Analysis of Water Quality Based on Total Dissolved Solids along the Coastal Area of Kanyakumari, Tamil Nadu

To ascertain the suitability of groundwaters for any purpose, it is essential to classify them depending upon their hydrochemical properties based on their TDS values. The groundwater of the area is freshwater except a few samples representing brackish water at Manakudi. Most of the groundwater samples are within the maximum permissible limit for drinking as per the WHO international standards. At the junction point, where Palayar and sea joins, the Echori effect was also studied and there is no such effect which affect the surface and groundwater properties. The TDS value of 2/ 3rd of the basin is below 500 mg/L indicating low content of chloride in groundwaters which can be used for drinking without any risk.
