摘要：Hazardous waste is a waste with properties which can pollute and damage the environment, human health, and
other living things. Lakardowo is a village that is suspected of being contamination by hazardous waste derived from
industrial activities. Measurements with the VLF-EM and Resistivity method were used in this study. In addition,
groundwater level mapping and soil sampling in locations around the industry were conducted for the XRF test.
Groundwater mapping results show that groundwater flow leads to the Northeast-South and Southwest of the industrial
site. The soil samples that have been tested by XRF show the presence of heavy metals, wherein hazardous wastes generally
contain various types of heavy metals that are conductive or have low resistivity values. Quantitative interpretation of VLFEM
data shows the presence of low resistivity anomalies at several measurement sites, which are suspected of having been
contaminated with soil by waste. Resistivity data processing results, showing a low resistivity anomaly (≤ 3 Ω.m) located to
the north (near an industrial site) and spreading towards the southwest along the measurement path. The result of a
combination of quantitative interpretations of both methods, obtained, the direction of anomalous flow of hazardous waste
moves southeastward and towards deeper soil coating following the direction of rock coating.
