Many businesses confuse WAC testing with standard waste classification, but they serve different purposes. Understanding the distinction is essential for proper waste management.

Waste Classification
  • Determines whether waste is hazardous or non-hazardous based on its chemical composition.
  • Required before any waste is removed from a site.
  • Uses chemical analysis to assess toxic, corrosive, or reactive properties.
WAC Testing
  • Assesses how waste will behave once deposited in a landfill.
  • Determines the leachability of hazardous substances.
  • Required only if waste is being sent to landfill.
Why Both Are Important
  • A material may be hazardous but meet landfill WAC criteria, allowing disposal at specific landfill sites.
  • Conversely, non-hazardous waste may fail WAC testing due to excessive leachability and require pre-treatment.
