摘要：The present study was aimed to analyze the groundwater quality for the irrigation purpose at Cheddipalayam in Batticaloa District. Groundwater samples were collected at three different distances such as 100m, 200m and 300m from seashore. Water quality parameters such as pH, electrical conductivity (EC), total dissolved solids (TDS), Ca2+, Mg2+, Na, sodium adsorption ratio(SAR) and Ca2+/Mg2+ ratio were analyzed. The study revealed that pH, Ca2+, Mg2+, Na, SAR and Ca2+/Mg2+ ratio values were found within permissible limit for irrigation while EC and TDS were in high range. The pH ranged from 7.23 -8.41 while EC and TDS ranged from 1.18 1.60dS/m and 732 1065mg/l respectively. Concentration of Ca2+, Mg2+ and Na+ varied from 6.17 - 8.12meq/l, 1.76 2.53meq/l and 2.30-3.21meq/l respectively. The pH decreased slightly with distance from seashore while EC, TDS and Na increased slightly with distance. Even though EC and TDS exceed the desirable limits, this groundwater can be used for irrigation purpose with the suitable management practices against salinity.
