  • DOD evaluates bioaugmentation for remediating low-pH aquifers

    The US Department of Defense (DOD) has completed pilot-scale work on the 'MAG-1' site at Fort Dix, NJ, to test suitability of anaerobic bioremediation for an aquifer with low pH. Project results will be used to design full-scale ground-water treatment at MAG-1. In addition, technical criteria gained from the demonstration will be integrated into DOD’s remediation strategy for its many facilities ...

  • Combined interpretation of radar, hydraulic, and tracer data from a fractured-rock aquifer near Mirror Lake, New Hampshire, USA

    An integrated interpretation of field experimental cross-hole radar, tracer, and hydraulic data demonstrates the value of combining time-lapse geophysical monitoring with conventional hydrologic measurements for improved characterization of a fractured-rock aquifer. Time-lapse difference-attenuation radar tomography was conducted during saline tracer experiments at the US Geological Survey ...

  • 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 ...

  • Technical protocol for evaluating natural attenuation of chlorinated solvents in ground water

    The U.S. Environmental Protection Agency is charged by Congress with protecting the Nation’s land, air, and water resources. Under a mandate of national environmental laws, the Agency strives to formulate and implement actions leading to a compatible balance between human activities and the ability of natural systems to support and nurture life. To meet these mandates, EPA’s research ...

  • Case study - Westbay System reduces construction costs by 65%

    Multilevel monitoring network delivers unprecedented definition of groundwater flow and water quality at a reduced cost CHALLENGE OCWD had determined that information  on the piezometric level and water quality  of each aquifer layer was required to  optimize management of the recharge,  storage, and recovery of groundwater. ...


  • Water Level Measurements-Part 1

    Confused about which instrumentation to use in your water level monitoring system? In-Situ offers two categories of pressure sensors for water level measurements: absolute or non-vented sensors, and gauged or vented sensors. They look the same and both measure pressure and water level, but they have drastically different applications, outputs and accuracy. The absolute (or non-vented) water level ...

  • Case study: URS - Identifying remediation locations saved hundreds of thousands

    One of the biggest threats to public health today is unsafe water. A billion people across the world don’t have access to clean drinking water, in part because many subsurface aquifers have been poisoned. Perhaps the most famous example of this was the Love Canal crisis of 1978. The Niagara Falls neighborhood experienced high rates of cancer, birth defects and other sicknesses due to ...

  • Case study - Westbay System Data improved understanding of groundwater conditions in geologic repository

    Multilevel well system delivered accurate measurements of hydraulic properties CHALLENGE One of the major challenges facing  ANDRA during the initial stages of  construction was to monitor the effects of  construction on the geological formations  overlying the argillite. SOLUTION To monitor changes in ...
