    GeoPro Talks – Northern Metals Contamination: Digging Deeper to Evaluate the Risk of Metals Contamination in Soilkeyboard_arrow_down

    The presentation is a case study on an investigation program completed on a large residential development property in a northern community. The investigations required incorporation of some less common techniques for analysis, in order to accurately evaluate risks at the site from elevated metals.The presentation will include an overview of the staged approach used, hurdles that were encountered, and solutions that were implemented to serve the clients needs.

    GeoPro Talks – Chlorinated Solvents – Tips, tricks and tragedieskeyboard_arrow_down

    Investigating chlorinated solvents like they are petroleum hydrocarbons can result in poorly performed investigations, incorrect conclusions, the degradation of site conditions and the potential for increased liability on the consultant.   Given the complex ways chlorinated solvents move in the environment, it is not uncommon for contaminant plumes to be missed and for a consultant to report a contaminated site as clean.  Far worse, certain commonly applied investigation techniques can drive chlorinated solvents into deeper aquifers that were previously uncontaminated.  Thus, the investigation itself can exacerbate the on-site conditions and increase the costs to remediate.This presentation will discuss the key principles that should be used during the development of a chlorinated solvent investigation strategy.  The principles discussed will include, drilling methodologies, the placement of monitoring points, the depths of samples, the environmental media sampled, and the materials used to construct groundwater wells.  Differences between the principles applicable in a hydrocarbon investigation and a chlorinated solvent investigation will be highlighted, with an explanation of the science behind these differences.

    GeoPro Talks – Radon Awarenesskeyboard_arrow_down

    Radon is a radioactive gas that occurs naturally when the uranium in soil and rock breaks down. It is invisible, odourless and tasteless. The gas moves through the ground and can enter buildings, with the potential to accumulate to levels which pose a risk to the building occupants health. Because there are so many factors, it is not possible to predict the radon level in a building. Therefore, only way to know for sure is to test and the only way to reduce the levels is through mitigation.

    GeoPro Talks – In situ Salt Remediation of Soilkeyboard_arrow_down

    The choices for remediating salt contaminated soil are limited. Often, excavating contaminated soil and placing it into a landfill facility is the only option. Depending on location and the amount of contamination, this is not always practical or economically viable.The presentation will review some of the options available for in situ remediation of salts in soil, including a look at case studies involving Earthmaster’s PEPSystems® bacteria/plant technology as a sustainable method for treating contaminated soil and conserve it. The economics of using various methods to treat soil will be discussed along with the carbon benefits of leaving soil in place and treating it.
