What is Ground Water?

Where does most city water come from?

• Surface water resources

• Underground aquifers

• Rainwater collection

• Desalination plants

What does it mean for a material to be porous?

• It allows liquids to pass through it

• It holds a lot of water

• It has small spaces or holes in it

• It flows easily through gravel and sand

What is an aquifer?

• A type of fish found in underground rivers

• A saturated area of sediment or rock that groundwater can move through

• A device used to measure water pressure

• A type of well used for irrigation

What is the water table?

• The top layer of soil that holds water

• The layer of clay that prevents water from flowing

• The very top of the saturated zone where all the open spaces are filled with water

• The zone above the capillary fringe where the soil begins to desaturate

What is the purpose of a well?

• To store groundwater for future use

• To prevent flooding in low-lying areas

• To provide a source of clean drinking water

• To create a dam and trap water for wetlands

What is the difference between a confined aquifer and an unconfined aquifer?

• A confined aquifer is connected to the surface, while an unconfined aquifer is not

• A confined aquifer can hold more water than an unconfined aquifer

• A confined aquifer has impermeable layers that prevent water flow, while an unconfined aquifer does not

• A confined aquifer is located deeper underground than an unconfined aquifer

What is the purpose of wetlands in relation to groundwater?

• To recharge the groundwater table

• To provide a source of clean drinking water

• To prevent flooding in low-lying areas

• To trap water and create a dam

How do rivers and streams interact with groundwater?

• Rivers and streams always gain flow from groundwater

• Rivers and streams always lose flow to groundwater

• Some rivers and streams gain flow from groundwater, while others lose flow to groundwater

• Rivers and streams have no interaction with groundwater

What is the purpose of managing groundwater sustainably?

• To ensure future generations have access to safe, clean water

• To prevent contamination of surface water resources

• To increase the water table levels

• To reduce the reliance on city water sources

Who is responsible for managing groundwater sustainably?

• The government

• Individual well owners

• Water treatment plants

• Environmental organizations
