An in-situ thermal remediation method and a drip system for implementing the method. The drip water system collects data and changes its drip operation to optimize performance of the electrode. Electrical current, drip volume, drip cycle time and change in current are measured as a function of time and adjustments are made to the drip water volume and time between injections to optimize performance based on the observed current performance over time. A specialized screen delivers water where it is needed.
A heater for thermal conduction heating suitable for use in non-vertical heater wells for purposes of soil remediation. The heater includes a rigid bar to position a non-insulated heating element in the casing away from the interior surface of the casing.

Thermal conduction heater well and electrical resistance heating electrode
A combination subsurface heating system that incorporates electrical resistance heating and thermal conduction heating with systems disposed within a single borehole. The combination heating system includes an electrically conductive outermost well casing and a heating element that is electrically isolated from the casing but disposed within it or in an adjacent casing but within the same borehole. Each of the two heating components is powered by a separate power source.

A method and system to remediate soil containing PFAS compounds and organic carbon. Total organic carbon is reduced by heating the soil at a sufficient temperature and for a sufficient duration to reduce surface effects between the PFAS compounds and the organic carbon to permit evaporation and treatment of the PFAS compounds from the soil.

Water containing one or more solvents miscible in the water is heated to its boiling point. Air is introduced into the vapor mixture of steam and the miscible solvent at an air-to-steam volumetric ratio that is sufficient to get good transfer of the miscible solvent from the steam to air and provides an equilibrium temperature of the steam-air mixture compatible with operations of the heat exchanger. The mixture of gases is then rapidly cooled to condense the steam into water so that a substantial portion of the miscible solvent remains volatilized in the air. The air and condensed steam fractions are separated.
