What describes untreated human waste entering water bodies?

Explanation:
Untreated human waste entering water bodies is called raw sewage. Raw sewage refers to domestic wastewater that has not undergone any treatment, meaning it still contains solid waste, human waste, bacteria, viruses, nutrients, and other contaminants. When discharged directly into rivers, lakes, or seas, it poses serious health risks and ecological problems, including the spread of disease and oxygen depletion from microbial activity. This differs from treated sewage, where some or most solids and contaminants have been removed, and from concepts like saltwater intrusion, which is about seawater moving into freshwater supplies, not about waste entering surfaces.
