Groundwater Restoration: Large‐Scale Benefits of Small‐Scale Processes

Cleaning Up a 3‐Mile‐Long Groundwater Plume: It Can Be Done

“…During this stage, the only contribution to the observed mass flux is back‐diffusion from very low permeability soils, where advection is four to five orders of magnitude slower than in the primary advective pathways. Concentration decline trends represented in Figure will have similar shapes but will have different magnitudes of mass removal achieved the through the phases described above (Suthersan et al ).…”

Three Decades of Solvent Bioremediation: The Evolution from Innovation to Conventional Practice

“…While successful, well fouling management and the need for routine well rehabilitation/reinstallation over the course of injection programs that can extend over 5 years in length provided perspective on the true life‐cycle system requirements to achieve target end points. This awareness, coupled with observations of expedited treatment during recirculation programs has ultimately prompted some pendulum correction toward strictly physical flushing programs (Suthersan et al , ; Suthersan and Potter ) for large, dilute‐plume treatment.…”
