    Loon Lake West Shore by Mike Grinnell

    This is a limited observation meant to measure chloride levels in concert with a chloride reduction project with the Ministry of Transportation. My readings indicate how effective the MTO strategies are in trying new methods of chloride reduction. In this instance the MTO is using a DLA method which is the introduction of a brine solution combined with salt crystals. So far, a drop in chloride levels has been observed with the implementation of DLA.
