Vapor Intrusion
Cracks in foundation
Vapor intrusion is the migration of Volatile Organic Chemicals (VOCs) from groundwater and/or subsurface soil into overlying buildings VOCs: a group of chemicals that easily produce vapors
Sump Pumps Basements/ crawlspace
with dirt floor
Avenues for vapor intrusion

Common Indoor Air Contaminants
> 80%
40 to 60%
In 2011, EPA reviewed 18 indoor air studies from a number of states and found:
Chlorinated Organics: � TCE � PCE � DCE � TCA � Carbon tetrachloride
� Benzene � Ethylbenzene � Toluene � Xylene
• Cigarette smoke, gasoline • Paint thinner, ink • Nail polish • Cleaning products
• Cleaning products • Laundry aids • Aerosols • Paint remover • Refrigeration Fluid
What can you do to improve your indoor air quality?
� Do not buy more chemicals than you need and know what products contain VOCs.
� If you have a garage or a shed, place the properly stored VOC containing chemicals outside and away from your family living areas.
� Immediately clean and ventilate any VOC spill area.

� If you smoke, go outside and/or open the windows to ventilate the second-hand, VOC containing smoke outdoors.
� Occasionally open the windows and doors and ventilate to prevent VOC buildup.
� Consider bringing plants in your home that are shown to help clean indoor air.
