Answer 2

Explanation:

Three measures to control River pollution:

1. Sewage treatment and prevent mixing with river water:  Proper treatment of the household water in order to become safe environmentally. Adequate care can be considered so that water does not get contaminated and gets mixed with the environment. Human and animal waste need to be prevented from mixing through multiple sources. Solution includes construction of pit toilets and sewage treatments in proper manner.

2. Treatment of waste before discharging in river: Factories need to treat the effluent wastes before discharge. Toxic material need to be treated chemically and transformed into material harmless to environment. Finally, factories can try to recycle wastewater.

3. Public Awareness: People need to be aware regarding the effects of water pollution. Voluntary organizations can preach from door-to-door about environmental issues. Students can advocate regarding health education
