The equipment used in thermal soil remediation has been used successfully in processes with similar technology. This type of equipment has proven to be environmentally responsible and capable of meeting strict emission standards. In thermal soil remediation, a rotary drum is used to heat the soil. A baghouse is the air pollution control mechanism used to minimize soot, dust and lead emissions. Rotary drums and baghouses are used effectively in the asphalt business.
Afterburners are a proven technology for control of organic compound emissions.
The implementation of state and federal regulations requiring identification and excavation of leaking underground storage tanks has resulted in a drastic increase in reports of petroleum contaminated soil and ground water. In 1990, at least 85,000 sites nationwide were contaminated by leaking underground tanks. That contaminated soil has been disposed in solid waste landfills for decades. We've been filling up our landfills with dirt that poses a threat to ground water. Clearly, a more responsible solution was overdue.
