  • 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 ...

  • Radon distribution in groundwater of Taiwan

    Radon levels were surveyed in 517 monitoring wells constructed in five major groundwater areas of Taiwan. The radon concentration in groundwater samples varied in a wide range from below the detection limit of 18 pCi/L up to 1,100 pCi/L. A worldwide comparison of reported groundwater radon levels was conducted. Overall radon levels in Taiwan groundwater are relatively low compared to other ...

  • Groundwater arsenic in Chimaltenango, Guatemala

    In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking water, and sent to the USA for analysis. The only site ...

  • Dynamics of nitrate & perchlorate in groundwater.

    The Apache Powder Superfund Site is located in Cochise County, Arizona, approximately 50 miles southeast of Tucson. The site was listed on the National Priorities List pursuant to CERCLA in 1990. Principal groundwater chemicals of concern (COCs) include nitrate-nitrogen (nitrate-N) and perchlorate. Concentrations of nitrate-N exceeding 500 mg/l and 2,300 mg/l have been detected in the “shallow ...

  • 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 ...

  • Crosshole resistivity survey case study 2

    Crosshole resistivity survey to search out industrial waste water This exploration survey used the crosshole resistivity technique to observe whether or not an industrial waste water plant is leaking. Chemical analyses found that this specific waste water has a low resistivity compare to normal groundwater. Our recent example shows at depth of 45m a comparatively high resistive zone fabricated ...

  • GPR survey to locate USTs and piping at a retail facility

    PROJECT: GPR survey with confirmatory drilling + soil and water sampling / analysis LOCATION: Spokane, Washington PROJECT DESCRIPTION: Designed and performed a tight-line / saturation Ground Penetrating Radar (GPR) survey of an active retail property, to determine the presence, if any, of buried 1950s-vintage underground storage tanks (USTs). Performed ...

  • Crosshole resistivity survey case study 1

    Crosshole resistivity survey to find water Crosshole survey can be very effective in detecting groundwater and fracture zone. In some case, even with environmental limitation, where only a handful electrodes can be depolyed, crosshole resistiviy survey can still produce sound result. For example, in one of the survey we did, seven and fourteen electrodes were employed in the left and ...

  • Willowstick surveys are applicable and affordable on small projects

    Over the course of Willowstick's eight-year history, we have had the opportunity to work with many prominent clients on large, complex projects. As a result of this, many potential clients have had the perception that Willowstick is "expensive" and not suitable for smaller, less complex projects. While it is generally true that Willowstick's rates might not cost the same as more traditional ...
