It is true that water resources in India have been depleting very fast. The factors responsible are:

• Over-use of groundwater for irrigation has led to decline in groundwater table in certain regions. Withdrawals has increased concentration of other chemicals like fluoride and arsenic.

• Increasing population means per-capita availability of water is dwindling day-by-day.

• Available water resources are getting polluted with industrial, agricultural and domestic effluents.
