• Solid waste is most often disposed of in landfills. Landfills can contaminate groundwater and release harmful gases.
• Electronic waste, or e-waste, is composed of discarded electronic devices including televisions, cell phones, and computers.
• A sanitary municipal landfill consists of a bottom liner (plastic or clay), a storm water collection system, a leachate collection system, a cap, and a methane collection system.
• Enduring understanding STB-3: Human activities, including the use of resources, have physical, chemical, and biological consequences for ecosystems.
