  • Blending as the best compliance option for the management of radioactivity in drinking water supplied from the deep sandstone aquifer in Southern Jordan

    This paper describes management options and interventions taken by the Government of Jordan to ensure that the quality of drinking water supplied to consumers via the Disi Water Conveyance Project (DWCP) meets Jordanian drinking water standards and WHO guidelines for drinking water quality in respect of their radiological composition. Results from an initial survey of radioactivity present in ...

  • Biotic and abiotic anaerobic transformations of trichloroethene and cis-1,2-dichloroethene in fractured sandstone

    A fractured sandstone aquifer at an industrial site in southern California is contaminated with trichloroethene (TCE) and cis- 1,2-dichloroethene (cis-DCE) to depths in excess of 244 m. Field monitoring data suggest thatTCEis undergoing reduction to cis- DCE and that additional attenuation is occurring. However, vinyl chloride (VC)andethenehavenotbeendetected in significant amounts, so that if ...

  • Geological barrier--a natural rock stratus for preventing confined karst water from flowing into mines in North China

    Abstract Coalfields in North China encompassing more than ten Provinces contain six to seven coal seams in the Permo-Carboniferous strata. The lower three seams, accounting for 37% of the total reserves, are threatened with karst water from the underlain Ordovician limestone. Hundreds of water inrush incidences have occurred in which a large amount of water suddenly flows into tunnels or working ...

  • EHC® plume treatment for TCE and daughters, installed in 2008

    The Meteor Park Development, formerly the Delta Metals engineering facility (Figure 1), lies close to Birmingham city centre. In the years prior to 2006, development had been marginal due to spiraling remediation costs associated with significant impacts to site groundwater and soil. The lead consultant and remediation contractor (WSP Remediation Ltd.) adopted a combination of sustainable on-site ...


  • Groundwater, flooding and hydrological functioning in the Findhorn floodplain, Scotland

    A large floodplain of the River Findhorn, northeast Scotland, was investigated using hydrogeological and hydrochemical methods (including residence time indicators) to characterise groundwater/surface-water coupling and groundwater flooding. The study demonstrated widespread stratification within the floodplain: shallow (<8 mbgl) deposits are highly permeable (100 m/d); deeper deposits ...

  • Managanese study: Severn Trent

    Severn Trent Water operates a number of boreholes which abstract water from the underlying Sherwood Sandstone aquifer in the West Midlands.  Prior to 2000, manganese concentrations at one of these sources were reported to be <5µg/l but by 2002 were found to be significantly higher than this.  This posed a possible threat to the source.  Further sampling in 2007 suggested ...

  • Human health risk assessment of an arsenic contaminated golf course

    St Michael’s Jubilee Golf Course in Widnes was constructed between 1964 and 1986, by re-grading chemical waste deposits generated from local industries, which were then covered with a thin layer of topsoil and grassed over.  An estimated 4.5 million tonnes of waste materials are present beneath the golf course.  The site is underlain by alluvium and a major aquifer, the Sherwood ...

  • Trends, prospects and challenges in quantifying flow and transport through fractured rocks

    Among the current problems that hydrogeologists face, perhaps there is none as challenging as the characterization of fractured rock (Faybishenko and Benson 2000). This paper discusses issues associated with the quantification of flow and transport through fractured rocks on scales not exceeding those typically associated with single- and multi-well pressure (or flow) and tracer tests. As much of ...

  • Carbon capture could be costly and risky

    There’s bad news for those who think that carbon dioxide can be removed from the atmosphere and stored deep in the Earth’s rocks. Even if carbon capture is possible, sequestration in the rocks is fraught because the gas can find multiple ways to escape, according to a report by a team from Penn State University, US, in the International Journal of Greenhouse Gas Control. Back in the ...

  • Eco-Hydrology

    The Habitats Directive and the Environment Agency’s Restoring Sustainable Abstraction programme (RSAp) have focused attention on a large number of wetland sites across the country. Some of these are large, high profile sites that have been subject to many detailed studies in the past. However, many sites have had little work carried out on them and the behaviour of their hydrological ...

  • Refinery remediation: fuel recovery and recycling

    Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

  • Run cars on green electricity, not natural gas

    With the dramatic increase in oil prices earlier this year translating into higher prices at the gas pump in the United States, concerns over US dependence on foreign oil are once again part of the national discussion on energy security. Combined with the growing understanding that carbon emissions from the combustion of fossil fuels are driving global climate change, the debate is now focused on ...

    Multilevel well network provided high-density data at a reduced cost CHALLENGE After installing a number of traditional  monitoring wells at the site, it became  clear to the project scientists that more  and better data would be necessary  to properly characterize the complex  groundwater flow system. SOLUTION ...


  • Can we bury the carbon dioxide problem?

    Seriously — carbon capture and storage could be a game-changer. Mention “carbon capture and storage” — the process of trapping carbon dioxide produced in fossil-fuel burning or other industrial processes and burying it underground — in polite company, and you’re likely to be pounced on. It’s absurdly expensive. It can never be rolled ...
