Quick Answer
Reverse osmosis water is generally suitable for long-term storage, but it requires careful handling and storage to prevent bacterial growth and contamination.
Storage Considerations
Reverse osmosis water is a good choice for long-term storage due to its low total dissolved solids (TDS). However, it is essential to store it in a clean container with a secure lid, such as a food-grade plastic or glass bottle. Avoid using containers with a history of contamination or exposure to chemicals.
Additional Precautions
When storing reverse osmosis water, it’s crucial to consider the risk of bacterial growth. Typically, reverse osmosis water has a pH level close to 7, which is slightly alkaline, and a TDS of around 10-50 parts per million. To prevent bacterial growth, store the water at a temperature below 40°F (4°C) or add a small amount of chlorine (about 2-3 parts per million) as a disinfectant. Regularly inspect the container for signs of leakage, contamination, or degradation.
Storage Shelf Life
In ideal storage conditions, reverse osmosis water can last indefinitely. However, if stored in less-than-ideal conditions or with inadequate handling, it may not meet the recommended water quality standards. To maximize shelf life, store the water in a dark, cool place, away from direct sunlight and potential sources of contamination. Regularly check the water’s clarity, odor, and taste for signs of degradation.
