Quizplus · Accepted Answer

Sewage contains high levels of nitrogen and phosphorus, which can lead to eutrophication in bodies of water. This process can cause excessive algae growth, decreased oxygen levels, and harm to aquatic life. Sodium chloride, carbon dioxide, nitrogen, and phosphorus are all naturally occurring compounds that can be found in water, but sewage specifically contributes to an excess of nitrogen and phosphorus. Human wastes and heavy metals may also be present in sewage, but are not the primary concern related to water pollution. Soil and microorganisms may also be present in sewage, but in smaller quantities compared to the nitrogen and phosphorus compounds.
