Does ERH dewater the site?
ERH does not dewater the site. Subsurface moisture is required for ERH to work. ERH raises subsurface temperatures to the boiling point of water (100°C or 212°F). Subsurface moisture conducts the electricity between the ERH electrodes. Within the saturated zone, TRS’s net water extraction results in a slight water table drawdown – inches in sandy soils and a foot or two in low permeability clay soils.
