Solution
The best way to disinfect water is to boil it. This method is effective in killing most types of pathogens. However, if boiling is not possible, adding chlorine to the water can also be an effective method of disinfection. Straining water through a cloth can help remove large particles, but it does not kill bacteria or viruses. Adding sand to the water is not a recommended method of disinfection.
