Pollution from industrial and domestic sources can have a devastating impact on the water quality of rivers. This can lead to a number of problems, including:

• Aquatic life: Pollution can kill fish and other aquatic animals, or make them sick. This can disrupt the food chain and have a knock-on effect on other animals that rely on these creatures for food.
• Human health: Pollution can also make people sick. This is especially true if people drink or come into contact with contaminated water. Contaminated water can cause a variety of health problems, including diarrhea, cholera, typhoid, and hepatitis A.
• Agricultural productivity: Pollution can also damage crops and livestock. This can lead to lower crop yields and make it more difficult to raise livestock. This can have a significant impact on the agricultural sector, which is a major source of income for many people in Andhra Pradesh.

It is important to take steps to reduce pollution from industrial and domestic sources. This can be done by implementing pollution control measures, such as installing filters on factories and sewage treatment plants. It is also important to raise awareness about the dangers of pollution and encourage people to take steps to reduce their own impact on the environment.
