GEO Thermal Remediation: Heating, Extraction, and Treatment

GEO's documented thermal remediation projects combine Gas Thermal Remediation, extraction wells, and aboveground treatment selected for the contaminants and site conditions. GTR uses thermal conduction heater wells to heat affected soil and groundwater while extraction systems collect mobilized contaminants.

Westminster, California: thermal remediation inside a former dry cleaner.

At a former dry cleaner in Westminster, California, GEO installed 17 heater wells, 10 dual-phase extraction wells, and 12 soil vapor extraction wells. The case study reports 108 days of heating and reductions greater than 99% for the identified contaminants in soil and groundwater. Surrounding shops continued operating during treatment.

Monitoring supports treatment control. In the Redwood City case study, thermocouples and a programmable logic controller were used to monitor and control heating. Such instrumentation should not be described as evidence of artificial intelligence unless a specific AI implementation has been documented.

Treatment performance is established through project measurements and confirmation sampling. Results from one site do not guarantee complete contaminant destruction, regulatory closure, or the same outcome at another site.
