If the soil in an area is mostly clay, would it be a good place to dig a well?

• Yes, because clay allows water to flow quickly underground

• No, because clay does not allow water to pass through easily

• Yes, because clay holds a lot of water

• No, because clay is too soft to dig through

What is the most likely reason for groundwater to be unavailable in a specific location?

• The area has too much precipitation

• The water table is too low or the ground is not porous enough.

• The soil is too sandy

• There are too many trees

Why is groundwater important for communities that may not have access to a lake for water?

• Groundwater provides a reliable and accessible source of drinking water for communities without lakes.
• Groundwater is not safe for drinking without treatment.
• Groundwater is less reliable than rainwater.
• Groundwater is only useful for irrigation purposes.
