Option C: Introducing sewage in water systems increases the concentration of solids.
Sewage is one of the most concerning sources of water pollution. Sewage, in simple terms, is the wastewater that contains compostable materials from the kitchen, industries, bathrooms, etc.
When untreated sewage is introduced into the water bodies, the microorganisms in it take up the oxygen from water for their aerobic respiration. As a result, the resident organisms of the water body have to struggle to survive due to the lack of oxygen in the water.
Sewage also contributes to the eutrophication of water bodies. Eutrophication is the process by which the nutritional elements, like phosphates and nitrates, in a water body, are enhanced causing the microorganisms to feast over them.
Sewage has some solid particles that can't be dissolved or decomposed. This then leads to the concentration of solids at the base of the water body. This further leads to the growth of various organisms using dissolved oxygen and leads to the deterioration of water quality.
