Among these substances, heavy metals are considered to be the most dangerous due to their high level of toxicity and non-degradable nature. It is indicated that Citarum River, which is located in Dayeuh Kolot, Bandung District, West Java Province, is polluted with metal-containing waste. The purpose of this research is to identify metal substances in the ground water so that the usage of these waters can be prevented. Metal substances have high magnetic susceptibility, therefore geomagnetic method is used to identify these substances in the river. Survey is done in 3 lines with a spacing of 25 meters. Sample is taken in the research area by using a modified PVC pipe and analyzed through laboratory analysis. Susceptibility data taken by geomagnetic method is correlated with magnetically-analyzed core samples. Results show that high level of noise in the area affecting the geomagnetic method acquisition resulted in a difference in trend between the magnetic anomaly and the χLF values from laboratory analysis. Further measurements and analysis alongside the χLF values is needed to estimate the metallic content of polluted water.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]coring,geomagnetic,metal,susceptibility,Waste[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This study was funded by Geophysical Engineering of Bandung Institute Technology.
