Interpret: If the current rate of groundwater extraction continues, what might be a long-term effect on the aquifer?

• The aquifer will recharge faster.

• The aquifer will become more sustainable.

• The aquifer will maintain its current level.

• The aquifer will eventually dry up.

How can human activities such as agriculture affect groundwater quality in a watershed?

• They have no effect on groundwater quality.

• They can introduce pollutants like pesticides and fertilizers into the groundwater.

• They improve groundwater quality by adding nutrients.

• They only affect surface water, not groundwater.
