Q.Our Lake has been contaminated by coliform bacteria. How can I make sure that the water is safe to drink?

A. Water is the breeding ground for an almost unbelievably large variety of organisms. Water does not produce these organisms. It merely is an ideal medium in which they can grow. These organisms gain entry into water through a variety of sources. They enter the water supply from all sorts of natural causes, surface drainage and sewage.

The most effective and economical method of treating water for a household is to use ultraviolet light. The use of ultraviolet light is an attempt to imitate nature.
