Which statement best explains how the Aswan High Dam contributes to pollution?

Fumes from the dam's hydroelectric power plant affect the air quality.

Waste and chemicals flow from the dam and result in ground pollution.

The dam cannot control flooding, which leads to water pollution along the river.

The dam affects the soil, which causes farmers to use fertilizers that create pollution.

The Aswan High Dam basically made Egyptian economy rich and industrialized. However, the massive dam contributed to additional pollution. The dam stopped the deposition of nutrient rich silt in Egyptian farms, forcing farmers to use more fertilizers. More fertilizers caused the soil to become more saline, and the resulting runoff polluted the waterway and caused increased growth of algae.
