What can be possible impacts of consumption of contaminated/unclean water on the people?
The consumption of contaminated or unclean water can have serious impacts on people. When water gets polluted by foreign matters such as micro-organisms, chemicals, industrial and other wastes, it deteriorates the quality of water and renders it unfit for human use.
Such contaminated water contains toxic substances that get dissolved or lie suspended in water. When people consume this water, it can lead to various health problems as the pollutants enter the human body. The presence of agricultural effluents like fertilizers and insecticides, domestic wastes, and industrial effluents makes water harmful for consumption.
Additionally, the context indicates that water resources are degrading rapidly and the availability of usable water is being limited due to pollution. This creates a situation where people may be forced to consume poor quality water, further affecting their health and well-being.
Explanation
The textbook context explains how water gets polluted by various foreign matters and becomes unfit for human use. While the context doesn't explicitly list specific diseases, it clearly establishes that contaminated water contains harmful substances like micro-organisms, chemicals, and industrial wastes that deteriorate water quality. The key point is that such water is rendered 'unfit for human use,' implying adverse health impacts on consumers.
