drinking water

Drinking water is the liquid necessary for human survival, primarily composed of H₂O. It hydrates the body, supports vital functions like temperature regulation, nutrient transportation, and waste elimination. Safe drinking water should be free from harmful contaminants such as bacteria, chemicals, and toxins. It is sourced from rivers, lakes, underground aquifers, and treated for purity before consumption. Proper hydration is essential for maintaining health, cognition, and physical performance. Access to clean drinking water is a fundamental public health goal, ensuring it’s safe, affordable, and available for all.
