Guided Notes
Key concepts students will learn:
- •
Point source pollution comes from a single, identifiable source, such as a pipe, while non-point source pollution comes from diffuse sources, like agricultural runoff.
- •
Wastewater, which includes animal and human waste, is a major water pollutant that can be measured by its biochemical oxygen demand or BOD.
- •
High levels of nutrients from wastewater can cause eutrophication, leading to algal blooms that create dead zones when the algae decompose and deplete oxygen.
