Study of Industrial Liquid Waste Pollution Using Geoelectrical Method in Sukaregang, Garut, West Java

Abstract

The rapid development of industry causes more and more waste to be produced and can lead to pollution. One of those is the pollution of the leather tanning industry in Sukaregang, Garut, West Java. Tannery waste is disposed of directly into the river area. Seepage of waste below the surface from river flows results in groundwater contamination which affects the availability of clean water. In this study, measurement of the geoelectric method was carried out to determine the distribution pattern of subsurface groundwater pollution based on variations in the resistivity value. Data retrieval was carried out on three parallel lines using the Wenner configuration. The distance between the measurement line is 5 m with the distance between the electrodes as long as 4 m. Results showed that resistivity values varied from 0.1 to 181.9 m. These values are associated with clay rocks with different densities. On the three lines, there is a low resistivity anomaly of less than 8.61 m which is thought to be part of the contaminated seepage of liquid waste. Allegedly polluted areas on the three tracks are at the measurement point of ±10 to ±20 m with a depth of about 0-8 m.
