Water source have always been a precious commodity for human life. Groundwater is used for domestic supply, industries and agriculture in most parts of the world. The Geochemical characteristics were carryout in the Siruthalaikadu creek which is situated in the southeast coast of India in the Tamil Nadu state. It is located at about 370 km south of Chennai and 75km south of Karaikal, Nagapattinam district, Tamil Nadu, and falls between latitude 10°20'56" to 10°18'51"N and longitudes 79°46'48" to 79°47'24"E. It is included in the survey of India toposheet number 58 M/14 on 1:50000 scale. It is an estuarine marshy environment situated in the Muthupet mangrove region. In this study 6 ground water samples were collected and the Physical parameters such pH, EC, TDS and Major cations (Ca2+, Mg2+, Na2+, K+) and Anions (HCO3-, Cl2-, SO4) were analyzed. Analytical shows that the water in wetland region is generally alkaline with pH ranging from 8.25 to 9.16 with an average of 8.71. Electrical Conductivity (EC) ranges from 6809 to 15830 µs/cm with an average of 9585.5 µs/cm. Total dissolved solids (TDS) were also shows higher concentration and ranges from 2879 to 8140 with an average of 4763. The Cl ranging from 1755 mg/l to 2431 mg/l with an average of 1919.8 mg/l. Chloride is the dominant anion followed by SO4. Higher concentration of chloride in this region is due to mixing of sea water. Sodium ranges from 723.2 mg/1 to 936 mg/l with an average of 827.5 mg/l and is the important and most abundant alkali metal which is highly mobile and soluble in water.
