Answer to Question 1

Porosity determines the amount of groundwater that earth materials can hold. Permeability is the
ability of those materials to transmit fluids. If a rock has high porosity but low permeability, it contains
a great deal of water, but that water cannot be extracted.

Answer to Question 2

Precipitation filters into the ground and seeps down through the voids in soil, sediment, and rocks.
Groundwater can also come from water infiltrating from streams, lakes, swamps, artificial recharge
ponds, and water-treatment systems.
