Tap water is the water supplied through plumbing systems to homes and businesses. It is typically sourced from rivers, lakes, or underground aquifers and is treated to remove contaminants, making it safe for drinking and other uses. In many countries, tap water is regulated by government agencies to ensure its quality and safety. In addition to drinking, tap water is used for cooking, cleaning, and sanitation. Many people prefer tap water over bottled water due to its lower cost and environmental benefits. However, the quality of tap water can vary based on location and local infrastructure, so it's important to be aware of any potential issues.
