Abstract
Wetlands deliver many ecosystem services but are under continuous threat due to various anthropogenic activities. The present study has been carried out to examine the suitability of Kusheshwar-Asthan wetland�s water for agriculture. A total of 57 water samples were analyzed for various water quality parameters like electrical conductivity, pH, temperature, dissolved oxygen (DO), major cations (Ca2�, Mg2�, Na�, K�), and major anions (PO43�, SO42-, N-NO3-, Cl-, HCO3-). Overall, the water of the wetland was found to be alkaline. The pre-monsoon samples had a relatively higher concentration in most of analyzed parameters except for pH, DO, NO3-, PO43- and Cl-. The concentration of cations follows the order of Na� . Ca2� . Mg2� . K� in both seasons and for anions it is HCO3- . SO42- . Cl- . NO3- . PO43- for pre-monsoon and HCO3- . Cl- . SO42- . NO3- . PO43- for post-monsoon. According to Piper diagram and Durov plot, Na-K-HCO3 was the major hydro chemical facies of the surface water. The various irrigation quality parameters showed that wetland water can be categorized as good to excellent quality. As a result, this finding can aid in the long-term sustainable use of the wetland water with regulated anthropogenic interventions. The study will be beneficial in designing long-term extensive management plans for the conservation of the wetland. � 2022 The Authors.
