Using Environmental Simulations

1. NIMBY Landfill Siting Kildare Environmental Health Using Environmental Simulations Linda Sigismondi, Ph.D.

2. Yoretown • Landfill nearly full • Needs new site • 4 possibilities • Evaluate • Recommend

3. Yoretown

4. Landfill Siting Criteria • Slope and terrain • Soil Depth • Soil Permeability • Bedrock • Aquifer • Explosive Gas Migration • Wells & Mines • Access • Zoning • Location • Residences • Natural Features • Nature Preserve • Airports

5. Site Information

6. Landfill Site Comparisons

7. Other Possibilities • Transport trash to another area • Incineration • Recycling/Compost

8. Additions to Activity • Build a landfill model • Compare soil permeability • Examine bedrock samples

9. An Environmental Health Simulation KILDARE, USA

10. MAP OF KILDARE, USA N=10,000 1000 600 Lake Rainbow 500

11. 15 individuals diagnosed with illness Rash, arthritis progressing to seizures/paralysis Your group is a team of environmental sanitarians assigned to investigate the illness and control its spread. Money is available but use wisely since the more you spend the less is available for other town issues. SCENARIO

12. INITIAL OPTIONS

14. CONCLUSION PART 1? • all have lake and fish in common • no common toxins or pathogens in lake, (air, soil) • All are homozygous for gene for I-roll

15. OPTIONS PART 2

16. CONCLUSION PART 2? • Chemical called I-Swing in Lake (legal levels) • Discharged by EPC • High concentration in game fish • Those affected have high concentrations of U-shake in blood

17. OPTIONS PART 3

18. CONCLUSION PART 3 • I-swing bioaccumulates • Biomagnification of I-swing in food chain • Those with I-roll convert I-swing to U-shake • U-shake accumulates, causes symptoms

19. CONCLUSION PART 3 • I-swing bioaccumulates • Biomagnification of I-swing in food chain • Those with I-roll convert I-swing to U-shake • U-shake accumulates, causes symptoms
