Industrial waste disposal

Agricultural runoff

Urban development

Natural filtration

Drilling wells too deep

Removing too much water from aquifers

Pollutants leaking into the ground

All of the above

To dispose of oil from farms, people drill wells down below the water table.

Pollutants in landfills can leak directly into the groundwater.

Chemicals used on lawns get into groundwater when runoff picks them up and soaks into the ground.

Pumping water into the ground to remove oil and gas causes the water table to drop.

Toxic waste is safe if buried below the level of the basements of nearby homes.

Chemicals applied by farmers lower the level of pollution in drinking water.

Human activities do not affect groundwater.

Drinking water can become polluted from unsuspected sources.

Limit water use and reduce pollutants

Pass legislation to manage groundwater

Monitor and repair fuel tanks

All of the above

Conserve water by limiting how long I wash my bike

Do not follow laws that help manage water use

Dispose of chemicals into the ground

Use more water for washing my bike

The activities prevent most of the water from evaporating into the atmosphere

Pollutants from the activities percolate through the soil and enter the water table.

The activities replace the groundwater used.

All of the above
