The intrusion of volatile organic vapors into interior airspace occurs when organic chemicals migrate from contaminated ground water or soil into the airspace of buildings. Some typical organics involved are petroleum based or chlorinated solvents such as TCE, benzene, toluene, and xylene, or oxygenated compounds like MTBE. They may have leaked into the ground water from underground storage tanks, or buried waste, or from disposal in septic systems.   Included in this group are dry-cleaning fluid and deposits from gas stations. Generically, these compounds are Volatile Organic Compounds or “VOCs.”
