What is in situ steam generation and why is it so important?
ERH makes steam in situ, in all soil types regardless of permeability. This steam acts as a carrier gas to sweep evaporated VOCs toward the vapor recovery wells. In situ steam generation allows ERH to be equally effective in low permeability and heterogeneous soils, and within the vadose zone, perched water, capillary fringe and saturated zones.
