  • Geophysical applications to solid waste analysis

    Abstract: Case studies of regional landfills show that electromagnetic geophysical methods can accurately and inexpensively define boundaries and thickness of waste. Degradation of putrescible solid waste generates conductive leachate that can be imaged with a frequency-domain terrain conductivity meter. Terrain conductivity measurements can be modified through a simple algorithm based upon ...

  • Non-intrusive site investigation (UXO, CWM concerns)

    BEACON personnel used global positioning system (GPS) equipment to map out site locations. The soil-gas data clearly identified source areas of Trichloroethene (TCE) as well as other compounds of concern. The results showed the location of chlorinated contamination, which correlated well with data from a geophysical survey. While the flux chambers were in the field, more than nine inches of rain ...

  • A combined mathematical geophysical model for prediction of pyrite oxidation and pollutant leaching associated with a coal washing waste dump

    The waste produced by coal washing process produces many environmental problems. In this study, the pollution problems associated with the waste produced by Alborz Sharghi Coal Washing Plant was investigated by mathematical modeling. The study area is located at 11 km. to Razmjah coal region and 45 km. to Tehran-Mashhad road in ...

  • Methods used to carry out six roadway investigations of sinkholes

    Abstract Karst conditions are a prevalent problem impacting many roads, bridges and highways of the United States. Six case-histories present an overview of investigations made to determine the presence of karst (sinkholes and cavities) and their possible impact on existing or new construction. These six case-histories represent projects which range from reconnaissance investigations to ...
