Quick Answer
Distilled water is generally safe for cooking and drinking in emergency situations or when other sources of clean water are not available, but it may lack beneficial minerals.
Purification Methods
Distilled water is produced through a process that involves boiling water and then collecting the condensed steam, which is free from many contaminants. This method is often considered a benchmark for water purification. In a survival situation, a solar still or a DIY distillation apparatus can be used to obtain clean drinking water. For example, a simple still can be created using a plastic bottle, some twine, and a container to collect the distilled water.
Distilled Water Characteristics
Distilled water lacks the beneficial minerals that are naturally found in water, such as calcium and magnesium. While this may not be a concern in the short term, long-term consumption of distilled water can lead to mineral deficiencies. In a survival situation, it’s essential to find ways to replenish these minerals, such as by eating food rich in minerals or by using water purification tablets that contain minerals.
Practical Considerations
In a survival situation, it’s crucial to prioritize water purification to avoid waterborne illnesses. Distilled water can be a reliable source of clean drinking water, but it may not be the most practical solution in all situations. For example, distillation requires energy and can be time-consuming, which may not be feasible in a prolonged survival situation. In such cases, other methods of water purification, such as filtration or disinfection, may be more practical and effective.
