Abstract
An integrated soil warming probe assists soil remediation by heating contaminated soil. A thermal probe is driven into the contaminated soil and fluid injected into the soil proximate the thermal probe for enhancing remediation. Such a soil warming probe includes an elongate tube with permeable walls and a conical cap at one end for assisting soil penetration. Circulating tubes within the hollow region of the elongate tube circulate contained fluid therein while providing thermal coupling between the contained fluid to the permeable walls of the elongate tube. The circulating tubes are disposed within the elongate tube so as to leave an independent channel between the circulating tubes and the permeable walls of the elongate tube for channeling a supplemental fluid within and out the permeable walls of the soil warming probe.
