Human Impact on Watersheds

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.
