1. Garbage: The plague of modern times

2. The Landfill Urgent International and Domestic Problem Common method of waste disposal Unsustainable All landfills will eventually leak into the environment

3. Products Of Landfills Impacts on ecosystems Landfills Water contamination

4. Products of Landfills Methane Gas released from decaying matter VOCs (volatile organic compounds) Breakdown of Organic and Inorganic Waste Produces Leachate: liquid with dissolved harmful substances

5. Water Contamination Less oxygen in water due to garbage Growth of Algae - photosynthesis is hindered Toxic detergents do not decompose

6. Impacts on Wildlife Death of fish due to suffocation Animals can ingest garbage Disease spreading Pollutants such as fertilizers disrupt ecosystems

7. A Three-Pronged Solution Human Activities: Reduce, Re-use, Recycle Biological: Natural Attenuation, Use of Micro-organisms Chemical: Activated Carbon Filtering

8. Expected Costs Cost of Activated Carbon varies depending on size of landfill and gas emitted: ~ $280,000 for a landfill that emits 100 lb/h of gas Natural Attenuation: ~ $326,000 for 2.1 hectares of land: 39 million dollars for Barrie landfill (121.1 ha)
