Protecting Building Occupants in Puerto Rico from Vapor Intrusion Hazards
Vapor intrusion occurs when there is a migration of vapor-forming chemicals from a subsurface source into an overlying building. This subsurface source is often contaminated groundwater or soil. These vapor-forming chemicals can cause indoor air quality (IAQ) problems and sometimes pose a health concern for building occupants. Examples of vapor-forming chemicals listed by the U.S. Environmental ...

Protecting Building Occupants from PCBs Once Used in Common Building Materials
Polychlorinated biphenyls (PCBs) were manufactured in the United States from 1929 until their production was banned in 1979. Due to their non-flammability, chemical stability, high boiling point, and electrical insulating properties, PCBs were once used in hundreds of industrial and commercial applications. PCBs are described by the U.S. Environmental Protection Agency (EPA) as belonging to a ...
