Appraisal of water quality of Akot and Balapur Block in Purna tract of Vidarbha region of Maharashtra

Abstract

The present investigation entitled “Appraisal of Water Quality in Akot and Balapur tehsil in Purna Tract of Vidarbha Region” was undertaken during 2018-2020 in Department of Soil Science and Agricultural Chemistry, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra. Fourty water samples from borewell and other sources from Akot and Balapur tehsils of Akola district of Maharashtra consisting of river, farm pond, dam were collected and analyzed for various quality parameters. The irrigation water was having high salinity and low sodium hazard (C3S1) during post monsoon (winter) season, amongst the cations Ca2+, Mg2+ and K+ was within the permissible limit in borewell and other sources of irrigation, except sodium which was above permissible limit in borewell water as well as other sources of irrigation. The all anionic composition in which HCO3- and Cl- was above permissible limit and SO42- were, below permissible limit in post monsoon season. Total dissolved solid in ground water were categorized as permissible to unsuitable. The sodium adsorption ratio was within the permissible limit in post monsoon season, Whereas the adjusted sodium adsorption ratio some samples falls above acceptable range and Mg: Ca ratio all samples during post monsoon (winter) season falls in permissible limit. As per Kelley’s ratio the all samples during post monsoon season was within the permissible limit, except three samples crossed the permissible limit. On the basis of permeability index ground water was fall in class II which categorized as medium during post monsoon season. The residual sodium bicarbonate of all samples during post monsoon were found in above acceptable range. As per magnesium adsorption ratio all samples from both the sources found within the permissible limit during post monsoon season. Soluble sodium percentage of the all ground water samples during post monsoon season from both the sources are unsuitable for irrigation.
