Should You Cook Water Collected From Transpiration Bags?

Why Treatment is Necessary

Water collected from transpiration bags may contain contaminants, such as bacteria, viruses, and protozoa, which can be present in the plant material or in the atmosphere. These pathogens can cause waterborne illnesses, including cholera, dysentery, and giardiasis. To ensure safe drinking water, it’s essential to treat water collected from transpiration bags using a combination of methods.

Treatment Options

There are several treatment options available for water collected from transpiration bags, including boiling, solar disinfection (SODIS), and use of water filters or purification tablets. Boiling is the most effective method, as it kills all pathogens and contaminants. To boil water effectively, bring it to a rolling boil for at least 1 minute at an elevation of up to 6,562 feet (2,000 meters). If boiling is not possible, SODIS can be an effective alternative. Simply place the water in a clear plastic bottle and leave it in direct sunlight for at least 6 hours, or until the water reaches a temperature of at least 140°F (60°C).

Additional Considerations

When collecting water from transpiration bags, it’s essential to follow proper collection and storage procedures to minimize the risk of contamination. Use a clean container to collect the water, and store it in a sealed container to prevent contamination from the environment. If the water is cloudy or has an unusual color or odor, it’s best to err on the side of caution and discard it.
