Based on observations, the water which passes through the neighborhood is dark brown with bad odor. However, the water from Cikijing river is still used to irrigate the nearby rice fields and for public consumption. The contaminated water allegedly seeps into the ground and pollutes the shallow aquifer underneath. First, the magnetic susceptibility measurement is applied to the sample taken from the riverbanks as an indicator to confirm the heavy metal contamination suspected to be contained by the shallow aquifer. The soil samples collected from the river shows the high value of magnetic susceptibility which reflects contamination by heavy metals. Heavy metals contained by the contaminated aquifer will induce the water to be more conductive thus making the resistivity value lower than the uncontaminated water. With electrical resistivity method, the distribution of the contaminated shallow aquifer can be detected. The resistivity measurement is performed in the rice field nearby using Wenner-Schlumberger configuration. The resistivity contrast indicates the association of the aquifer with the contamination. Through the resistivity and magnetic susceptibility methods, the contamination of the shallow aquifer can be confirmed and its distribution can be revealed.[/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]Aquifer,Contaminant,Magnetic Susceptibility,Resistivity[/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][/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1063/1.5047303[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
