摘要：

Urbanization in India results in a population increase and other infrastructure developments leading to a large demand for water. For Delhi, the demands for water and population growth have increased exponentially, whereas water availability (surface and groundwater) has decreased resulting in an increase in tube well-irrigated areas. Thus, during the last 25 years, over exploitation of groundwater for industrial, domestic and irrigation purposes has occurred. The annual rainfall and associated groundwater recharge has been below normal during this period. Composite groundwater samples from 250 cased wells in villages adjacent to Delhi were collected during 1998 and compared to earlier published data. The spatial variations in anions, cations and micronutrients indicate that water quality has deteriorated in the west and northwestern parts of the city.
