Quick Answer
Dew can be a reliable source of water in the morning, but it's essential to check its quantity and quality before consumption. Collect dew from surfaces that are exposed to the sky and have minimal vegetation. Use a cloth or plastic bag to absorb the dew.
Choosing the Right Surfaces
When searching for dew, select surfaces that are exposed to the sky and have minimal vegetation, such as tree trunks, rocks, or the center of leaves. Avoid surfaces with high humidity, like moss or lichen, as they may contain pollutants. The ideal surface should be at least 2 feet tall to allow for easy collection.
Collection Techniques
To collect dew, use a clean cloth or plastic bag with a mesh material to allow water to pass through while keeping out debris. Place the cloth or bag over the chosen surface overnight and secure it with twine or a rock. In the morning, gently remove the cloth or bag and wring it out. The collected dew should be clear and taste free of pollutants.
Prioritizing Dew Collection
In a desert environment, dew collection should be prioritized in the following order: 1) dew from surfaces that are at least 3 feet tall to minimize contamination, 2) dew from surfaces with a smooth, non-porous texture, and 3) dew from surfaces that are in the shade during the day to reduce evaporation. This prioritization ensures the collection of the cleanest and most abundant dew possible.
