Pesticide leaching

Pesticide leaching is the process by which pesticides, used to control pests in agriculture or gardening, dissolve in water and move through the soil. When it rains or when the soil is watered, these chemicals can be carried down through the layers of soil and potentially reach underground water sources, such as aquifers. This can lead to contamination of groundwater, which is used for drinking and irrigation. Understanding and managing pesticide leaching is important for protecting the environment and ensuring safe water supplies.
