Abstract

The aim of this study was to assess the open pond and groundwater quality of Tiruchirapalli city of Tamil Nadu, India. The groundwater quality viz., pH, electrical conductivity, total hardness, calcium ion, magnesium ion, chloride, carbonate, bicarbonate, inorganic nitrate, nitrite, phosphate, ammonia and reactive silicate were analysed with respect to various seasons and recorded in the range of 7.1 to 8.1, 97.67 to 533.67 mhos cm-1, 7.07 to 186 mg l-1, 4.67 and 112.0 mg l-1, 2.40 to 92.80 mg l-1, 15.23 to 661.73 mg l-1, 60 to 480 mg l-1, 22.7 to 544.9 mg l-1, 15.33 to 68.00 mg l-1, 0.001 to 0.480 mg l-1, 0.01 to 0.42 mg l-1, 0.02 to 0.75 mg l-1 and 1.1 to 2.96 mg l-1?respectively. The present findings concluded that the quality of ground waters can be considered suitable for human consumption. But the pond water available in and around Tiruchirappalli city was not fit for human usage, agricultural or industrial purposes.
