Water pollution and eutrophication — Homework
Show the percent-decrease calculation for every dissolved oxygen question.
- 1.Dissolved oxygen reads 10 mg/L upstream and 4 mg/L downstream of a nutrient input. Calculate the percent decrease.
- 2.Classify as point-source or nonpoint-source: fertilizer washing off a golf course; a factory's single discharge pipe.
- 3.Put the eutrophication sequence in order: decomposition consumes oxygen, algae die, nutrient runoff, algal bloom.
- 4.Describe your water clarity test (or your comparison of two described clarity readings) and what it suggested about the water body's condition.
