Its great to see the City of Guelph cleaning up a contaminated site found last September. It looks like a standard soil excavation dig and dump. No mention of a consultant being involved however the article notes some pretty good due diligence during the remediation (geophysical survey, dust control plan, ground and surface water management plan, spill response and contingency, etc.). http://www.thefountainpen.com/s/showstory?id=13971
