Water quality refers to how clean or dirty water is and whether it is safe for people and the environment. It is determined by looking at different factors like the presence of pollutants, chemicals, and organisms in the water. Good water quality means the water is clear, has low levels of harmful substances, and is safe for drinking, swimming, and supporting animal and plant life. Factors such as industrial waste, agricultural run-off, and sewage can affect water quality, making it an important issue to study and manage. Understanding water quality helps us protect our health and the ecosystems that depend on clean water.
