  • Assessment of geo-hazard potential and site investigations using Resistivity Imaging

    The use of geophysical methods for evaluating subsurface contamination of sites is becoming increasingly popular all over the world. The paper presents the assessment of geo-hazard potential of a site in the City of Duncanville, Texas using Resistivity Imaging (RI). Resistivity Imaging was being used to identify areas of environmental concern and to develop a detailed image of subsurface ...

  • Time lapse resistivity/IP survey case study

    Changes in underground electric resistivity is typically resulted by the variations in groundwater conduction and soil water content. Monitoring this variation will help operator gain a better understanding of the underground water distribution over time.  This may facilitates operators monitor abnormal underground or structural behaviour. Time lapse resistivity survey is ...

  • Multi-electrode resistivity survey for groundwater exploration in the Harare greenstone belt, Zimbabwe

    A multi-electrode resistivity survey, carried out over metasedimentary strata and metavolcanics in the Harare greenstone belt in northeastern Zimbabwe as part of a groundwater resources investigation, illustrates the ability of this technique to produce high-resolution images of the subsurface, which are useful for groundwater resources assessment. The resistivity results provide a clear view of ...

  • Potential soil characteristics for riverbank filtration using 2-D ground resistivity in Kota Lama Kiri, Kuala Kangsar

    Identifying the subsurface profile for riverbank/bed filtration (RBF) using conventional methods such as drilled boreholes is usually labor intensive, costly and acquires only 1-D profiling. Hence, a 2-D ground resistivity method was used as an alternative to obtain a 2-D subsurface profile by extending to 200 m length at Kota Lama Kiri, Kuala Kangsar, Perak site area. Four resistivity survey ...

  • Mineral Exploration in Colombia - Case Study

    Our clients used AGI tools to explore a site of volcanic rocks in order to locate areas of raw material of pozzolan (volcanic ash), which can be mined and sold for profit. Process Our clients used SuperSting R1 for imaging to survey the subsurface of the site in 2D slices in terms of resistivity. They used a Wenner ...

  • Scanning for Leaks & Sinkhole Detection in a Retention Pond - Case Study

    In January 2015, one of our clients used AGI tools and software for leak and sinkhole detection in the liner of a retention pond in Tennessee. Process Our client’s customer had a retention pond that was designed to hold liquid, but it was leaking through a hole in the liner. The client used the ...

  • Archaeological survey 2

    The site of the Meadows’ Wesleyan Cemetery in the Adelaide is thought to contain more than 130 unmarked graves. This site initially had a chapel constructed on it in 1840 and the first burial in 1855.  The initial chapel was replaced by a more substantial stone building in 1856.  Burials continued in this cemetery sporadically until the 1940’s although the site became less ...

  • Fractured Bedrock Remediation - Case Study

    ABSTRACT BOS 200® successfully remediates petroleum groundwater impacts in fractured bedrock at a former truck stop. Based on the post-injection groundwater results from the pilot test and full-scale injection, a No Further Action letter was issued in February 2015. CHALLENGES Over a period of 20 years, site investigation activities revealed a 320 foot ...

  • EPA Technology News & Trends - Tacoma “Well 12A” Superfund Site

    The U.S. EPA Region 10 office uses an adaptive site management approach that relies on high-resolution site characterization (HRSC) techniques for strategic sampling at the Well 12A project area. This approximate one-square-mile project area is one of three at the 2.5-square-mile Commencement Bay-South Tacoma Channel Superfund site in Tacoma, Washington. The vicinity of Well 12A, one of 13 wells ...
