Question

Quizplus · Accepted Answer

Sewage contains nutrients that, if released into bodies of water untreated, can cause eutrophication, a process in which an excessive amount of organic matter leads to oxygen depletion and the growth of harmful algal blooms or dead zones. Sewage treatment removes these nutrients before releasing the water back into the environment, preventing eutrophication.
