Soil heterogeneity affects how contaminants move through the ground. Scientists in South Korea used geostatistical methods to map soil properties like density, water content, and conductivity. They took samples every 20 meters in a 0.6 km² area and tested them in a lab. By creating 3D maps and comparing the properties, they found patterns in how the soil characteristics are connected. This helps us understand how contaminants might spread in the environment.
