A Study of Salinity of ground water in some semi-arid tracts in Vadagam Taluka, Banaskantha District of Gujarat

Abstract

Because of the insufficiency of water resources and serious environment, it becomes much more mergence to develop the water saving agriculture The northern part of Gujarat state may be classified as a semi-arid region because most of the area receiving low rainfall. About fifty samples of ground water were collected from different tracts in Vadagam regions during pre-monsoon 2018, post-monsoon 2018 and pre-monsoon 2019 and tested for their EC and P^H values. These water samples were further tested for cations and anions. The data obtain were used for classification of water into different categories on the basis of EC (Electrical Conductivity).In general it was found that there was no area having EC within 250 micro mhos/cm in ground water during year 2018-19. Thus, the water quality has improved during pre-monsoon 2019, as compared to pre-monsoon 2018 due to the recharging of ground water by rainfall in year 2018.

Key words: Water Analysis, Salinity, Electrical Conductivity.
