To be a good aquifer, the rock in the aquifer must have good: porosity: small spaces between grains permeability: connections between pores To reach an aquifer, surface water infiltrates downward into the ground through tiny spaces or pores in the rock. The water travels down through the permeable rock until it reaches a layer that does not have pores; this rock is impermeable (Figure 1.1). This impermeable rock layer forms the base of the aquifer. The upper surface where the groundwater reaches is the water table. Groundwater is found beneath the solid surface. Notice that the water table roughly mirrors the slope of the lands surface. A well penetrates the water table. For a groundwater aquifer to contain the same amount of water, the amount of recharge must equal the amount of discharge. What are the likely sources of recharge? What are the likely sources of discharge? What happens to the water table when there is a lot of rainfall? What happens when there is a drought? Although groundwater levels do not rise and fall as rapidly as at the surface, over time the water table will rise during wet periods and fall during droughts. In wet regions, streams are fed by groundwater; the surface of the stream is the top of the water table (Figure 1.2). In dry regions, water seeps down from the stream into the aquifer. These streams are often dry much of the year. Water leaves a groundwater reservoir in streams or springs. People take water from aquifers, too. Groundwater meets the surface in a stream (Figure 1.2) or a spring (Figure 1.3). A spring may be constant, or may only flow at certain times of year. Towns in many locations depend on water from springs. Springs can be an extremely important source of water in locations where surface water is scarce. A well is created by digging or drilling to reach groundwater. It is important for anyone who intends to dig a well to know how deep beneath the surface the water table is. When the water table is close to the surface, wells are a convenient method for extracting water. When the water table is far below the surface, specialized equipment must The top of the stream is the top of the water table. The stream feeds the aquifer. A spring in Croatia bubbles to the surface and feeds the river Cetina. be used to dig a well. Most wells use motorized pumps to bring water to the surface, but some still require people to use a bucket to draw water up (Figure 1.4). An old-fashioned well that uses a bucket drawn up by hand.

Zach Conroy and Celeste Mercier are the hottest couple on and off the ice until a nasty spill knocks Celeste out of competition. With their dreams of gold medals put in ice and their romance chilling as a result, Zach has to find another partner for the championship in Paris. And fast. In glides Alejandra Alex Delgado, a beautiful, tough talking hockey player with fierce moves and a fearless skating style. Zachs willing to give her a chance, but his coach, Bryan quits in a huff to train Zachs biggest rivals, Cindy Halgyord and Jason Bright. That leaves Zach with a newbie partner and no coach until he convinces former figure skating champ Jackie Dorsey to step in. She puts Zach and Alex through their paces, but the hardest trick of all is keeping them focused on practice and not each other as they bicker and struggle with a growing attraction both on and off the ice. Jackie knows these kids are fire and ice, and sees the chemistry between them. She also knows that if they cant get it together, theyll set the skating world on fire. That is, if the heat between them doesnt cause a total meltdown. With the competition fierce and the stakes higher than ever, the only way Zach and Alex can win is by putting aside their feelings and pulling out a secret weapon: the deadly Pamchecko jump. But is it worth the risk? Can Zach rise above the past and his history of injuring partners? And can Alex prove that shes got the moves to match her passion? It all comes down to the biggest moment of their lives when they learn that sometimes on the ice and in life youve got to risk it all.
Who refuses to coach the pair?
