Successful cleanup actions or monitoring depends on an accurate CSM. A CSM is any tool(s) that lets you represent, "conceptualize" or "model" site contamination issues and concentration populations so you can make predictions about nature, extent, risk, and risk reduction strategies. The Triad approach is a framework to build accurate CSMs “faster, cheaper, and better” than before possible by using modern technologies to support highly efficient work strategies. Two examples of these technologies are presented.
