The statement that it is more common in sandy soils than in coarse soils is not accurate. Instead, leaching is typically more pronounced in sandy soils because of their larger particle size, which allows for faster percolation and less retention of water and chemicals. Sandy soils have larger pore spaces, leading to quick drainage and greater potential for pesticides to move downward and leach into ground water.

Leaching does indeed pose a risk of contaminating ground water, which is a significant concern in pest control practices. This is due to the ability of certain pesticides to move with water as it percolates through the soil, potentially reaching aquifers or other water sources.

The process of leaching involves the downward movement of water through the soil profile, transporting dissolved substances along with it. This is a key characteristic of how leaching occurs, contributing to the movement of pesticides from the surface to lower strata.

In heavily treated areas, the likelihood of leaching increases due to the higher concentration of pesticides present, which can lead to enhanced movement through the soil, especially when rainfall or irrigation events occur that mobilize water to facilitate leaching.
