Quick Answer
Plastic containers are better suited for long-term water storage due to their durability, resistance to environmental conditions, and ability to withstand chemical reactions with water. Glass containers, on the other hand, are more prone to cracking and shattering, which can lead to water contamination.
Choosing the Right Container
When it comes to storing potable water for the long term, the container you choose is crucial. Plastics, specifically low-density polyethylene (LDPE) or high-density polyethylene (HDPE), are ideal due to their durability and resistance to environmental conditions such as UV light, extreme temperatures, and chemical corrosion. These plastics are also less reactive, reducing the risk of chemical contamination of the water.
Considerations for Plastic Containers
When selecting plastic containers, look for ones that are specifically designed for food-grade storage. These containers should have a thickness of at least 0.010 inches (0.25 mm) and be manufactured in a facility that meets Food and Drug Administration (FDA) standards. It’s also essential to ensure that the containers are free of any contaminants, such as Bisphenol A (BPA), which can leach into the water.
Preparing and Maintaining Containers
Before storing water in plastic containers, make sure to clean and dry the containers thoroughly. Use a mild detergent and rinse with water, then allow the containers to air dry. To prevent contamination, store the containers in a well-ventilated area, away from direct sunlight and chemicals. Regularly inspect the containers for signs of wear, such as cracks or dents, and replace them if necessary to ensure the water remains safe for consumption.
