 2,300 mg/l have been detected in the “shallow ...

  • The application of groundwater modelling to simulate the behaviour of groundwater resources in the Ramhormooz Aquifer, Iran

    In this study, groundwater modelling was proposed as management tool in Ramhormooz Plain, south western Iran. After definition of a conceptual model, the necessary data were defined into various packages of MODFLOW. Subsequently, the model was calibrated by trial and error estimation and the results were finally optimised by PMWIN through PEST code. After verification process, the model was used ...

  • Potential impact of heterogeneity on groundwater age

    Groundwater age is an important water property used as an indicator of groundwater quality. There have been no sufficient data and measurements underground, and that problem has been mitigated by using direct simulation of groundwater age. This paper has been motivated by the work of Daniel J. Goode, defining a rather different approach. A numerical model has been developed, using the Lagrangian ...

  • Kenya - Groundwater governance case study

    This report presents a case study on groundwater governance in Kenya. The objectives of the study were to: (a) describe groundwater resource and socioeconomic settings for four selected aquifers; (b) describe governance arrangements for groundwater management in Kenya; and (c) identify the relevance of these arrangements for planning and implementing climate change mitigation measures. The report ...

  • Groundwater reclassification for five corners area

    Ralph Penney, president of Penney Engineering, sent a letter in April to Tisbury town officials and property owners around the Five Corners intersection in Vineyard Haven asking for their support for a change in the way the Massachusetts Department of Environmental Protection (DEP) classifies the area's groundwater. Mr. Penney plans to petition the DEP for a change in the area's designation from ...

  • Testing of concrete to determine the effects on groundwater

    The need for a more sustainable construction industry, as well as increasing pressures on landfill space, have led to an increasing use of recycled and secondary materials as aggregates in concrete1,2. However, if users are to have full confidence in these materials, it is important that they are shown to have neither an adverse impact on the properties of concrete, nor on the environment, ...
