Quick Answer
Contaminated water is a leading cause of illness and death in survival situations due to the presence of pathogens, chemicals, and other contaminants that can cause dehydration, diarrhea, and other waterborne diseases.
Waterborne Diseases and Pathogens
Contaminated water can harbor a wide range of pathogens, including bacteria, viruses, and protozoa, that can cause severe illness and even death. According to the World Health Organization, waterborne diseases are responsible for an estimated 80% of all illnesses and 6% of all deaths worldwide. Some common waterborne pathogens include Giardia, Cryptosporidium, and E. coli.
Effects of Water Contamination
The effects of water contamination can be severe and long-lasting, and can include dehydration, diarrhea, vomiting, and stomach cramps. In severe cases, contaminated water can also cause life-threatening illnesses such as cholera, typhoid fever, and dysentery. For example, a person can die from dehydration within 3-5 days if they are not treated with proper hydration and medical care.
DIY Water Distillation Techniques
In survival situations, it is essential to have a reliable method of purifying water to prevent waterborne diseases. One effective DIY method of water distillation is to use a solar still, which can be created using a container, a rock, and a clear plastic sheet. To build a solar still, dig a shallow hole in the ground and place a container in the center. Pour contaminated water into the container and cover it with a clear plastic sheet. Place a rock on the center of the plastic sheet and weigh it down with a heavy object. As the sun heats the plastic sheet, water vapor will rise and condense on the underside of the plastic sheet, allowing you to collect clean water. This method can produce up to 1 liter of clean water per hour.
