Should I boil rainwater before drinking it?

Importance of Boiling Rainwater

Boiling rainwater is a crucial step in making it safe for drinking. Even though rainwater is considered a natural source, it can still contain bacteria, viruses, and other contaminants that can cause waterborne illnesses. In fact, a study found that untreated rainwater can harbor up to 100 colony-forming units (CFU) of bacteria per milliliter.

Techniques for Boiling Rainwater

To boil rainwater effectively, you’ll need a clean container with a lid to prevent contamination. Bring the rainwater to a rolling boil for at least 1-3 minutes to kill bacteria and viruses. The boiling time may vary depending on the source of the rainwater and the altitude. As a general rule, boil rainwater for 1 minute at elevations up to 6,500 feet, 2 minutes at elevations between 6,500 and 8,000 feet, and 3 minutes at elevations above 8,000 feet.

Tips for Boiling Rainwater in the Field

When boiling rainwater in the field, it’s essential to use a portable stove or camping stove. Make sure to use a pot that’s at least 3 quarts in size to allow for proper boiling. If you’re in a survival situation, you can also use a makeshift pot or a container made from a plastic bottle. To speed up the boiling process, you can use a few rocks to create a makeshift solar still or a fire pit to heat the water. Always prioritize boiling rainwater to ensure a safe and healthy drinking water supply.
