  • What is the purpose of soil boring and borehole logging?

    What is the purpose of soil boring? Soil boring is a practice of geotechnical investigations whose purpose is to determine the soils load-bearing capabilities, water table and chemical contamination.  Boring is important because (1) it helps to determine the capacity of the soil to provide support to the structures on the surface, (2) it reveals the permeability of the soil ...

  • Uncertainty Analysis of Mound Monitoring for Recharged Water from Surface Spreading Basins

    This study has conceptually reviewed issues related to implementation of a groundwater mound monitoring well (GMMW) for monitoring recharged water from a surface spreading basin with emphasis on uncertain hydrogeological conditions. For this, we selected a recharge site in the City of Mesa, Arizona, that is characterized with near surface clay lenses of low permeability. A geostatistical ...

  • Chlorofluorocarbon (CFC) remediation case study 2002

    Project Description The project site is located in Northern California and was leased and operated as a chemical storage and solvent recovery operation from late 1972 through April 1993. During an earlier period, the site may also have been used as a waste transfer station. Previous investigations indicate that soil and groundwater at the site, and groundwater down-gradient (westward) from ...

  • Chloroflourocarbon (CFC) remediation case study

    Project Description The Site location was an industrial facility located in the greater South Los Angeles region that manufactured chemicals for local petrochemical and other industrial operations from 1919 through late 1990’s. Refrigerants were initially produced in 1964 including chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) such as trichlorofluoromethane (R-11), ...

  • New advances in planning a bore

    Software helps take out the guesswork Horizontal directional drilling (HDD) is challenging and difficult work fraught with unknown obstacles. While it’s not possible to eliminate every obstacle, bore planning software tools developed by drill manufacturers can help small and large contractors create a bore plan that may help minimize risks. Bore planning software was ...

  • What’s the Temperature? Thermal Modeling and its Importance in Thermal Remediation

    What is a model? A beautiful person who struts down a run way, a scaled down sculpture of the Empire State Building, or a series of equations that describe some phenomenon? Did you guess all of the above? Gold star! Models come in many different shapes and sizes. In the environmental consulting and remediation industry, the word “model” often refers to a numerical model. Numerical ...

  • Determining the circulation depth of thermal springs in the southern Rocky Mountain Trench, south-eastern British Columbia, Canada using geothermometry and borehole temperature logs

    Geochemical data for thermal spring waters along the southern Rocky Mountain Trench in British Columbia, Canada were examined. The range of equilibration temperatures for the thermal springs is between 24 and 59°C, assuming that there is minimal mixing with colder shallow waters that might lead to a lowering of the calculated equilibration temperature. The chalcedony geothermometer is found to be ...

  • Volumetric Analysis & Three-Dimensional Visualization of Industrial Mineral Deposits

    Abstract Base and precious metal deposits are typically characterized by a single parameter such as the total weight of mineable gold. Industrial mineral deposits, on the other hand, are characterized by their end-use. For example, the volumetric evaluation of a limestone deposit depends upon who’s buying the product. The concrete industry has a suite of evaluation parameters such as ...

  • Using the Pencil-Paper Method with a Tablet Computer to Increase Borehole / Well Logging Efficiency

    Traditionally, geologists use pencil and paper when logging soil descriptions, drilling tests, and well diagrams in the field.  We wanted to see if we could speed up this process using a field computer.  We tested a fully ruggedized Yuma2 tablet computer (retail value of $3500) and a consumer grade Dell Venue 8 (retail value $250).  Both computers run a full version of Windows 7 or ...

  • High-Resolution Site Characterization with Multilevel Systems

    Within the last few years, the U.S. EPA added a new focus area on high-resolution site characterization (HRSC) to their Contaminated Site Clean-Up Information (CLU-IN) website. The U.S. EPA’s definition of HRSC is: “High-resolution site characterization (HRSC) strategies and techniques use scale-appropriate ...

  • A GIS-based methodology to delineate aquifer recharge areas

    A GIS-based methodology to delineate risk areas for contamination of groundwater resources is presented by identifying recharge conditions to the aquifer. Identifying the recharge areas is based upon surface and subsurface geologic conditions that may control the risk of potential oil spill contaminants into the aquifer. This study uses the Chicot aquifer system in southwest Louisiana as a pilot ...

  • Integration of Subsurface Data Management and GIS to Facilitate Model Calibration

    Abstract The development of numerical codes, as well as pre- and post-processors to support these codes, has made the discipline of groundwater modelling increasingly more automated and efficient. The value of such modelling is reliant on the site-specific data used to build and calibrate the models. The integration of EarthSoft's EQuISÒ Geology and any of several popular modelling environments ...
