As a part …
Ground water samples from 83 villages in Honnali taluk of Davangere district were analyzed for their suitability for irrigation purpose with special reference to presence of fluoride content. Ground water in the study area was classified according to sodium adsorption ratio and electrical conductivity.
The aim of the present study is to assess the quality of the 64 ground water samples at the top, foot and in the land area which stretches about 4 kms in the south of the Kolli hills. The physico-chemical parameters namely pH, EC, TDS, PA, TA, CH, MH, TH …
