All natural water contains minerals and gases, and even microorganisms.
Most are harmless, but a few can make you sick. Coliform bacteria, nitrates, sodium, lead and arsenic are just a few examples of health dangers lurking in your drinking water. The information in this brochure will help you keep your family's drinking water safe. Leaking septic tanks are a major source of bacteria contamination in well water, but other sources include runoff from woodlands and pastures, from wastes deposited directly into lakes and streams, and from improperly sealed, abandoned wells. Coliforms originate in the intestines of warm blooded animals.
