Well Water Testing Protects Family Health

By Marissa Velazquez


In many rural areas, homes depend on wells to supply for their needs. While the Environmental Protection Agency requires that public supplies be tested to ensure they meet certain standards, such tests are not generally required for private wells in the United States. Well water testing ensures a home's supply is safe for the family to consume.

Several tests that are performed are for indicator organisms and chemicals that show the likelihood of more dangerous contaminates. While these indicator strains or chemicals may not cause illness, they often occur with more dangerous ones for which testing is more difficult. Their presence indicates potential contamination by such problems as raw sewage.

Bacteria from the digestive systems of other warm blooded animals and humans is of grave concern. Labs often perform a total coliform test to indicate the presences of these bacteria in the submitted sample. If these counts return large numbers, there is a greater chance of disease causing organisms in the supply that can bring harm to those who consume the product.

From the microbiological standpoint, the more specific E. Coli test is often used. Positive E. Coli tests indicate contamination by fecal material. While the indicator E. Coli that grow on the microbiologist plates are generally harmless, there is a greater chance of germs that do cause diseases such as hepatitis, diarrhea or dysentery are present. This indicator strand of E. Coli should not be confused with a more harmful strain often on the news.

The pH of the sample indicates if it is acid or basic. The pH affects the taste as well as the looks of one's supply. The pH of a neutral sample is 7.0. If numbers are much higher or lower than 7.0, the liquid can leach heavy metals from pipes to the tap. Liquids that are not neutral can also damage pipes and over time make the occupants of the home sick.

Nitrates are a part of many foods, but should be in the pipes of the home as continual consumption can make you ill. Sources of these chemicals include flooded sewers, septic tanks, animal waste and polluted storm waters. They can also come from farm runoff, affecting the quality of wells in the area. In addition, natural deposits in the area often increase their levels.

In some regions, volatile organic compounds from fuel or industrial pollution contaminate wells. The exact VOCs for which one should test depend on the location in which one lives. If they are a problem in your region, the local health department can tell you the tests to have completed.

Some health concerns are regionally specific. For example, heavy metals may be a problem, especially in the Western USA. In other regions, there may be specific bacteria which is of concern and for which the sample should be tested. The local health department of the laboratory can help homeowners determine the tests which are necessary to ensure their safety.

In general, it is a good idea to test samples of the supply at least once per year. Additional tests should be submitted if one notes a difference in quality or if there have been local land disturbances. With proper well water testing you protect the health of all living in the home.
