Abstract: Surface water resources have played an important role in the development of human civilization. Surface water and sediment samples were collected during pre-monsoon and monsoon seasons for the determination of physicochemical parameters. Parameters were determined using standard methods. The study report discusses about the analysis of various physico-chemical parameters of TDS, DO, turbidity, pH, Temperature, Alkalinity, Nitrate, Phosphate, Chloride, Sulphate, Organic Carbon, Total Nitrogen, Total Phosphorous and Textural Analysis of surface water and sediments collected from different months of Paraikulam pond were measured during June 2024-September 2024.(Monsoon Period) and February 2025-May 2025 (Pre-Monsoon Period). The present results reveal that the values of most physical and chemical parameters where higher in pre-monsoon period compared to monsoon period. Sediment pH was more acidic in Pre-monsoon season compared to monsoon season. Organic Carbon, Phosphorous, Nitrogen contents of sediment increased during Monsoon season. Changes in water and sediment chemistry might be responsible for the variations in the physical and chemical properties.

Keywords: physico-chemical characteristics; water; sediment.
