Question

Environmental Engineering

Did the water from the pond sample have phosphate and/or nitrate levels that might put it at risk for eutrophication and subsequent algal blooms? Explain your reasoning.

Answer 1

As nitrate and phosphate level in the pond gets increased above than a certain level, then these excessive nutrients cause algal and plankton abnormous growth. These enormous phytoplankton and algal consumes too much oxygen from the pond, and these organisms when die they also consumes too much oxygen which ultimately lead to death of pond lives. These nutrients such as nitrate and phosphate are provided to pond by the human activities ( generally detergents, fertilizer etc causes nutrients).

so obviously we should treat our sewage before disposal, if untreated it might be a risk of eutrophication and algal bloom.
