Abstract
- Point source pollution is a widespread problem that can impact our water sources. In contrast to categories of pollution for which we may not know the source or cause, point source pollution can be traced back to its point of origin, such as a specific industry or sewer system. Phosphate is a type of point source pollution that contributes to eutrophication and can cause algal blooms that harm marine life and threaten clean drinking water. In this lesson, students will learn about phosphate pollutants by solving a mystery by analyzing well water data to determine the cause of a devastating fish kill.
