Why is it important to keep water in cool, dark places?

Keeping water in cool, dark places is crucial primarily for the prevention of bacterial growth. Bacteria thrive in warm temperatures and in environments that are exposed to light. When water is stored in cool conditions, the growth of these microorganisms is inhibited, ensuring that the water remains safe and healthful for consumption.

Additionally, dark storage prevents the breakdown of substances in the water that could occur due to light exposure, which can also be important for maintaining quality. Effective storage practices help in preserving the integrity of water, both in terms of its safety and its quality, making it essential for public health and environmental management.
