Quick Answer
If your water doesn't reach a rolling boil, continue boiling for at least 3-5 minutes to kill harmful bacteria and viruses. Alternatively, you can use a solar still or water purification tablets as an alternative method of water purification. This ensures the water is safe to drink.
Boiling Time
If the water doesn’t reach a rolling boil, it’s essential to boil it for an extended period. For water temperatures of 212°F (100°C), boiling for 3-5 minutes is recommended to kill bacteria and viruses, including Giardia and Cryptosporidium. You can also use a thermometer to check the water temperature and ensure it reaches 165°F (74°C) for at least 30 seconds.
Solar Still Method
A solar still is a simple, low-tech method for purifying water using the power of the sun. To create a solar still, dig a shallow hole in the ground and place a container in the center. Add the contaminated water to the container and cover it with a clear plastic sheet. Weigh down the edges with rocks and create a small indentation in the center of the plastic sheet. As the sun heats the water, water vapor will rise and collect in the indentation, where you can collect it as clean drinking water.
Water Purification Tablets
Water purification tablets are a convenient and portable method for purifying water. These tablets contain disinfectants such as chlorine or iodine that kill bacteria, viruses, and other microorganisms. To use water purification tablets, follow the manufacturer’s instructions and add the recommended amount of tablets to the water. Allow the tablets to dissolve and sit for the recommended time, usually 30 minutes to an hour, before drinking the water.
