Physicochemical characteristics of water are key criterion for determine the quality of water. In Pali the Lakhotiya Talab is main surface water source, while ground water is also broadly use. In the present investigation carried out to determine the physicochemical parameters such as pH, electrical conductivity, hardness, alkalinity, chloride, sulphate, nitrate, and calcium. The findings reveal that water samples of the Lakhotiya Talab showed pH moderately alkaline, while electrical conductance, hardness, showed low means the samples of groundwater fluoride, ferrous, nitrate and phosphate showed higher means value during both pre monsoon and post monsoon samples but  higher mean value during post monsoon period. It found that during post monsoon season samples of both surface and groundwater was more mean value than pre monsoon season, and groundwater more polluted at many fronts than surface water. Based on these results, it recommended that surface and groundwater samples in the study are should tested before use for its portability and other domestic or industrial uses.
