Camping, Hiking, Travel

While the water flowing in the streams and rivers of the backcountry may look pure, it can still be contaminated with bacteria, viruses, parasites, and other contaminants.

When planning on camping or hiking, it is important to remember your water needs. There are many approaches you can take to providing yourself and others in your group with safe water for both drinking and sanitation.

Before your next camping or hiking trip, check out the links below.

In addition to using safe drinking and recreational water, it is important to also protect yourself and others from waterborne illness by paying attention to good sanitation practices:

  • Disposing of human waste appropriately. When possible, use permanent sanitation facilities (toilets and latrines). If these facilities are not available, dispose of human waste by burying it at least 8 inches deep and at least 200 feet from natural waters.
  • Practicing good personal hygiene. If possible, wash hands with soap and clean, running water before handling food or eating, and after using the toilet.
