The Triad offers a whole new toolbox for approaching decision-making and associated data collection efforts during hazardous waste site characterization and remediation. The use of a Triad approach will likely include standard techniques to some degree as appropriate, but will do this within the overall goal of managing decision-uncertainty so that decisions can be made with acceptable levels of confidence. Although many of the individual project activities are the same or very similar as before, the order in which they are performed may be different under the Triad.
