  • Surface-point resistivity survey case study 1

    Surface-points electrical resistivity surveys area can be used to detect one or several known underground anomalies in timely manner. A minimum of one borehole is needed to carry out Surface-points electrical resistivity surveys. A FlashRES electrical resistivity meter allows users to position active electrodes anywhere they want in the borehole, by conducting the survey in a surface-borehole ...

  • A New Multilevel Ground Water Monitoring System Using Multichannel Tubing

    A new multilevel ground water monitoring system has been developed that uses custom-extruded flexible 1.6-inch (4.1 cm) outside-diameter (O.D.) multichannel HDPE tubing (referred to as Continuous Multichannel Tubing™ or CMT) to monitor as many as seven discrete zones within a single borehole in either unconsolidated sediments or bedrock. Prior to inserting the tubing in the borehole, ports are ...

  • Extraction well design for DNAPL recovery.

    The potential for downward migration of dense nonaqueous phase liquid (DNAPL) into deeper portions of a saturated hydrogeologic unit has important implications for successful groundwater remediation. Little information has been published regarding the design of extraction wells that allow DNAPL recovery without simultaneously creating a conduit for cross contamination by vertical migration ...

  • Network Models in the Control Room the Fact and the Fiction

    In this article Dan Stevens, Senior Support Engineer for Water Distribution Software at Wallingford Software, discusses the potential for Network Models to be used in the control room, what is possible, and indeed what is a sensible level of integration of network modelling with other systems (such as telemetry and SCADA) for a more complete understanding of system operation and performance. For ...

  • REMOVING LIMESCALE IMPROVES WATER QUALITY IN POULTRY FARMS

    Water is one of the most important nutrients in poultry production.  About 70 per cent of a bird’s body is made up of water - eggs contain around 65% water. Birds are constantly losing water in egg production, so there is an obvious need for constant replenishment.  Water intake is almost twice the weight of ...
