WAC Testing vs. Waste Classification: What’s the Difference?

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.
