Abstract: Abstract Monitoring and mapping physicochemical properties of springs water are very crucial in Upper Kosi watershed as natural springs, and spring-fed streams are the only source of drinking water for thousands of inhabitants living there. Understanding of hydro-geochemical characteristics and water quality of the springs in perched aquifers of the basin provides useful information for sustainable use of spring's water with climate change scenarios. For this purpose, a total of 65 springs were inspected and investigated for their significant particle scenario to evaluate their water quality, potential origins, and hydro-chemical evolution. Groundwater samples were collected from springs under consideration and are examined for an aggregate of 14 water quality physicochemical parameters during pre- and post-monsoon season. Two types of hydro-chemical complexions were observed during pre-monsoon sample analysis. One is Ca–Mg–HCO3−, and the other is a mixed Ca–Mg–Cl−paradigm. It perceived that hydro-chemical facies Ca–Mg–Cl− was shifted into Ca–Mg–HCO3− in post-monsoon. Higher deviation in turbidity, magnesium, and sulphate indicated that geochemistry of the study area is not homogenous. A significant degree of seasonal variations in the concentration water quality parameters like pH, Cl−, F−, SO42− K+, total alkalinity, and bicarbonate was analysed using one way ANOVA (p ≤ 0.05). As per concern of quality, groundwater emanating from these springs is apposite for drinking as per drinking water specifications provided by the Bureau of Indian Standards (IS 10500:2012).
