The effects of water pollution are many, here are just a few of them:

· WATER POISONING:
PCB's (polychlorinated biphenyls), chloroform, and pesticides have been found in some municipal drinking water supplies. Sccientists are concerned that drinking even a small quantities of these substances over many years may have harmful affects.

· RECREATIONAL EFFECTS:
Recreational effects that water pollution has prevent people from using and enjoying water due to odors and floating debris, which make boating and swimming unpleasant. And the risk of diseases make polluted water unsafe.

· PROCESS DISTURBANCES:
Processes in water which use the oxygen in water help to make the wastes harmless. In Mineralization aerobic bacteria break down organic wastes into simpler substances. Some of those substances (Phosphates and Nitrates) serve as nutrients (food) for plants. Aerobic bacteria uses oxygen in water when breaking down organic wastes. Scientists can find out how much organic matter the water contains by measuring how much oxygen the bacteria use when breaking it down. If the water contains too much organic wastes, the bacteria will use up most or all of the oxygen in it. Some species of game fish such as salmon, sturgeon, trout, and whitefish will be unable to live in the water. If all the oxygen is used, most aquaticlife will be unable to survive.
