Abstract: Block wise categorization of groundwater quality in coastal region of Thoothukudi district was undertaken during November 2018 for its optimal usage. A total of 82 ground water samples representing different coastal blocks viz., Ottapidaram (12 samples), Thoothukudi (10 samples), Srivaikuntam (8 samples), Alwarthirunagari (14 samples), Thiruchendur (17 samples), Udangudi (13 samples), Vilathikulam (7 samples) were collected, analyzed for quality parameter and categorized into different water quality as per the standard procedure. The investigation revealed that groundwater samples with respect to pH and EC ranged from 6.90 to 8.87 and 0.13 to 11.9 dS m-1 respectively. Residual Sodium Carbonate (RSC) varied from Nil to 18.00 meq L-1 and Sodium Adsorption Ratio (SAR) ranged from 0.01 and 31.71 based on the CSSRI, Karnal water quality classification. The good quality water distribution in different blocks of Thoothukudi district were in the order of Ottapidaram (84.6 %), Srivaikuntam (75%), Alwarthirunagari (71.4%), Vilathikulam (57.1%), Thiruchendur (52.9%), Udangudi (46.1%), Thoothukudi (30%). Overall in Thoothukudi district, 59.58 per cent of groundwater samples were in good quality, Saline water (28.75%) distributed in the blocks of Ottapidaram, Alwarthirunagari, Thiruchendur, Srivaikuntam, Thoothukudi, Vilathikulam and Udangudi. Alkali water found in Ottapidaram, Thoothukudi, Alwarthirunagari, Thiruchendur block to the extent of 11.64 per cent.
