Abstract:
The current study intends to examine quality of groundwater, based on mapping of two coastal blocks in Pudukkottai district, Tamil Nadu. During March 2020, around twenty-nine groundwater samples were collected from the coastal blocks, namely Avudaiyarkoil (15 Nos) and Manalmelkudi (14 Nos). The groundwater samples were analysed for physio-chemical (pH and EC), chemical properties (Ca, Mg, Na, K, CO3, HCO3, Cl and SO4) and calculated the derived properties (SAR and RSC). The physio-chemical properties viz., pH and EC were ranged from 7.7 to 8.62 and 0.54 to 78.25 dS m-1 respectively. The Sodium Adsorption Ratio (SAR) varied from 4.46 to 44.61 m mol/l and the Residual Sodium Carbonate (RSC) varied from nil to 13.67 meq L-1. As per the CSSRI, Karnal Water Quality Classification in coastal blocks of Pudukkottai district, In Avudaiyarkoil block detected good quality water (13.33%) saline water (40%) and alkali water (46.67%) and in Manamelkudi block detected the good quality water 21.46% saline water (42.84%) and alkali water (35.7%) were found. The Geographic Information System (GIS) is used to analyse the spatial distribution of water quality. GIS was used to create a spatial distribution map of these groundwater quality data, which was compared with CSSRI water quality categorization. The resulting map depicts the Avudaiyarkoil and Manamelkudi groundwater quality maps.
