  • Response of rock-fissure seepage to snowmelt in Mount Taihang slope-catchment, North China

    The complex physiographic and hydrogeological systems of mountain terrains facilitate intense rock-fissure seepages and multi-functional ecological interactions. As mountain eco-hydrological terrains are the common water sources of river basins across the globe, it is critical to build sufficient understanding into the hydrological processes in this unique ecosystem. This study analyzes ...

  • Studies on Microbial Heavy Metal Retention from Uranium Mine Drainage Water with Special Emphasis on Rare Earth Elements

    Microbial heavy metal retention was studied using seepage water sampled from a former uranium mining site in Eastern Thuringia, Germany. The seepage water has a low pH and contains high concentrations of metals, including uranium, rare earth elements (REE), and other heavy metals. Microbial influence on sorption and/or active uptake of heavy metals was studied using REE patterns. Incubation of ...

  • Investigating the permeability of fractured rock masses and the origin of water in a mine tunnel in Shandong Province, China

    The coastal Sanshandao mine is threatened by the overlying Quaternary water and seawater. Following an introduction to the geology and hydrogeological conditions in the mine area, a detailed hydrogeological survey and sampling were conducted and hydrochemical and stable isotopic (δ2H and δ18O) tests on various waters were carried out to characterize the origin of water in the mine ...

  • A cost-effective method to protect the coastal regions from sea level rise. A case study: northern coasts of Egypt

    Sea level rise resulting from climate change represents one of the major challenges for coastal regions, e.g., coastal erosion, submergence of shore cities and saltwater intrusion. This study presents a feasibility study of using a diaphragm wall (DW) to protect the northern coasts of Egypt from sea level rise. The study includes assessment of environmental and socio-economic impacts of the ...

  • Open Pit Modeling

    The Problem Open pits are a common method of mining in the world. The design of such pits requires the application of technologies from a number of fields. One of the common scenarios is that the bottom of the pit may possibly extend beneath the water table of the surrounding geo-strata. If this is the case then a suitable set of pumping wells must be designed in order to ensure that ...

  • Using Geosynthetics in Slope Stability

    The majority of slope failures within the geosynthetics industry can often be avoided with proper engineering and material selection. However, the factors that affect slope stability can be difficult to discern and measure. Soil thickness, seepage forces, seismic forces, gas uplift, geomembrane texturing, engineering and provision of reinforcing elements are only a few of the factors affecting ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...


  • High pressure pumping systems - it`s all in the design

    High pressure pumping systems are used in a wide range of industrial processes. Careful selection of the components of the pumping system is essential for optimum safety and reliability. Failure to install a quality pump designed for the task could present a potential risk to human health or life or result in significant down-time and loss of production capacity with the associated costs to the ...

  • Co-Metabolic Processes

    Introduction: Co-metabolism is one form of secondary substrate transformation in which enzymes produced for primary substrate oxidation are capable of degrading the secondary substrate fortuitously, even though the secondary substrates do not afford sufficient energy to sustain the microbial population. An emerging application involves the injection of water containing dissolved primary ...

  • The Future of Drinking Water

    Predicted future growth in population numbers and rising sea levels mean demand for drinking water will continue to increase just as the natural availability of freshwater decreases. It is likely that brackish groundwater will be an important source of drinking water in the future, but the current methods used to produce fresh water from this source are expensive in terms of their energy use and ...

  • Consideration of the Effects of Remediation Technologies on Natural Attenuation.

    ABSTRACT: We have long understood and continue to improve our understanding of the geochemical conditions that favor biodegradation of petroleum hydrocarbons. Over the last several years our understanding of the conditions that are necessary for and/or promote reductive dechlorination of chlorinated hydrocarbons has improved substantially. Over this time in situ remediation technologies have ...
