The United States Environmental Protection agency goes to great lengths to ensure that the water supplies of the nation are safe. Unfortunately, approximately fifteen per cent of the population is not part of the public supply system and they normally have to rely on privately owned boreholes. These boreholes are not regulated in any way and it is up to the owner to make sure that they do well water testing in order to make sure that it is safe for drinking and other domestic uses.

Owners of boreholes must make sure that they have the quality of the water tested regularly. Even if it looks clean, it may contain a variety of bacteria that can be harmful to the health of those drinking it. The University of Montana conducted studies of privately owned boreholes and found that close on forty per cent of the samples contained dangerous levels of coliform bacteria and many samples even contained unacceptably high levels of nitrate.

It is not really feasible to test regularly for all the various contaminants that can be found in privately owned boreholes. The tests are expensive. Experts advise that it is necessary to test for coliform bacteria and nitrates, however. Both of these are common contaminants and they can pose a threat to human health. Tests should also be conducted for the presence of dissolved solids, but this contaminant is mostly cosmetic.

The danger of contaminated boreholes should not be underestimated. Young people and those with debilitating diseases such as cancer and AIDS patients are especially vulnerable. Hepatitis, neurological disorders and dysentery are common. Diarrhea is another commonplace consequence. Borehole products can even lead to reproductive problems and many cases of neurological disorders have been linked to the use of suspect borehole products.

Boreholes are vulnerable to contamination of a wide variety of agents that can be harmful to humans. This is especially the case in areas where there is heavy industrial operation or mines. If lead pipes are used there should also be cause for concern. Even farming operations that use pesticides and other chemicals can contaminate the underground table, thereby causing harm to the users of boreholes.

Experts agree that borehole contents should be tested at least once a year. However, more frequent or incidental tests should be undertaken when certain signs occur. If any user becomes ill or if there have been incidents of flooding it may be a good idea to have the borehole tested. If there is any change in the color or taste alarm bells should also ring.

There are a number of places that can test boreholes. Owners should be careful, however. Some test facilities are not recognized and their results are suspect. It may be better to use those facilities connected to local authorities or to local academic institutions. The internet is a wonderful source of information in this regard. Advice and guidance can also be sought from other borehole owners.

Having a private borehole is, for some people ate least, a privilege and for others it is the only way in which they can enjoy baths and moisture. Great care should be taken, however, to ensure that it is safe and that it does not contain potentially harmful contaminants. Tests should be conducted regularly and the quality of the product should be safe guarded.
