Which pollutant or pollutants are most likely to create eutrophic areas?

Which of the following will result in accelerated eutrophication when?

Causes of accelerated eutrophication: Runoff of fertilizers from the nearby field to the water body causes algal bloom which leads to eutrophication. Sewage and industrial effluents increase the temperature and BOD of the water body, thereby causing increased biological activity, leading to algal blooms.

Which US legislation empowers the EPA?
