In-Situ Thermal Remediation
This course provides guidance and background for the appropriate screening and selection of in situ thermal remediation (ISTR) technologies, including steam enhanced extraction injection, electrical resistivity heating, and thermal conductive heating. It is intended to help distinguish proper applications of the technology and identify important design, operational, and monitoring issues relevant to hazardous waste sites.
A significant number of sites are contaminated with high levels of organic contaminants, including chlorinated solvents, oils and petroleum products, polychlorinated biphenyls, and wood-preserving compounds above and below the water table. Many of these sites are known or suspected to contain non-aqueous phase liquids (NAPL), either as mobile or residual immiscible fluids. Some of these compounds have low volatility and solubility. These contaminants, especially NAPL below the water table, have been difficult to treat with conventional technologies such as groundwater extraction, bioremediation, and soil vapor extraction. NAPL often represents a very significant long-term (decades to centuries) source of dissolved phase contaminants. More aggressive technologies have been sought that would address these conditions. These aggressive technologies include in situ chemical oxidation, surfactant/solvent flushing, and ISTR methods. The ISTR methods represent the most aggressive and effective of these techniques.
Once you complete your course review, you need to take a multiple-choice quiz consisting of sixty (60) questions to earn 12 PDH credit.
