Cleanup Objectives: Clean up illegal dump encompassing 5,000 cubic yards of debris

Greener Remediation Strategy:

Constructed a four-foot-thick monolithic evapotranspiration cover in semiarid climate

  • Salvaged wood scraps and concrete for erosion control
  • Chipped or shredded wood to create mulch for recreational trails
  • Recycled 31.6 tons of metal
  • Salvaged concrete for later use as fill for building infrastructure
  • Powered equipment through use of biofuel generators and photovoltaic panels, due to lack of electricity
  • Extracted 680 tires through use of vegetable-oil powered tractor
  • Inoculated chainsaws with fungi spore-laden oil to aid in degradation of residual contaminants
  • Constructed floating islands(of recovered soda bottles) to create habitat for life forms capable of bioremediating residual toxins in onsite retention pond
  • Planted native grasses, wildflowers, and trees

Results:

  • Re-established wildlife habitat for native and endangered species
  • Gained community help to restore the property within a single year

Property End Use: Environmental education park
