Every source of water can be subject to pollution. In the case of underground water, polluted surface water can enter the saturation zone of an aquifer and so lead to its contamination. Pollution can come from waste tip leachate containing heavy metals and organic compounds, farm run-off containing nitrates and pesticides, from industrial wastes and from contaminated land. River water can be affected by farm drainage, sewage works, industrial effluents and run-off water from roads. There is a clear need to maintain the quality of the aquatic environment to ensure that the available water is suitable for treatment for public supply, and that the cost of treatment is kept as low as possible.
