Drinking water treated with bleach is generally safe if done correctly, as bleach (sodium hypochlorite) can kill harmful bacteria and viruses. However, it’s crucial to use the right amount to avoid potential health risks. This guide will help you understand how to safely treat water with bleach and answer common related questions.
How to Safely Treat Water with Bleach?
When using bleach to disinfect water, it’s vital to use unscented household bleach with a concentration of 5.25% to 8.25% sodium hypochlorite. Here’s a step-by-step guide:
- Determine the Water Volume: Measure the amount of water you need to treat.
- Add the Correct Amount of Bleach: Use the following guidelines:
- For clear water: Add 2 drops of bleach per quart (1 liter) of water.
- For cloudy water: Add 4 drops per quart (1 liter) of water.
- Mix Thoroughly: Stir the water thoroughly to ensure even distribution of bleach.
- Let It Stand: Allow the water to sit for at least 30 minutes. The water should have a slight chlorine smell. If not, repeat the dosage and let it stand for another 15 minutes.
Why Use Bleach to Treat Water?
Bleach is an effective disinfectant that can eliminate pathogens like bacteria, viruses, and some parasites. This makes it a reliable option for ensuring safe drinking water in emergency situations or when traveling in areas without access to clean water.
What Are the Risks of Drinking Bleach-Treated Water?
While bleach is effective for water treatment, improper use can pose health risks:
- Overuse: Adding too much bleach can lead to chlorine poisoning, causing symptoms like nausea, vomiting, and throat irritation.
- Underuse: Insufficient bleach may not kill all harmful microorganisms, leaving the water unsafe to drink.
- Chemical Reactions: Mixing bleach with other chemicals can produce toxic gases.
Practical Example: Treating Water in Emergencies
Imagine you’re camping in a remote area, and your only water source is a river. The water appears cloudy, making it unsafe to drink directly. By following the guidelines above, you can treat the water with bleach, ensuring it’s safe for consumption. This method is especially useful when boiling water is not an option.

People Also Ask
Is it safe to drink water treated with bleach regularly?
Drinking water treated with bleach is safe in emergencies or when no other options are available. However, for regular use, it’s best to rely on treated municipal water or other purification methods like filters or boiling.
How does bleach kill bacteria in water?
Bleach contains sodium hypochlorite, which releases chlorine. Chlorine oxidizes the cell walls of bacteria and viruses, effectively killing them and making the water safe to drink.
Can you use scented bleach for water treatment?
No, only unscented household bleach should be used for water treatment. Scented bleach contains additional chemicals that are not safe for consumption.
What are the signs of chlorine poisoning?
Symptoms of chlorine poisoning include difficulty breathing, chest pain, vomiting, and eye irritation. If you suspect chlorine poisoning, seek medical attention immediately.
How long can bleach-treated water be stored?
Bleach-treated water can be stored for up to six months if kept in a clean, airtight container away from sunlight. It’s important to label the container with the date of treatment.
Conclusion
Using bleach to treat water is a practical solution in emergencies or when access to clean water is limited. By following the correct procedures and understanding the potential risks, you can ensure the water you consume is safe. For regular use, consider investing in a reliable water filtration system or other purification methods. If you have further questions about water treatment or safety, consult a water quality expert or health professional.
