In domestic applications, such as for drinking or bathing, the quality of the water source is as important as the quantity of available water. Water quality pertains to the chemical, physical, and biological characteristics of water, which determine its suitability for various uses. For drinking purposes, water must be free from harmful contaminants and pathogens, which could pose serious health risks. Similarly, for bathing, the water should not contain irritants or pollutants that could affect the skin or overall well-being. Additionally, aspects such as hardness, taste, and odor can significantly influence the perception of water quality. Therefore, both quantity and quality are crucial for ensuring safe and healthy domestic water usage.
