  • Mine Dewatering in a Compartmentalized Hydrogeologic Setting at Sishen Mine in South Africa

    Abstract: Sishen mine in South Africa is one of the largest open-pit iron mines in the world. It is characterized by a complex, compartmentalized hydrogeologic setting that comprised numerous dykes, regional water-bearing faults, and inter-bedded localized geologic units. The groundwater flow in the vicinity is mainly controlled by regional dykes and faults in a karst aquifer. A 3-D ...

  • Multiparameter sonde used in combined remedy approach and saves $200,000 in potential costs - Case Study

    A former dry-cleaning site in the Pacific Northwest, Ultra Custom Care Cleaners, was found to be contaminated with PCE (perchloroethylene). According to the U.S. Geological Survey (USGS), PCE was widely used in the dry cleaning of fabrics since the 1940s. PCE is one of the most frequently detected VOCs (volatile organic carbons) in groundwater at a national scale (Moran 2004). PCE is highly ...
