  • 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 ...

  • Multiple location integrated management plan case study

    A multiple location restaurant chain was challenged by increasing costs from their waste hauler and a lack of response regarding service concerns and pricing questions. The RecycleSmart Solution RecycleSmart worked with the existing service provider to complete a full inventory of all locations, right sizing of waste bins for each location and developing schedules to fit the ...

  • Scanning proposed borehole locations for Utilities case study

    Environmental and engineering firms often are tasked with performing soil borings for monitor well installation as part of a Phase II Environmental Site Assessment. This task becomes more challenging when the borings are to be installed in gasoline stations, right of ways or other areas where there are numerous underground utilities that are either unmarked or not properly located. GeoView can ...

  • A case study of some lakes located at and around Thane City of Maharashtra, India, with special reference to physico-chemical properties and heavy metal content of lake water

    The increasing trend in concentration of metals in the environment has created considerable attention amongst ecologists globally during the last decades. However, no such studies have been carried out in India and there are no past metal load data available. Therefore, we initiated a study to estimate the levels of water pollution of the Upavan, Masunda, Makhmali and Rewale Lakes situated at ...

  • Asbestos exposure and your job: at-risk occupations, industries and locations

    Exposure to asbestos fibers can cause asbestos-related diseases including mesothelioma cancer and others. A potentially dangerous exposure can result from very small fibers at low exposure levels. Most such exposure would likely have occurred prior to the 1980s, but the latency period can be up to 40 years for most asbestos-related cancers to develop. Many people have come into contact with ...
