Quick Answer
Use BPA-free and food-grade containers, and rinse them thoroughly before storing water to minimize chemical leaching.
Choosing the Right Container
Select containers made from BPA-free, food-grade materials such as stainless steel, glass, or HDPE. Avoid plastic containers, especially those marked with a #7 recycling code, as they may contain BPA or other chemicals that can leach into water. When purchasing containers, look for certifications like NSF 61 or FDA compliance to ensure they meet safety standards.
Storage and Maintenance
Rinse your containers thoroughly before storing water to remove any residual chemicals or manufacturing residues. Use a mixture of water and white vinegar (1:1 ratio) to scrub the containers, then rinse them again with clean water. Store the containers in a clean, dry environment, away from direct sunlight and chemicals, to prevent contamination.
Monitoring and Testing
Regularly inspect your containers for signs of wear, such as scratches or cracks, which can compromise their integrity. Consider testing your stored water for pH levels, turbidity, and chemical contaminants to ensure its safety for consumption. Use a water testing kit or send a sample to a certified laboratory for analysis.
