Coliform Bacteria are commonly found in our natural environment and are the most likely source of acute water-borne disease. Globally millions of cases of bacterial illness occur every year, many of them fatal. Even mild cases can result in diarrhea, vomiting, cramps, and other gastrointestinal symptoms. Since contaminated water may not taste or smell "bad", most cases of water-borne disease are impossible to identify without the correct testing tools and methods. The presence of bacteria in drinking water indicates that treatment of the water is required or if the water is being treated that the treatment methods are not adequate to remove all viable microbes. When treatment fails, drinking water may become potentially toxic.
