Quick Answer
Preppers should be aware of waterborne diseases such as cholera, dysentery, and giardiasis, which can be caused by contaminated water. These diseases can be life-threatening if left untreated. Effective water purification is crucial to prevent such illnesses.
Understanding Waterborne Diseases
Waterborne diseases are caused by pathogens, such as bacteria, viruses, and parasites, that are present in contaminated water. These diseases can be spread through direct contact with contaminated water, ingestion of contaminated food or water, or contaminated surfaces. Preppers should be aware of the following waterborne diseases:
- Cholera: A bacterial disease caused by Vibrio cholerae, which can cause severe diarrhea, vomiting, and dehydration. Cholera is often associated with contaminated water or food, particularly in areas with poor sanitation.
- Dysentery: A bacterial disease caused by Shigella, which can cause diarrhea, abdominal pain, and bloody stools. Dysentery is often spread through contaminated water or food.
Water Purification Techniques
Effective water purification is crucial to prevent waterborne diseases. Preppers should consider the following techniques to purify water:
- Boiling: Boiling water is the simplest and most effective method to kill pathogens. Bringing water to a rolling boil for 1-3 minutes can kill most bacteria, viruses, and parasites.
- Filtration: Using a water filter with a pore size of 0.2 microns can remove 99.99% of bacteria, viruses, and parasites from water.
- Disinfection: Using chlorine or iodine can disinfect water and kill pathogens. The recommended dosage is 2-4 parts per million (ppm) for chlorine and 1-2 ppm for iodine.
- Solar Disinfection (SODIS): Exposing water to sunlight for 6 hours can kill pathogens. This method is effective for clear, still water.
Prioritizing Water Purification
In a survival situation, water purification should be a top priority. Preppers should consider the following factors when choosing a water purification method:
- Effectiveness: Choose a method that can kill 99.99% of pathogens.
- Ease of use: Choose a method that is easy to use and requires minimal equipment.
- Portability: Choose a method that is portable and can be used in the field.
- Cost: Choose a method that is cost-effective and can be used in the long term.
