Saltwater intrusion can occur in aquifers near coastlines, when fresh groundwater in the aquifer is displaced by salt water. Coastline aquifers become more vulnerable to saltwater intrusion when freshwater recharge rates are low or withdrawal rates are high. An aquifer in which of the following areas would be most affected by saltwater intrusion?

• a small coastal town experiencing a rainy summer

• a coastal agricultural area using periodic irrigation

• a large inland region of growing cities and farms

• a growing coastal city undergoing a drought

A regional water board is examining proposals to provide drinking water to a growing metropolitan area. Which of these proposals is most likely to deplete groundwater supplies?

• installation of city-owned wells within each neighborhood

• construction of a dam to create a large water reservoir

• placement of stations along a river to capture and filter water

• establishment of a water treatment plant next to a large lake

Subsidence is the collapsing or sinking of land. Subsidence can happen for many reasons. Often it happens when an underground material, such as rock, dissolves and leaves empty space behind. The empty space cannot support the material at the surface. The land above it sinks or collapses. Assuming that the voids underground are forming at the same rate, which of the following would most likely have areas that undergo subsidence?

• a pine forest

• a field of corn

• a large city

• a small town

Look at the diagram of a stream with toxic chemicals flowing into it. This diagram models how toxic runoff can pollute a stream and also –

• produce acid rain.

• cause soil erosion.

• create algae blooms.

• pollute groundwater.

• sand

• grass

The empty spaces in a material are called pores. Porosity is the amount of empty space within a material. Permeability describes how well the pores in a material are connected. Which of these materials would make the most effective aquifer?

• a material that has high porosity and high permeability

• a material that has high porosity and low permeability

• a material that has low porosity and high permeability

• a material that has low porosity and low permeability

Which of the following is most responsible for reducing the availability of fresh water in this country?

• aquifer depletion

• reservoir evaporation

• nonpoint source pollution

• boat and watercraft emissions
