What are sources of water pollution and wastewater generation scenario?

It is estimated that 75{b9cca8aede1995d450ecbb7cabdd9c806c66ba8f7afe5985dcdbcb8cb5055004} to 80{b9cca8aede1995d450ecbb7cabdd9c806c66ba8f7afe5985dcdbcb8cb5055004} of water pollution by volume is caused by domestic sewage. The major industries causing water pollution include: distilleries, sugar, textile, electroplating, pesticides, pharmaceuticals, pulp & paper mills, tanneries, dyes and dye intermediates, petro-chemicals, steel plants etc. Non-point sources such as fertilizer and pesticide run-offs in rural areas also cause pollution. Only 60{b9cca8aede1995d450ecbb7cabdd9c806c66ba8f7afe5985dcdbcb8cb5055004} of chemical fertilizers are utilized in soils and the balance is leached into soil polluting the ground water. Excess phosphate run-off leads to eutrophication in lakes and water bodies.
