Vapor mitigation system, vapor mitigation controller and methods of controlling, monitoring and mitigating vapors

A vapor management system, comprising:

• a monitoring service system configured to:
• i) communicate with at least one vapor mitigation system, ii) monitor a contaminant concentration in a region beneath a building, and iii) monitor and adjust one or more system parameters of an operational state of the at least one vapor mitigation system during a continuous operational state of the vapor mitigation system, the one or more system parameters comprising one or more of:
• airflow set point, vacuum set point, or blower current set point,
• wherein the monitoring service system is further configured to generate a user interface, the user interface configured to display and permit adjustment of the one or more system parameters during the continuous operational state of the vapor mitigation system in a close-loop configuration to maintain i) a pressure differential between an interior area of the building and the region beneath the building and ii) a volumetric flow of soil gases from the region beneath the building so that an exhaust contaminant concentration does not exceed a predetermined exhaust contaminant concentration, by monitoring directional air flow in the at least one vapor mitigation system and dynamically limiting the directional flow of air between outside the building and the region beneath the building.
