Abstract:
Groundwater quality is important as it is the main factor for determining its suitability for drinking, domestic, agricultural and industrial purpose. In April 2021, a block wise categorization of groundwater quality in the Viluppuram district's coastal region was taken to ensure its optimal use. A number of 23 water samples were obtained for this study, representing the different blocks viz., Marakkanam (11), Vanur (12) and 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 ranged from 7.0 to 8.4 with mean of 7.7 and EC ranged from 0.27 to 4.35 dSm-1 with mean of 1.14 dSm-1 respectively. Residual Sodium Carbonate (RSC) varied from nil to 11.10 meq L-1 and Sodium Absorption Ratio (SAR) ranged from 0.26 to 20.31 with a mean SAR of 0.93. In the coastal blocks surveyed, the frequency of good quality water was more in Marakkanam block based on the CSSRI, Karnal water quality classification. The Vanur blocks have the highest alkalinity (75%) and the lowest alkalinity was found in Marakkanam block (63.63%).
