Bacteria Removal

A common hazard of household water is contamination by potentially harmful bacteria and other micro-organisms. Short term gastrointestinal disorders and illnesses such as gastro-enteritis, giardiasis, typhoid, dysentery, cholera, and hepatitis have been linked to water contaminated by microorganisms. The micro-organisms which find their way into a water supply can come from a variety of sources including sewage, animal wastes, or dead and decaying animals. Public water systems are required by state and federal governments to provide biologically safe water. However, the safety of a privately-owned, individual water supply, such as a backyard well, rests in the hands of its owner.

How can an individual tell if household water is contaminated with bacteria? Bacteria in water cannot be seen, tasted, or smelled and many health-related symptoms are not immediate. Therefore, the only way to reliably determine if water is contaminated is by a laboratory test. Testing a water supply for a specific disease-causing organism can be expensive. Handling and culturing disease organisms requires special training and equipment. Instead, water supplies are usually tested for the presence of coliform bacteria. These bacteria are always present in the digestive systems of humans and animals, and can be found in their wastes. Coliform bacteria are also present in soil and in plant material. Most of these bacteria do not cause disease. They are simply an indicator that the water supply is contaminated and that disease-causing bacteria may be present.

The test for the presence of coliform bacteria is relatively inexpensive and easy to perform. The standard test is called total coliform. The Federal goal for total coliform in public drinking water is zero. Water samples that contain any coliform bacteria are generally reported as "total coliform positive." Federal regulations now require that public drinking water found to be "total coliform positive" must be analyzed with a fecal coliform or E.coli test. These fecal bacteria originate only in human and animal waste. It is unacceptable for fecal bacteria to be present in any concentration in a water supply.
