<![CDATA[The Sukaregang leather tanning industry has grown rapidly since the 1920s. Currently, there are an estimated 300 home-based leather craft industries in this area. This study attempts to examine the spread of chromium from the Sukaregang leather tanning industry in the surrounding soil. The research was conducted using a model. From the results of the chromium dispersion model simulation, zoning of groundwater pollution around the industry will be obtained, which will be useful for the local government in formulating a concept for pollutant control. The input for the modeling is geological data, morphology, hydraulic conductivity, groundwater level data, and chemical data on wastewater and groundwater. To that end, geophysical measurements, drilling and pumping tests, wastewater and groundwater sampling, and chemical analysis were carried out. In the Sukaregang Industrial Area, there are three wastewater treatment plants (IPAL) for around 300 household industries that produce an average of 900 m3/day of wastewater. Of the three IPALs, only one is operational. Chemical analysis of wastewater samples from tanning processes in groundwater revealed the presence of chromium. Modeling results indicate that groundwater flows northward.]]>
