4. Aquifer means a geological formation which has structures or textures that hold water or permit appreciate water movement through them.
6. The ease with which a fluid (air or liquid) can pass through a porous material.
7. not allowing fluids to pass through a material.
8. In a solution, a measure of the amount of dissolved substance contained in a specific volume of liquid. (Ex.) The salt water concentration is 10% (10 grams salt/100 mls. water).
10. A saturated, low permeability earth material can restrict the movement of groundwater and/or it may be able to store groundwater.
11. Compacted layers of clay, silt or rock that act as a barrier for groundwater to flow underground. These earth materials also limit and direct the surface water which seeps down and replenishes aquifers.
12. To make a substances unfit for use by adding something harmful or unpleasant to it. (Ex.) The water is contaminated with chemicals.
13. Water on land that seeps (infiltrates) into the ground. Groundwater also flows downhill through soil and rock.

1. Groundwater can be extracted from underground layers of water-bearing permeable rock, rock fractures or gravel, sand, or silt.
2. A substance used for destroying insects or other organisms harmful to cultivated plants or to animals.
3. A body of contaminated groundwater or stream flowing from a specific source.
5. A geological formation with holes, or small pore spaces within porous materials such as rocks, soil etc. that can hold water or permit water movement.
9. The saturated zone of the aquifer (under ground water table) that interfaces with earth's surface. This saturated zone is seasonal.
