What are the properties of polluted water?

Polluted water typically exhibits several key properties, including altered color, turbidity, and unpleasant odor, which result from contaminants such as chemicals, heavy metals, and organic matter. It may also have elevated levels of pathogens, leading to health risks for humans and aquatic life. Additionally, polluted water often has reduced dissolved oxygen levels, which can harm aquatic ecosystems and disrupt the natural balance of the environment. Overall, these properties indicate the presence of harmful substances that compromise water quality.
