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 can can be left alone.

Radon is a colorless and odorless radioactive gas that has been estimated to cause 5,000 to 20,000 lung cancer deaths yearly. It is second only to smoking as a cause of lung cancer. It has been estimated that nearly 1 out of every 15 homes in the US has elevated radon levels.

Radon is produced when small amounts of uranium and radium in soil and rocks decay. Radon gas will also decay into smaller and radioactive particles that can be inhaled into the lungs where it can damage cells and cause lung cancer.

Radon is mainly released from soil, water and natural gas which have already been exposed to radon, from solar-heating systems that use radon-emitting rocks, and from uranium or phosphate mine tailings. Radon is naturally released in low concentrations, but inside your house, radon gas can become more concentrated. Lack of ventilation exhaust fans that bring in air from outside can increase the amount of radon in your home.

The Environmental Protection Agency suggests that homes be tested for radon, which should have a radon level of 4 picocuries per liter or less. For people selling their homes, the EPA recommends that the house be tested for radon, and radon levels be reduced, if necessary. Radon levels can be reduced by increasing the airflow into the house, keeping the vents open year round, and discouraging smoking in the house. For people buying homes, the EPA recommends obtaining radon test results in addition to information about radon reduction systems.

If you are planning to have your home tested for radon, the EPA recommends that the test be conducted in the lowest level of the home that is suitable for occupancy, and you should make sure that the test is done correctly by following the EPA Test Checklist.

There are two different types of testing devices available: passive devices and active devices. Passive devices, such as charcoal canisters, alpha track detectors, and charcoal liquid scintillation devices are exposed to air in the home for a specified amount of time, and sent to a laboratory to be analyzed. Active devices, like continuous radon monitors and continuous working level monitors, continuously measure and record the amount of radon in the air, and require operation by trained testers. These tests can be performed over a long term, or a short term, with the long term tests by active devices considered to be more accurate.

Underground heating oil tanks can pose many potential problems to both home buyers and sellers. They have been the source of many environmental problems such as contamination of surrounding soil and ground water.

Leaks are caused by the rust inside underground tanks, or by an electrical condition sparked by electric utility lines.

Buyers should have the tank inspected to make sure that it is structurally sound. Buyers who do not want an underground fuel tank can arrange for an above ground tank to be installed in the basement, an underground tank to be shut off. Cleanups of any leaks will also have to be taken care of.

For buyers, the underground heating oil tank should be written in the sales contract. For sellers, your lawyer should make sure that the description and condition of the underground heating oil is accurate and up-to-date.
