As an expert in the field of water purification, I can provide you with a comprehensive answer on how long you should boil water to purify it.
Water is a vital resource for human survival, and ensuring its safety is of paramount importance. Boiling is one of the oldest and most effective methods of purifying water, as it can kill most types of bacteria, viruses, and parasites that may be present in the water. However, the duration for which the water should be boiled depends on various factors, including the altitude at which you are located and the quality of the water source.
The US Center for Disease Control (CDC) recommends that water should be brought to a rolling boil for at least 1 minute to effectively kill pathogens. This is a general guideline and assumes that the water is at sea level. At higher altitudes, where the boiling point of water is lower due to reduced atmospheric pressure, the CDC suggests that water should be boiled for a longer duration.
Specifically, at altitudes greater than 6,562 feet (or 2000 meters), the CDC advises boiling water for 3 minutes. This extended boiling time is necessary because the lower boiling point at higher altitudes means that pathogens may not be killed as quickly as they would be at lower altitudes.
It is important to note that boiling water is effective against most, but not all, pathogens. Some bacteria and viruses may be more resistant to heat and may require longer boiling times or additional treatment methods. Additionally, boiling does not remove chemical contaminants from water, so if the water source is suspected to contain chemicals, further purification methods such as filtration or chemical treatment may be necessary.
When boiling water for purification, it is also crucial to consider the source of the water. If the water comes from a known contaminated source, it may require additional treatment steps beyond boiling. For example, if the water is known to contain giardia or cryptosporidium, which are parasites that can cause gastrointestinal illness, it is recommended to boil the water for at least 10 minutes to ensure that these parasites are killed.
Furthermore, the quality of the water can also affect the boiling time. If the water is murky or has a high level of suspended particles, it may be beneficial to filter the water before boiling to remove these impurities. This can help to improve the taste and clarity of the water and may also reduce the risk of recontamination after boiling.
In conclusion, boiling water is a simple and effective method for purifying water, but the duration of boiling should be adjusted based on the altitude and the quality of the water source. It is always best to follow the recommendations of health authorities and to consider additional purification methods if the water source is known to be contaminated or if there are concerns about chemical contamination.

US Center for Disease Control: --Boiling can be used as a pathogen reduction method that should kill all pathogens. Water should be brought to a rolling boil for 1 minute. At altitudes greater than 6,562 feet (greater than 2000 meters), you should boil water for 3 minutes.--Dec 9, 2015
