The attempt is made along the Cheyyar river basin, Kancheepuram district. The total sample collected along study area is 20. The physio-chemical parameters were tested. The pH are ranges from 6.5-8.1 and they are neutral. The other values such as EC, TDS, Turbidity, Total hardness are within the permissible limit comparing the standard specification. The chemical parameter such as calcium, magnesium value 75% within the permissible limit as specified in standard. The bicarbonate has high value, sodium, chloride and other parameters are as follows. The order of abundance of chemical concentration is Na+ > Ca2+> Mg2+> K+ = HCO3−> Cl− > So4. The type of water present in the study area is Ca-Mg-So4 type, Ca-Mg-HCO3 type and Ca-Mg-Cl-So4 type. The Ground water qualities are compared with the Indian Standard and World Health Organization (WHO). The SAR value of the samples ranges from 0.825 to 7.829 (meq/L), Sodium percentage value ranges from 20.376 to 65.007(meq/L) .Then comparing SAR 65% is suitable and by sodium percentage 72.45% of water is suitable for the agriculture.
