  1. Silver Oaks Comparing the benefits and risks associated with the attempts to clean up Silver Oaks

  2. Benefits to Clean-up • Make town, land safer for the citizens • Assure no more risk of contamination • Cleaner and Safer drinking water • Healthier environment and ecosystem

  3. Risks with Clean up • Transportation- movement of toxic material from one place to another • Possible “dual” site contamination • increased traffic risk

  4. Risks with Clean up • Removal of contaminated soil causes large areas of debris and dangerous construction sites • Soil debris may make air temporarily contaminated • Area homes businesses affected by clean up

  5. 4 Main Ways of Clean up • Excavation- “Dig it all up and take away” • Incineration- “Dig it up and burn baby burn” • Containment- “Trap it and remove it” • Electrification- “Zap it to oblivion”

  6. Excavation • Quickest Method • Removes all the Contamination • Contamination then transported to proper facility • GUARENTEES all pollution is gone • HIGHEST COST • Large destruction of homes/businesses • Soil would have to be replaced making cost extremely high

  7. Incineration • Similar to Excavation • Burns Soil and Contaminated ground water • Eliminates travel concerns of moving pesticide • GUARENTEES Removal of Pesticide • Incinerator donated by chemical company • 3rd most costly plan • Filters in smokestack would eliminate most pollution • Burned soil would then be replaced into ground

  8. Containment • Entrapment of groundwater • Works slowly • Would take up to 15 years to reduce contamination levels • Trapped water then shipped and dumped into ocean • 2nd most costly method • Cost high due to monitoring needs and shipping of water • Limited Digging, less disruption of peoples lives Barrier

  9. Electrification • High energy electric field would be produced to remove chemical • Work 100 in lab setting • Lowest Cost • Unknown health effects of electric field on life forms • Would take 15 years to work • Eliminates most digging • Less homes and businesses affected

  10. Comparing the Methods
