Abstract
Water is essential for livestock consumption, drinking, agriculture, and aquaculture. Pond and river are considered to be self-contained, landlocked ecosystems that are often teeming with rich vegetation and diverse organismal life. Groundwater is also involved with drinking and irrigation. Water contains different organic and inorganic components. The water samples were investigated for Mg, pH, Na, EC, Ca, K, S, and P ion at Rajoir Upazila on Madaripur district in Bangladesh to know the water quality of this Upazila for various uses from November 2020 to October 2022. During the study period, Surface water (pond water) had an average pH higher than that of river and tube-well water. The average pH of Pond water was 7.54 at Bajitpur and Raajoir Union. The present research also showed the Electrical Conductivity (EC) ranged from 280 to 1451.67 μScm-1. For irrigation, the Sodium Absorption Ratio (SAR) is the key feature. River water had the lowest SAR (0.567) and Groundwater had the highest (8.67 MeL-1). Groundwater had the highest SSP value (88.9%), while river water had the lowest (24.8%). Almost all the ground and surface (pond and river) water samples were slightly alkaline and appropriate for drinking, irrigation, livestock farming, and aquaculture.
