  • Abstract

    In the present investigation, groundwater samples were collected from 12 places in Tiruchendur coastal area, Tamilnadu, India. Physicochemical parameters such as pH, alkalinity, electrical conductivity, hardness, total dissolved solids, dissolved oxygen, COD, BOD, sulphate, fluoride, nitrate and trace metals like chromium, zinc, copper, iron, lead, manganese and cadmium were analyzed. Standard methods were followed for the analysis of physicochemical parameters. The trace metals were analyzed in Atomic Absorption Spectrophotometer (AAS). The results were compared with WHO, ICMR, IS. The physicochemical parameters for some samples showed that the values are deviating from the set limits for the domestic purposes. The trace metal analyses are not on the exceeding side of the permissible limit in all the samples. So the trace metal values arouse no concern at present. The water quality in all the areas surveyed was found to be unfit for human consumption. Because of lack of water quality, different diseases frequently affect local people. Hence, suitable water quality management is essential to avoid contamination.
