Quick Answer
After flooding, decontaminate water sources by boiling, disinfecting, or filtering to remove bacteria, viruses, and other contaminants. Use a combination of methods to ensure safe drinking water. This process can be achieved with the right equipment and knowledge.
Selection of Decontamination Methods
When choosing a decontamination method, consider the severity of contamination and the equipment available. Boiling water is the simplest and most effective method, killing all bacteria, viruses, and protozoa. Bring water to a rolling boil for 1-3 minutes, depending on the altitude and water quality. Disinfection using chlorine or iodine tablets can also be effective, but may not remove heavy metals or other inorganic compounds. Filtering water through a ceramic or carbon filter can remove many contaminants, but may not kill all bacteria and viruses.
Decontamination Process
To decontaminate water using the boil method, fill a pot with water and bring it to a boil. Reduce the heat to a simmer and let it boil for the recommended time. Remove the pot from the heat and let it cool before storing the water in a clean container. For disinfection, add the recommended amount of chlorine or iodine tablets to the water, stir well, and let it sit for the recommended time. For filtering, use a ceramic or carbon filter that meets the NSF/ANSI Standard 53 for removal of contaminants.
