  • Modelling of coastal hydrogeology of Krishna delta in India

    Numerical techniques are widely used for modelling groundwater aquifers. Hydrological models are generally concept based and highly non-linear due to complex parameterisation as compared to models of other disciplines. Calibration and validation of such models cannot follow conventional methods borrowed from other disciplines many times due to scale of the model domain. In the present paper, ...

  • The karez of the Sauran region of Central Asia

    A large number of lines of water collection wells were identified by aerial surveys in the arid region near the ancient city of Sauran on the Middle Syr Darya (South Kazakhstan, Central Asia). They are locally called karez, which in Persian means ‘water uplift’. Initially these were assumed to be qanat, a water collection and distribution system that is widespread in the Middle East, North Africa ...

  • Landfill site characterisation at Kham Bon village, Muang district, Khon Kaen province, NE Thailand

    The aim of the study is to characterise the Kham Bon landfill site. Hydrogeological and geochemical surveys were conducted and four boreholes were drilled. The hydraulic properties of the aquifer were tested, and soil, surface water and groundwater samples were collected at various times in the year. The physical and chemical properties of the samples, especially heavy metals, were analysed. The ...

  • Managing RCRA statistical requirements to minimize ground water monitoring costs

    Abstract This paper will provide an overview of how ground water monitoring statistical choices can significantly impact a facility's ground water monitoring costs. For example, a recent study analyzed the long term ground-water monitoring cost impacts of different statistical analysis approaches on over 20 landfills. The study found that the choice of statistical approach can make over a ...

  • 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 ...

  • Spolchemie site remediation and NanoRem field site application

    Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the ...
