  • Groundwater Well Pilot Boreholes

    Determination of significant hydrogeological properties like effective porosity, clay content, salinity of the pore water and permeability with optimised sets of logging methods in exploration or pilot drillings for ground-water monitoring and supply wells, as well as for projects with interest in mineral water or the use of geothermal energy.

  • Instream Restoration Services

    The health of a river – the resource itself – is a measure of success in addressing erosion and sedimentation issues. When preventive measures are inadequate, and sediment impacts to surface waters continue, it is important to mandate high quality restoration. Traditional attempts at sediment removal, by ...

  • Ejector Dewatering Systems

    Ejector (or eductor) dewatering systems are used to control pore pressures and to lower groundwater levels to provide stable working conditions in excavations. Ejector systems are able to extract groundwater and generate a high vacuum at the base of wells up to 50 m deep and as little as 50 mm in diameter. Vacuum drainage can dramatically improve ...

  • Design of Dewatering Systems

    The purpose of a dewatering system is to control groundwater levels and to reduce pore water pressure in the ground. OGI is able to analyse available geological data and the geometry of a construction site excavation to develop a conceptual model. Using OGI’s experience and knowledge, combined with mathematical modelling techniques, OGI is ...

  • Phase II Environmental Site Assessments

    A Phase II Environmental Site Assessment (Phase II ESA) is an investigation of soil, groundwater, surface water, sediments, and occasionally bedrock or indoor air. The purpose of a Phase II ESA is to evaluate potential source areas of contamination, determine the extent of potential contaminant migration from the source areas, and determine if ...

  • PAH Analysis of Sediment Pore Water (SPME/GCMS-SIM)

    Total PAH concentrations in sediment are generally recognized in the literature to be poor predictors of benthic invertebrate toxicity. Pore water analysis provides a better indication; however, the direct measurement of PAH concentrations in pore water has traditionally been very challenging.

  • Bedrock Remediation

    ERH is a common method of remediation for volatile organic compounds in unconsolidated soils, both above and below the water table. In the past eight years, ERH has been used to successfully treat over a dozen contaminated sedimentary bedrock sites. Sedimentary bedrock treatment has recently expanded to greater depths and into difficult, karst ...
