Why Is Fast Flowing Water Considered Safe to Drink?

Water from a fast flowing source is considered safer than stagnant water.

When choosing drinking water from an outdoor source, it is better to select fast flowing water than stagnant water, which is more likely to contain impurities. It is a wise choice, however, to purify all water collected from outdoor sources.

Appearance

Water may appear to be sparkling clean but contain impurities. When water is not in motion, it collects dirt and debris. Fast flowing water has a decreased chance of containing impurities due to its continuous motion.

Quality

The water source may be close to a factory, which can cause contamination. Water quality may be affected by animal carcasses or feces in the source.

Disease

Drinking contaminated water can result in gastroenteritis and diarrhea. Unclean water may contain bacteria, viruses and parasites.

Purification

It is best to boil or filter all drinking water from an outdoor source. Other methods of purification include chlorine and iodine tablets or filters. Supplies for purifying water can be found at stores that sell camping equipment.

Consideration

When camping or doing activities outdoors, it is best to bring enough water to last you for your trip. You should drink water from an outdoor source only if it is necessary for survival.
