Environmental Issues
It seems that we hear a lot about environmental concerns these days. Much of it is simply the result of a greater awareness than in the past. And even though there isn?t anything to be concerned with in most homes, there are still a number of potential home environmental issues that buyers should be aware of.
Water quality is probably the most common concern and the one most often tested for. Typically, a basic water quality test will check pH, water hardness, the presence of fluoride, sodium, iron and manganese, plus bacteria such as E-coli. Additionally, water may be tested for the presence of lead or arsenic.
In homes built before 1978, lead based paint may be present. Generally, if the lead based paint is in good condition, not cracking or peeling, it is not a hazard. If the condition is hazardous, the paint will either need to be removed or sealed in such a manner as to eliminate the hazard.
Another common environmental concern with the home is radon. Radon is a radioactive gas that comes from the natural decay of uranium in the soil. Pretty much all homes have some radon present, tests can determine if the level present is higher than what is considered safe. If the level is too high, a radon reduction system will need to be installed.
In older homes built more than 30 years ago, asbestos was used in many types of insulation and other building materials. If the asbestos is releasing fibers into the air, it needs to be removed or repaired by a professional contractor specializing in asbestos cleanup. But, if the asbestos material is in good repair, and not releasing fibers, it poses no hazard and can be left alone.
Radon Information
There are cracks in the foundation. Nothing structural. Nothing that?s going to threaten the stability of the home, but they?re there. Nooks, crannies and holes through which seeps an invisible threat. Colorless, odorless and undetectable by your average human, it is none the less the second leading cause of lung cancer in the United States.
Radon gas - even the name sounds ominous, evoking images of radiation and nuclear devastation ? is created when uranium in the soil decays. The gas then seeps through any access point into a home. Common entry points are cracks in the foundation, poorly sealed pipes, drainage or any other loose point. Once in the home, the gas can collect in certain areas ? especially basements and other low-lying, closed areas ? and build up over time to dangerous levels. The Environmental Protection Agency of the US Government has set a threshold of 4 pico curies per liter as the safe level. As humans are exposed to the gas over a period of years, it can have a significant and detrimental effect.
How widespread is the problem? Radon has been found in homes in all 50 states. Certain areas are more susceptible than others (http://www.epa.gov/radon/zonemap.html), but no location is immune. Concentrations of radon-causing materials in the soil can be either natural or man-made. Homes built near historic mining operations may be at higher risk. The only way to tell for sure is to have a home tested.
Testing for radon comes in two forms: active and passive. Active devises constantly measure the levels of radon in a portion of the home and display those results. Passive devices collect samples over a period of time and then are taken away and analyzed. Either method can help you determine your level of risk. Do-it-yourself kits are available from a number of outlets, normally with passive devices. Over a period of days, the device is left in the lowest level of the home which is normally occupied. This eliminates crawl spaces under the house, but includes finished or unfinished basements. Then the results are analyzed by a professional. The other option is to engage a qualified professional to conduct the tests properly. The EPA web site (http://www.epa.gov/radon/manufact.htm) provides information on finding an appropriate resources and testing devices.
If high concentrations of radon are found in your home, you have several options. Since radon is only a problem when it is concentrated in high volume, improving the ventilation in an area is often sufficient to solve the problem. In other cases, it may be necessary to limit the amount of radon getting into the home by sealing or otherwise obstructing the access points. Once again, a professional should be engaged to ensure that the radon is effectively blocked. Typical radon mitigation systems can cost between $800 and $2500, according to the EPA.
If you?re buying or selling a home, radon can be a significant issue. Buyers should be aware of the radon risk in their area and determine whether a radon test is desirable. When in doubt, the EPA always recommends testing. The cost of the test can be built into the house price. If test results already exist, make sure they are recent or that the home has not been significantly renovated since the test was performed. If in doubt, get a new test done. If you?re selling a home, having a recent radon test is a great idea. By being proactive, you can assure potential buyers that there is no risk and avoid the issue from the start.
So whether you have an old home or a new one, live in an old mining town or in the middle of the Great Plains, radon is a reality. But it is a reality that we can live with. Proper testing and mitigation, can eliminate radon as a health threat. For more information, visit the EPA web site on radon at http://www.epa.gov/radon.
