The distribution patterns mapping of seawater intrusion in Kendari City, Southeast Sulawesi Province

Abstract

The main purpose of this research is to determine the distribution pattern of seawater intrusion in Kendari City, Southeast Province by using direct observation method by measuring the value of electrical conductivity (EC). The electrical conductivity measurement was done at 140 points of groundwater wells owned by the communities. The EC result of electrical conductivity value varies and categorized in five groups that are: 541-2,650 μS/cm, 400-520 μS/cm, 240-374.4 μS/cm, and 208-224.4 μS/cm. Based on the EC values, indicated that several areas in Kendari City have experienced with high water sea intrusion within the region Tondunggeu, Puday, Kasilampe, Mata and Purirano with electrical conductivity values range from 541 μS/cm to 2,650 μS/cm.
