Procedures:
1. Read the articles: Groundwater Use and Overuse and Hudson River in the lesson.
2. Answer the reflection questions for each article. Within the Groundwater Use and Overuse article, use the simulation to answer reflection questions.
3. Some reflection questions ask you to research using internet resources. Be sure to cite the source of your research.
4. Use your own words when responding to the reflection questions.
The biggest reservoir of fresh, liquid water on earth is groundwater. There is more than 20 times as much water stored within the ground as in all the lakes and rivers combined. In many parts of the world, agricultural, industrial, and domestic water demands can only be met by pumping water out of the ground.

As you'll see in the simulation below, wells work only if they penetrate the water table - the name given to the subsurface boundary that separates saturated and unsaturated ground. Above the water table, cracks and spaces between soil and rock particles contain at least some air. Infiltrating water moves more or less vertically as it passes through this unsaturated zone. Below the water table, all openings in the ground are filled with water. Once groundwater reaches this saturated zone, it begins to travel both horizontally and downward, and can flow into wells, rivers, and eventually the sea.

The water table is an irregular surface that generally resembles a gentler version of the overlying ground surface. It is not fixed, but moveable, rising when rainfall adds more water to the ground, and falling when drought reduces the water supply. The depth and shape of the water table can also change dramatically when groundwater is pumped out of the ground. Pumping can quickl
Reflection Questions- Article 1
1. Using the simulation, describe what happens to groundwater when pumping is lower or equal to the rate of infiltration.

2. Using the simulation, describe what happens to the stream and water table as the number of pumps running is increased.

3. How can water needs be met if the rate of infiltration is lower than the rate of pumping?

4. In the simulation, what happened to the stream as the water table dropped? What will happen to the groundwater if a pollutant is added to the stream?

5. Predict long-term changes to the surface landscape of the area if too much water is drawn from the ground and the water table drops further.
