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