Analysing the Surface Water Class and Correlation Study of Pond Water

Abstract

The water resources are most significant for the natural ecosystem and human improvement. Kanchipuram has many legendary temples, climatic variation and urbanisation cause a reduction in the temple pond water level. The water quality study of seventeen historical temple ponds was done. The subsequent parameters, pH, electrical conductivity, dissolved oxygen, total dissolved solids, total hardness, total nitrogen, total phosphate, and the biological parameter, total coliform count, have been measured. The research work was done in the periods of 2017, 2018, 2019, and 2020. The results were compared with ISI-IS: 2296-1982 class A, B, C, D, and E standards for surface water. The pH value was greater in the minimum temple pond water; the other parameters were within the limit compared with the class B, C, D, and E standards. Analysing the results exposed temple pond water useful for bathing, swimming, fish culture, irrigation, etc. The pond water is useful for drinking purposes after purification. Correlation analysis shows total dissolved solids have a good correlation with electrical conductivity (r=1) in four years. Conservation and renovation are important for maintaining the ponds in good condition in the future.
