Question

what risk is associated with the rapid movement of substances in highly permeable soil? enhanced soil fertility better crop growth reduced use of fertilizers contamination of groundwater

Explanation:

In highly permeable soil, substances can move quickly. This can lead to contaminants in the soil - like fertilizers, pesticides, or industrial chemicals - seeping into the groundwater, which is a risk. The other options are benefits rather than risks. Enhanced soil fertility, better crop growth, and reduced use of fertilizers are positive aspects and not risks associated with the rapid movement of substances in highly permeable soil.

Answer:

contamination of groundwater
