  • Geodrilling International - Installation of Closed-loop Borehole Probes

    The installation of closed-loop borehole probes is a challenge on almost any project. With many domestic clients requiring a large meterage of borehole to be installed in a small site, Nicholls Boreholes has found that the traditional manual installation of closed-loop borehole probes is no longer a safe or acceptable option. The company has developed the Loop Feeder, a hydraulically-driven, ...

  • Waterquality in irrigation canals and boreholes - Greece

    Background Kavala is located in the North East of Greece, 680 km from the capital Athens. The population of the prefecture of Kavala is around 85,000 people. The River Nestos which flows through this prefecture is very important for the agriculture of the area. To allow for a fair distribution of the water for irrigation purposes, a number of Boreholes and canals have been established. The ...

  • Pressuremeter Creep Testing in Ice: Calibration and Test Procedures

    In situ pressuremeter creep tests of ice require that particular attention be paid to the precision with which the borehole diameter is measured because failure of ice often occurs at strains as small as 1%. Therefore, precision is important to obtain an accurate picture of the stress-strain-time response of the ice before failure. Also, the pressure applied to the ice must be known precisely ...

  • EPA studies identify techniques for critical leak testing prior to soil-vapor sampling

    Researchers at EPA’s National Risk Management Research Laboratory (NRMRL) in Ada, OK, are developing quality assurance (QA) measures for soil-gas and sub-slab sampling methods that help differentiate contaminant vapors due to vapor intrusion from background sources. Recent research focused on measures to identify leakage of ambient air into conventional vapor probes, which can significantly ...

  • Measuring Static Water Levels Made Easier with Eno Scientific

    The Well Sounder 2010 PRO is a sonic water level meter, designed and manufactured by Eno Scientific, to measure static water level in wells, piezometers or boreholes. This portable handheld unit uses sound waves to measure the distance from the top of the well to the water level. This eliminates the need to lower anything into the well. Unlike standard water level tapes these acoustic meters are ...

  • Using distributed temperature sensors to monitor an Antarctic ice shelf and sub-ice-shelf cavity

    ABSTRACT. Monitoring of ice-shelf and sub-ice-shelf ocean temperatures represents an important component in understanding ice-sheet stability. Continuous monitoring is challenging due to difficult surface access, difficulties in penetrating the ice shelf, and the need for long-term operation of non-recoverable sensors. We aim to develop rapid lightweight drilling and near-continuous fiber-optic ...

  • Case study - Remote water quality monitoring in South Africa

    Situated in the Mpumalanga province of South Africa, the Xstrata Coal South Africa (XCSA) runs several open cut and underground mining operations producing thermal coal. To ensure their mining operations do not affect the surrounding natural water bodies, the company employs Hydrolab and OTT water quality monitoring equipment with remote data transmission options: the OTT ecoLog 800 water level ...
