Answer:
c. leachate collection and removal system
Step-by-step explanation:
A leachate collection and removal system is a barrier method of pollution prevention because it physically prevents the leaching of hazardous substances from a landfill into the surrounding environment.
The other options are not barrier methods of pollution prevention.
- Double clay liners are used to prevent the migration of hazardous substances from a landfill into the surrounding environment. However, they are not a physical barrier, so they are not considered a barrier method of pollution prevention.
- Groundwater monitors are used to detect the presence of hazardous substances in the groundwater. They do not prevent the leaching of hazardous substances from a landfill, so they are not considered a barrier method of pollution prevention.
- Monitoring wells are used to collect groundwater samples for analysis. They do not prevent the leaching of hazardous substances from a landfill, so they are not considered a barrier method of pollution prevention.
