  • Dressing down groundwater contamination

    Unlike the late Paul Newman, who bottled his special-recipe salad dressing and sold it in supermarkets, Dr. Robert Borden simply mixes up his own 'dressing' and pumps it into the ground. That’s because the environmental engineering professor and his graduate students are more interested in feeding microbes to clean up contaminated groundwater than in making just another Ranch dressing. “It’s ...

  • Contamination of groundwater and the risk to human health

    Groundwater is a major source of drinking water in many parts of the world. In industrialised countries, there is increasing concern that groundwater reserves are being contaminated by industrial effluents and the chemical pesticides and fertilizers used in intensive farming. This paper compares some of the existing guidelines for acceptable concentrations of certain common contaminants in ...

  • Remediation Of MTBE Contaminated Soil And Groundwater

    Methyl tertiary-butyl ether (MTBE) is a fuel additive made, in part, from natural gas. Since 1979, it has been used in the United States as an octane enhancing replacement for lead, primarily in midand high-grade gasoline at concentrations as high as 8 percent (by volume). Since the mid-1980s, it has been widely used throughout the country for this purpose. It is also used as a fuel oxygenate at ...

  • 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 Contamination Plume Remediation - Case Study

    19 CMT Multilevel Systems Successfully Installed in Challenging  A facility in Pontypool, Wales, UK was once the location of a plastic forming plant. Over time, chemicals produced through the plastic forming processes were lost into the groundwater beneath the facility, creating a large contaminant plume. Years later it was determined that the plume is ...

  • GCW as a means of efficiently remediating contaminated groundwater

    With the conventional 'Pump & Treat' method, groundwater is normally extracted from one or several wells, cleaned above ground and disposed off to the either groundwater or surface water. Even when extraction and injection wells are combined, predominantly higher perme-able areas are preferentially penetrated and more fine-grained structures are circumflowed. The bulk of contaminants are ...

  • Characterisation of arsenic contamination in groundwater by statistical methods

    Statistical investigation on groundwater arsenic concentration data of southwest Bangladesh was performed. Two data sets of 1998–99 and 2002–03 were selected for this analysis. Summary statistics of the data shows that the mean concentration exceeds the Bangladesh limit (0.05 mg/l) in all areas. Normality of arsenic concentration data was checked by frequency histogram, skewness coefficient and ...

  • Norfolk CC tackle groundwater contamination with low-flow

    Quick and easy access in deep wells Geotech low flow groundwater analysis equipment has enabled quick and easy access to samples at 2m intervals down a 28m screen in deep boreholes. Elizabeth Guilford of Norfolk County Council hired the low flow kit from Geotech and used it on a Norfolk CC landfill where leachate contamination of groundwater was suspected. Samples taken at 2m intervals ...

  • Optimal groundwater contamination monitoring using pumping wells

    This study presents a new method for selecting monitoring wells for optimal evaluation of groundwater quality. The basic approach of this work is motivated by difficulties in interpolating groundwater quality from information collected for only few sampled wells. The well selection relies on other existing data relevant to contaminant distribution in the sampling domain, e.g. predictions of ...
