What is the potential outcome of a more soluble pesticide regarding its movement to groundwater?

A more soluble pesticide has a greater potential for movement to groundwater because its chemical properties allow it to dissolve easily in water. When a pesticide is highly soluble, it can be carried along with water as it infiltrates the soil during rain events or irrigation. This transport process increases the likelihood of the pesticide leaching through the soil layers and reaching the groundwater aquifers below.

In contrast, a less soluble pesticide tends to remain bound to soil particles and may not move as readily with water, reducing the chances of it contaminating groundwater supplies. The solubility rating of a pesticide is crucial in assessing environmental risks, especially concerning water sources, which are vital for human consumption and ecological health.
