Abstract

One of the research areas to determine the phenomenon of seawater intrusion through analysis of the physical and chemical characteristics of groundwater is in the Coastal area of ​​Hunuth Village, Teluk Ambon District, Ambon City, Maluku. The coastal community of Hunuth Village utilizes groundwater to meet their daily water needs. However, due to the existence of residential areas close to the coast, the groundwater in this area has been polluted or intruded by sea water.The results showed that groundwater with high pH values ​​was shown in areas far from the shoreline (northern part of the study area), while high TDS, salinity and DHL values ​​were generally found in groundwater samples close to the shoreline. The groundwater facies in the study area show the types of Ca-HCO3 (calcium and bicarbonate), types of Na-HCO3 (sodium and bicarbonate), and types of Na-Cl (sodium and chloride). Areas close to the shoreline have experienced seawater intrusion as indicated by DHL values ​​> 229.25 mho/cm, Cl/HCO3 ratio values ​​which are generally > 2.80 meq/l, and groundwater facies with the type of Na-Cl (sodium and sodium chloride). Therefore, it is necessary to treat water before it is used as drinking water, buy bottled drinking water or use the services of a water company for polluted wells, and build a dam in the northern part of the study area which has a flat topography. trees to retain water, so that fresh water can easily push salt water into groundwater aquifers in the study area.

Abstract

One of the environmental problems often faced by residents in coastal areas is sea water intrusion. The research area is a coastal area so it is very possible for seawater intrusion to occur. This study aimed to determine the hydrogeological system of the research area, and to compare the stretch of intrusion in Airlouw and Erie Village using physical-chemical parameters of groundwater through wells owned by local residents. The research area geology is dominated by Ambon volcanic rocks units, ultramafic rocks and coral limestones. The aquifer system in the study area is an highly to moderately productive aquifers. The lithology that becomes the aquifer is igneous rock in the form of weathering of Ambon volcanic rocks. The results of a comparative study in the research area, based on physical-chemical parameters which include pH, salinity, DHL and TDS values in the: (a) Airlouw Village is characterized as brackish water; whereas (b) Erie Village is characterized as fresh water. Based on the comparison of DO value shows that: (a) Airlouw Village is generally moderately polluted except for SB3 (DO>6.5); whereas (b) Erie Village is not polluted except P6 is moderately polluted (DO:2.0-4.4). Groundwater on: (a) Airlouw Village shows Cl+SO4 facies which indicates of seawater intrusion; whereas (b) Erie Village shows that the Ca-Mg-HCO3 facies has no indicates of seawater intrusion.
