×IDENTIFICATION CONTAMINATION GROUNDWATER WITH
GEOELECTRICAL AT NGRINGO JATEN KARANGANYAR

Geoelectrical resistivity surveys have been conducted using Schlumberger
sounding configuration of 4 points at Ngringo Jaten Subdistrict Karanganyar
District. Measurements were carried out using OYO model 2119C
Resistivitimeters. Data was processed using IPI2Win Ver. 2.6.3a, with the results
of processing in the form of depth, thickness and number of layers and the
resistivity value. Results of data processing was determined based on the
recommendation percentage error model with the smallest to the mapping
information isoconductivity, geology, and the information well. The distribution
of research results of groundwater pollution in the Village Ngringo is not evenly
distributed. Contamination was identified in the depth of 13.6 - 23.6 meters with a
flow direction from North to South with the regional distribution in the southern
and at depth of 7.5 - 60 meters with a flow direction from west to east with the
regional distribution in the east. Groundwater pollution does not occur in the
distribution area to the northern aquifer identified with the depth of 157 meters.
Distribution of overall groundwater pollution Ngringo Village Jaten Subdistrict is
uneven, contamination happens as a consequence of contamination seepage from
river at area with neighbourhood of less than 1 km from river.
Keywords: resistivity, isoconductivity, groundwater pollution, distribution
