Solution
-
Sewage is the wastewater that is released from homes, industries, offices, and other sources.
-
It is the liquid waste from domestic activities. Most of it is water, which has dissolved and suspended impurities.
-
Sewage is a major source of plant nutrients, mainly nitrates and phosphates.
-
Excess nitrates and phosphates in water promote the growth of algae, sometimes causing unusually dense and rapid growths known as algal blooms.
-
This can eventually result in eutrophic dead zones where aquatic life cannot survive because of a lack of oxygen.
