Why is stopping untreated wastewater important in river conservation?
Answer and explanation
Correct answer: Because it helps maintain river water quality
Untreated wastewater may contain pathogens, organic waste and harmful chemicals. Preventing its discharge, or treating it before discharge, reduces pollution, helps protect dissolved oxygen levels and maintains water quality for aquatic life and human use. Silt deposition mainly increases because of soil erosion and sedimentation, not simply because of untreated wastewater. Exam tip: associate river pollution control with sewage treatment plants.
