Water is a basic necessity of life. Springs, seeps, streams, rivers, ponds, or lakes may all be used as a source for drinking water in the back country however, some sources may not be safe to drink. Clean, safe water may be obtained from these sources by boiling. If boiling is not practical, the water may be treated by a device tested to The Standard or to USACHPPM P248. When a tested device is used, maintained, and stored according to the directions, it can provide water safe from microbial contamination.
