Most ESA Standards, including CSA Z-768-01 and the Brownfields regulations in Ontario, require the assessor to identify uncertainties in their ESA, and to consider potential implications to the reported findings and conclusions. While, it is not always feasible to eliminate uncertainty, there are several ways to reduce uncertainty to more manageable levels. Continue reading “Managing Uncertainty”
