Geochemical Behavior Analysis of Heavy Metal Iron (Fe) Using Remote Sensing Data in Rivers Around Lake Matano

EasyChair Preprint 6640

Abstract

This study aims to determine the contamination of ferrous metal (Fe) contained in river water that empties into Lake Matano, Sorowako, South Sulawesi and is associated with remote sensing analysis. From the geochemical review of the heavy metal content of Fe that has been carried out. River water samples were taken at 10 points in three locations on the river and one location in the resident's bore well. Sampling was carried out in the upstream, middle and downstream sections and one at the resident's well as a comparison. Heavy metal concentrations were determined using Atomic Absorption Spectroscopy (AAS). The concentration of heavy metal Fe in the Salonsa River was 1,02 ppm, in the Lawewu River was 0,78 ppm while in the Incoiro River was 0,68 ppm. The concentration of Fe in the bore well in residential areas is 0,88 ppm. This value is still above the water quality standard. Meanwhile, based on the results of remote sensing analysis, the total land opening value is 44,74 km². The Salonsa River which has a distribution area of interpretation of the heavy metal element Fe is  783.14 Ha, then for Lawewu River has an interpretation of an area of 1,408.32 Ha and for the Incoiro River, it has an interpretation of an area of 2282.33 Ha. From the results obtained, it can be concluded that the water quality in the three rivers has been polluted by heavy metal Fe
