Quick Answer
Using bleach to disinfect stored water is not recommended due to the potential for sodium hydroxide formation, which can cause severe stomach pain, vomiting, and even death if consumed in high amounts.
Risks of Chlorine Bleach
When you mix chlorine bleach with water, a reaction occurs that can release sodium hydroxide, also known as lye. Sodium hydroxide is a caustic substance that can be extremely hazardous to your health. When ingested, it can cause severe stomach pain, vomiting, and even death. Ingesting 1-2 teaspoons of sodium hydroxide can be fatal.
Bleach Concentration and Mixing Techniques
If you still want to use bleach for water disinfection, it’s essential to follow proper procedures. The recommended concentration is 1 tablespoon of unscented chlorine bleach per 1 gallon of water. Mix the bleach with the water in a clean container, but never add the water to the bleach. This can cause the sodium hydroxide to form and increase the risk of contamination. Allow the mixture to sit for at least 30 minutes before consumption to ensure the chlorine has fully disinfected the water.
Alternative Disinfection Methods
A safer and more effective option for disinfecting stored water is to use water purification tablets or filter systems specifically designed for this purpose. These systems can remove bacteria, viruses, and other contaminants from the water without the risk of sodium hydroxide formation. Other alternatives include using iodine tablets or UV light disinfection systems. Always follow the manufacturer’s instructions and take necessary safety precautions when handling any disinfection method.
