The present work focused on the seasonal variations in the physico-chemical parameters of the Gudlavalleru engineering college pond at Krishna district Andhra Pradesh during summer and winter season. Pond is found outside the college and college management imposes restrictions over misuse of the pond, therefore they remain comparatively clean. Total nineteen parameters were analysed and their seasonal variation was discussed. The correlation matrix of various physico-chemical parameters are computed and analysed. There is a relationship among the ecologists and microplanners about the importance for conservation of ponds as sustainable source of water in rural communities. A wide variety of inorganic toxic substances may be found in the water pond is very small or trace amounts. Even in trace amounts, they can be danger to public health. Some toxic substances occur from the natural sources but many others occur due to industrial activities and/or improper management of hazardous waste. Results of the present study indicated that the mean values of temperature, pH and total alkalinity were highest in summer season and lowest in winter season.
