Chennai Ground Water
Groundwater meets unknown but significant quantity of urban domestic water needs, especially the middle and lower economic sections of the society. Today, cities and towns with their growing population, vertical growth, widening demand – water supply gap and fluctuations of annual monsoon, is subjected to seasonal water stress. This has prompted drilling more borewells, that increased groundwater extraction, which however eventually lead to poor yields. Over exploitation not only decline bore well yields and leave open wells dry, but can also decrease the quality of groundwater. Groundwater in Chennai is one typical example.
Most scientific data on natural resources available today are largely from State or Central government agencies and are not in a readily usable form. But areas such as weather, agriculture, and health that have embraced digital tools are popular today.
However, in some disciplines infusion of current technologies are yet to make an impact. Groundwater and water quality are one such area today.
Some information on Chennai groundwater and its quality available in literature will be shared below for the general public.
