As a water treatment expert, I understand the importance of safe drinking water, especially in emergency situations or areas where clean water is scarce. The process of disinfecting water with bleach is a common method to kill harmful pathogens and make the water safe for consumption. However, it’s crucial to follow the correct procedure and proportions to ensure the water is not only safe but also palatable.
When it comes to the use of bleach for water disinfection, the general guideline is to add 1/4 teaspoon of unscented household bleach per gallon of cloudy water. This equates to approximately 16 drops or about 1.50 milliliters. For clear water, the amount can be reduced to 8 drops per gallon. If you are using metric measurements, this translates to 4 drops of bleach per liter of cloudy water.
It is important to note that the water should be cloudy to begin with, as the cloudiness can help the bleach to disperse evenly throughout the water. If the water is clear, it may not be necessary to add as much bleach, and the process may need to be adjusted accordingly.
After adding the bleach, the water should be allowed to stand for a minimum of 30 minutes to ensure that the disinfection process is effective. This time frame allows the chlorine in the bleach to kill most of the harmful bacteria and viruses present in the water.
Once the standing time has elapsed, the water should be tasted to check for a slight chlorine odor. This is a good indication that the water has been adequately disinfected. If the water does not have a chlorine taste, it may need to be re-treated or left to stand for a longer period.
Storing the disinfected water is also a critical step. It should be kept in clean, disinfected containers with tight covers to prevent recontamination. If the water develops an unpleasant taste over time, it can be improved by boiling it for 1 minute or adding a pinch of salt to a quart of water.
It is also worth mentioning that while bleach is effective for disinfection, it is not a long-term solution for water treatment. In the long run, it is better to seek out a more sustainable and reliable source of clean water.

Add 1/4 teaspoon (or 16 drops; about 1.50 milliliters) of bleach for each gallon of cloudy water (or 4 drops of bleach for each liter or each quart of cloudy water). Let it stand for 30 minutes or longer before you use it. Store the disinfected water in clean, disinfected containers with tight covers.
