ENVIRONMENTAL TESTING includes testing for such environmental hazards as Carbon Monoxide (CO), Lead in paint, mold, pests such as termites and carpenter ants, radon in air or water, and water testing for adequate supply and for organic or inorganic compounds.  
CARBON MONOXIDE (CO)
Carbon monoxide is a colorless, odorless gas that is produced as a result of incomplete combustion of burning carbon-containing fuels. Exposure to CO reduces the body's ability to carry oxygen. Carbon monoxide exposure affects everyone, but especially unborn babies, infants, and people with anemia or a history of heart or respiratory disease.

Main areas of concern are leaks to living space from garage areas, portable heaters, and poorly adjusted furnaces. Carbon monoxide is tested by taking samples of air for analysis.

LEAD IN PAINT
Homes built before 1978 are likely to contain lead-based paint which can be a health hazard especially for children. Normally, it is found as dust around windows, door frames, and stairways. The main concern is that peeling and chipping paint and dust can be consumed by children causing developmental problems.

The materials in question need to be tested either with a swab-type test, by sending samples to an EPA approved lab, or by an x-ray machine.

MOLD
Mold and fungus grow naturally indoors and can get into a house through almost any opening or by attaching themselves to people or pets. Mold and mildew generally appear as a result of moisture from a shower or lavatory but can also appear from other sources of moisture such a leaking water supply lines or leaking roofs. Materials such as wood, plywood, carpet, and drywall can provide the necessary food source which molds need to grow. Coupled with a source of moisture, these materials can facilitate mold growth.

Testing for mold involves sending samples to an approved laboratory for analysis.

PESTS
A pest inspection can be conducted for wood destroying organisms such as carpenter ants, termites, powder post beetles, mold, and fungus. This inspection also includes rodents, squirels, birds and other pests that are present. The pest inspection is included with a building inspection.

RADON IN AIR
Radon is an odorless and colorless radioactive gas that forms during the decay of radium which can be found naturally in some soil or bedrock. It is a health hazard because prolonged exposure can lead to an increased risk of lung cancer. It is measured in picocuries per liter (pCi/L). The recommended action level is an annual average of 4 pCi/L or more.

Testing is done by sampling air over a period of time, usually 48 hours in "closed house conditions." This means that all windows and doors are closed 12 hours prior to the test. Also no air conditioners, fans or other devices that exchange outside air can be run during the test. Normal door entry is allowed but are not to remain open during the test.

Treatment for homes with high levels of radon can be done by a professional using a system of venting radon to the outside in conjunction with fans.

WATER
Water is generally tested for bacterial and other organic compounds to determine if it is safe to drink. Testing for inorganic compounds is also done to determine the usability of the water such as "hardness." Samples are sent to approved laboratories for analysis.

Well flow tests can also be performed to determine the adequacy of the water supply for the intended use of the occupants.

NOTE: The most significant problems of a home are caused by water penetration which causes rot and supports wood destroying pests and molds.
