The presentation will focus on lessons learned and insight from experiences with assessing and monitoring natural attenuation mechanisms and long-term performance at megasites with complex groundwater chemistries and heterogeneous subsurface environments.
Multiple lines of evidence are typically used to develop a holistic conceptual site model that considers all four dimensions (time and space), as natural attenuation behavior has been found to change over time and space. This improved understanding of natural attenuation has been used to better predict plume persistence and potential long-term treatment durations, and develop better-informed remedial strategies using cost-benefit analyses.
