Wastewater from chemical factories has been turning the river magenta and
bright orange.
Farmers have even reported animals dying shortly after drinking from the river.
These two problems, overuse and pollution, actually magnify each other.
In many areas, sewage from factories and towns flows directly into the river.
When oil spills occur, the water is coated with a greasy sheen, and ugly yellow
bubbles seem to blister its surface.
When water levels decrease, there is not enough water movement to clear the
pollution, which then builds up in greater and more dangerous concentrations.
