Abstract
Water resources are under major stress all over the world due to agricultural expansion, damming, diversion of water, over-use, and enumerable types of water pollutants released in the irreplaceable resources in many parts of the globe. The Physico-chemical and biological properties of water determine the quality of water for its suitability for drinking, domestic, fishing, industrial and irrigational purposes. Karjat and Shrigonda tehsils are drought-prone areas of Ahmednagar district. The present study was carried out from July 2022 to May 2024 to estimate water quality in terms of its Physico-chemical parameters from 15 sampling sites which supports enormous biodiversity. The parameters viz. water temperature, pH, electrical conductivity, total dissolved solids, alkalinity, dissolved oxygen, biochemical oxygen demand, chlorides, nitrates, phosphates, calcium hardness, magnesium and total hardness were analyzed and found that, all parameters showed remarkable seasonal variations. Most of the parameters were beyond permissible limits prescribed by IS, BIS, WHO, and ICMR, so water is not suitable for drinking purpose. Some reservoirs are temporary and need to refill during summer every year.
