For each statement,write true or false. __ 11. To produce water a well must be drilled deep into aquicludes. __ 12. It is very difficult to cause drawdown in an aquifer no matter how many wells are tapped into the aquifer. __ 13. An important artesian aquifer in the United States is the Ogallala Aquifer.

## Step1<br />The first statement is about the depth at which a well must be drilled to produce water. Aquicludes are geological formations that are impermeable to water. If a well is drilled into an aquiclude, it would not be able to produce water because the water cannot move through the material. Therefore, to produce water, a well must be drilled into an aquifer, not an aquiclude.<br /><br />## Step2<br />The second statement is about the difficulty of causing drawdown in an aquifer. Drawdown refers to the lowering of the water table around a well due to pumping. The difficulty of causing drawdown depends on several factors, including the rate of pumping and the permeability of the aquifer. It is not inherently difficult to cause drawdown in an aquifer, especially if multiple wells are tapping into it.<br /><br />## Step3<br />The third statement is about the Ogallala Aquifer. The Ogallala Aquifer is indeed an important artesian aquifer in the United States. It spans several states in the central United States and is a critical source of water for irrigation and other uses. The term "artesian" refers to an aquifer in which water rises above the top of the aquifer under natural pressure. The Ogallala Aquifer is considered an artesian aquifer because it has areas where the water table is above the land surface.
