Boiling is the most straightforward method to disinfect water without using chlorine. Bring water to a full rolling boil for at least one minute (or three minutes at elevations above 6,500 feet) to kill most pathogens. UV purification, using portable UV light devices or sunlight exposure in clear bottles (SODIS method), can also effectively disinfect water. Distillation, involving boiling water and then condensing the steam back into water, removes contaminants, including bacteria and viruses.
FAQs & Answers
- How long should you boil water to disinfect it? Boil water for at least one minute to kill most pathogens; at elevations above 6,500 feet, boil for three minutes for effective disinfection.
- Can sunlight be used to disinfect water? Yes, the SODIS method uses sunlight exposure in clear bottles to disinfect water through UV radiation effectively.
- Does distillation remove all contaminants from water? Distillation removes most contaminants, including bacteria and viruses, by boiling water and collecting the condensed steam.
