A system for mitigating the flow of vapors from contaminated soil into a building has a blower pulling an exhaust from underneath the sub slab of the building and blowing the vapors away from the building. The blower is controlled by pressure sensors that measure the pressure drop across the sub slab. The sensors are monitored to make sure they all have a minimum pressure drop. If any of the sensors has an inadequate pressure drop, the blower speed is increased by a small amount. If all of the sensors have adequate pressure drop, then the blower speed is decreased by a small amount. The system then rechecks the pressure drops on a periodic basis and makes appropriate blower speed adjustments after each measurement.
