HYDROCHEMICAL APPRAISAL OF GROUNDWATER IN CHINTAMANI TALUK -A CASE STUDY

Abstract

. Out of eight ground water samples six samples were found to have nitrate level above the permissible limit (45mg\L), all the fluoride levels close to the permissible limit (1.5 mg\L). Six samples were found to have Pb level greater than the permissible limit (0.01 mg\L). The above mentioned water quality variables are hazardous to the biological system which emphasises the need for improvising the water quality.

Their theories have indicated the origin of the first life forms in water, from inorganic molecules through polymerization. Water became the primary medium for the birth of life on earth three million years ago. When we look at the present scenario, we must realize that the water quality is deteriorating due to several factors such as urbanization, industrialization, etc. As our earth is a closed system, the quantity of water has remained the same over billions of years but most of the fresh water is in the form of glaciers and only about 1% of it is available as potable water which is largely stored beneath the surface in Aquifers. As agriculture is the backbone of our nation, groundwater is the major source of irrigation in many parts of Indi
