Abstract

The present study deals with the physico-chemical analysis of ground water samples collected from Thovalai, Agastheeswarm Vilavancode and Kalkulam taluks of Kanyakumari District, Tamilnadu. Available literature on physico-chemical parameters were meager. Therefore, to fill the gap the present study was carried out to evaluate the ground water quality for human consumption. Physical characteristics like turbidity, total dissolved solids, electrical conductivity, chemical factors like pH, alkalinity, total hardness, alkali and heavy metals like calcium, magnesium, sodium, potassium, iron, manganese, and free ions such as nitrate, fluoride, sulfate and phosphate were analysed following standard methods of APHA and results were compared with WHO standards. Among the parameters turbidity values were higher in all the four taluks viz. Thovalai 8 NTU, Agastheeswarm 9 NTU, Kalkulam 17 NTU, and Vilavancode 18 NTU these results were higher than the WHO standards of 5 NTU. Higher turbidity often promotes growth of harmful bacteria and protect the bacteria from disinfection. Excluding turbidity the quality of ground water is highly acceptable in almost all taluks of Kanyakumari District. Protecting natural resources of water and checking for standards is generally good for human beings, domesticated and non-domesticated animals.
