In any survival situation, having access to clean drinking water is crucial. Contaminated water can lead to severe illness or even death, making water purification a top priority. One of the most effective methods for disinfecting water is using household bleach. This common, inexpensive item can be a lifesaver when used correctly.
Understanding Bleach Shelf Life
Bleach’s limited shelf life
While bleach is a powerful disinfectant, it has a limited shelf life. Over time, bleach loses its potency and becomes less effective at killing harmful microorganisms. Typically, an unopened bottle of bleach remains potent for about six months to a year. After this period, its effectiveness diminishes, so it’s essential to rotate your stock regularly.
Storage tips
To maximize the shelf life of bleach, store it in a cool, dark place. Avoid exposing it to heat or sunlight, which can accelerate its degradation. Always keep the bottle tightly sealed to prevent it from losing its strength.
The Calcium Hypochlorite Alternative
Advantages over liquid bleach
For those looking for a longer-lasting alternative to liquid bleach, calcium hypochlorite is an excellent option. Commonly found in pool shock products, calcium hypochlorite is stable and has a much longer shelf life than liquid bleach. It’s also more concentrated, meaning a small amount can purify a large volume of water.
Forms and availability
Calcium hypochlorite is available in granular form and can be found in most pool supply stores. When using it for water purification, ensure you are using a product that is free from additives like algaecides and anti-fungal agents, which can be harmful.
How to Bleach Water: Step-by-Step Guide
- Gather your supplies
You’ll need unscented household bleach (with 5.25-8.25% sodium hypochlorite), a clean dropper, and a container for your water. - Calculate the dosage
The general rule is to add 8 drops of bleach per gallon of clear water. If the water is cloudy, use 16 drops per gallon. Stir the mixture thoroughly and let it sit for at least 30 minutes. - Check the smell
After 30 minutes, the water should have a slight chlorine odor. If it doesn’t, add another 8 drops of bleach per gallon and let it sit for an additional 15 minutes. If the water still doesn’t smell of chlorine, it may be too contaminated to safely drink. - Storing purified water
Once treated, store your purified water in clean, covered containers. If possible, use containers with tight-fitting lids to prevent recontamination.
Safety Precautions
Avoid overuse
Using too much bleach can be harmful. Always stick to the recommended dosage and never drink bleach directly.
Label your containers
Clearly label containers of treated water to avoid confusion. This helps ensure that everyone in your household knows the water is safe to drink.
Conclusion: Be Prepared
Knowing how to properly bleach water is a critical survival skill. It’s a simple yet effective way to ensure you have access to clean drinking water in an emergency. By understanding the shelf life of bleach, considering alternatives like calcium hypochlorite, and following the correct procedures, you can be prepared to handle any situation where safe water is essential.
Remember, preparation is key to survival. Keep your supplies stocked, stay informed, and always have a plan for purifying water. Your life could depend on it.
