Quick Answer
Storing water in plastic milk jugs is generally not recommended for long-term use due to the risks of leaching and bacterial contamination, making it better to opt for BPA-free water storage containers specifically designed for this purpose.
Choosing the Right Container
When selecting a container for long-term water storage, look for ones made from BPA-free, food-grade plastic. Polyethylene or polypropylene are suitable options. Avoid containers that have been previously used for storing chemicals or other contaminants. Milk jugs, in particular, may contain small amounts of residual milk proteins and fats that can compromise water quality. Opt for containers with a capacity of at least 1 gallon to minimize the risk of contamination from external sources.
Cleaning and Preparing Containers
Before storing water, thoroughly clean and sanitize the containers using a solution of 1 tablespoon of unscented bleach per gallon of water. Let the solution sit for 10-15 minutes to ensure thorough disinfection. Rinse the containers thoroughly with clean water, and then dry them completely with a clean towel.
Long-Term Storage Considerations
When storing water in containers, it’s essential to monitor the quality regularly to prevent bacterial contamination and off-flavors. Check the water for signs of spoilage every 6-12 months. If you notice any unusual odors, colors, or sediment, discard the water immediately and replace it with fresh supplies. Consider storing the containers in a cool, dark area with minimal exposure to sunlight and extreme temperatures.
