we use soil data to answer a very wide range of questions - from the obvious ones such as "which crops grow best where?" to more specific ones, such as "if we put this type of pesticide on this field, where will it end up? The river, the aquifer, or will it degrade in the soil?"

A highway could remove enogh soil that it could expose the aquifer to air and the chemicals, such as tar might contaminate the aquifer as well.

aquifer
An aquifer is not a type of water. It is an underground layer of permeable rock, sediment or soil that contains water. Wells are dug to reach this layer to obtain water.
Because it is stopped by a boundary which is not porous.
Water can eventually reach a layer of impermeable rock which does not allow its further downward passing. This is the base layer which creates the aquifer.
