Abstract
Heated hydrogen peroxide reagent under pressure is supplied to a well for underground remediation of pollution; the reaction with the pollutant is exothermic so that the high temperature of the reagent when injected is maintained as the reagent spreads. The remediation reaction is monitored by sensors, to regulate the supply of reagent and to shut off the supply automatically when the pollutant has been reduced to an acceptable level.
