Shutting down factories that discharge materials to rivers.

Explanation:

Water is one of the main natural assets that humans need to survive. One of the most urgent problems that must be presented soon is access to drinking water, due to the threat that access to fresh water presents today.

One of the main points when controlling the current water pollution in the surface waters of the United States is closing the factories that discharge materials to the rivers. For this point to be achieved, the use of chemical and physical products that pollute, part of which are in factories, must be prohibited. It may not sound so urgent, so it is necessary that these initiatives come from competent authorities that are aware of the danger that these materials can cause to surface waters.

Shutting down factories that discharge materials to river.

Explanation:

Since we all know that water is one of those natural resources which needs  most living animals to survive. River and lakes are the important sources of surface waters so if want to reduce the pollution from the surface water we need to clean our rivers and lakes by not discharging waste into it. since Industrial waste contains many chemicals so they are more hazardous so we need to control it first.
