"Warning to Water Bottlers: Heat May Be Hiding a Toxic Secret. A concerning discovery has been made about the safety of bottled water, particularly when stored in hot environments. Research suggests that elevated temperatures can cause the plastic containers to leach chemicals into the water, potentially contaminating it with harmful substances. As the summer months approach, many people will be stocking up on bottled water, but with this new information, it's essential to store them in a cool, shaded area to minimize the risk of contamination."
Keep your bottled water stored in a cool place. Higher temperatures can trigger the release of harmful chemicals in the plastic to seep into the water.
