Quick Answer
Water from dew: myths vs facts is often misunderstood. Collecting dew can be a viable source of water in a survival situation. However, it requires proper techniques and understanding of the environment.
Assessing Dew Collection
To effectively collect dew, you need to understand the conditions required. Dew typically forms when the air temperature cools overnight, causing the water vapor to condense. This usually occurs when the temperature drops below 40°F (4°C) and the humidity is high. In ideal conditions, dew can provide 1-2 ounces of water per square foot.
Collecting Dew
There are several methods to collect dew, including using a cloth or plastic sheet. Place a clear plastic bag or a cloths over a branch or a string, allowing dew to collect in the bag or on the cloth. Weigh down the edges with rocks to prevent air from entering. The ideal time to collect dew is in the early morning, when the dew is at its highest concentration.
Practical Considerations
Keep in mind that collecting dew requires patience and planning. It’s not a reliable source of water, especially in dry or windy conditions. In addition, dew can be contaminated with pollutants, bacteria, or insects, making it necessary to filter or boil the water before consumption. When collecting dew, avoid areas with pesticide or herbicide use, as these can contaminate the water.
