13. Current waste disposal methods
dump it (landfill)
bury it (landfill)
burn it (incinerator)

14. Dumped or buried trash
Municipal landfills regulated locally or by state. Federal regulations prevent them from being near wetlands and earthquake prone faults and be 20 ft. above the water table.

15. Chemicals are released into the air.
Incinerated trash
Toxins still remain.
Chemicals are released into the air.
Some nations have banned incinerators.

16. Runoff and groundwater?
Leachate: Liquid that results when substances from the trash dissolve into water as rainwater percolates downward.
Landfill managers are required to maintain leachate collection systems for 30 years after landfill has closed.
Regulations also require that groundwater be monitored regularly for contaminations.

17. Sanitary landfills are an improvement over open dumping.
Comparison
