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 ...

Gypsum: Isotopes & Dating
Gypsum is a relatively soft and common mineral made up of hydrous calcium sulfate (CaSO4-2H2O). Whilst pure gypsum crystals are transparent (often with a pearly or vitreous luster), they can appear opaque and colored due to the inclusion of other materials (e.g. sand). It often forms in evaporative sedimentary environments and is commonly found intact floating within other carbonate and/or ...

Vapor Intrusion Hazards and Resources to Protect Building Occupants
The New York State Department of Environmental Conservation describes vapor intrusion as the process by which volatile chemicals move from a subsurface source into the indoor air of an overlying or adjacent building. They share the fact that the subsurface source can either be contaminated groundwater or contaminated soil which releases vapors into the pore spaces in the soil. Vapors can also ...
