Evaluating Groundwater Quality in Makassar Using Cl/EC Diagrams: Insights into Saline Intrusion and Contamination
Abstract
Groundwater in the Makassar coastal region is at risk due to natural and anthropogenic factors such as seawater intrusion and pollution. By employing Chloride (Cl) concentration and Electrical Conductivity (EC) measurements, this study aims to classify groundwater types and assess the extent of saline intrusion. The analysis, based on Cl/EC diagrams, identifies key areas affected by seawater intrusion and offers insights into sustainable groundwater management practices. Samples collected from various locations show different degrees of contamination, ranging from normal freshwater conditions to severe seawater intrusion. The study provides recommendations for managing groundwater resources to prevent further degradation.
