Abstract

Saltwater intrusion is a global issue that affects the coastal areas worldwide. Due to this intrusion it will affects the growth of crops, soil fertility and human health. Current study estimates parameters such as Water Quality Index(WQI), Human Health Risk Assessment(HHRA), Seawater Mixing Index(SMI) and Irrigation efficiency(IE) in order to examine the ground water quality of Kanchipuram district, Tamil Nadu coastal area. A total of 60 sampling stations were taken to examine ground water quality. For the ground water analysis the physicochemical parameters were taken into the account. Q-GIS have been used in mapping the sampling locations and affected areas. For WQI out of 60 stations, it was observed that around 30% of groundwater is above good quality and around 42% is very poor and not suitable for consumption. The WQI states that groundwater in Kanchipuram district was moderately polluted. SMI was also calculated, it was observed that out of 60 stations SMI values of 23 stations were above 1 i.e, in 38% of stations SMI value was observed to be high. Also calculated HHRA, it was observed in 13 % of stations fluoride content is greater than 1 in children. The analysis shows that children's average fluoride content is higher than adults. Irrigation Indices concludes that 65% of sampling stations  having SAR values greater than 10 mEq/L  and 58 stations having Na% less than 80 percent.
