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)
