First Environmental Laboratories is able to analyze your waste sample for specific characteristics to determine if it is a hazardous waste as regulated under the Resource Conservation and Recovery Act (RCRA).  The characteristic properties that define a hazardous waste include: ignitability, corrosivity, reactivity, and toxicity.

 

To determine toxicity the EPA developed a lab procedure called Toxicity Characteristic Leaching Procedure (TCLP) to replicate the leaching process that occurs when a waste is buried in a landfill.  The leachate that is created in the lab using this procedure is analyzed to determine if it exceeds regulatory limits for 39 different compounds.

        *If o-, m-, and p-cresols cannot be individually measured, the regulatory level for total cresols is used.

 

Prior to performing any lab testing for hazardous waste characteristics we suggest that you contact the landfill where your waste is destined.  Many landfills have their own acceptance criteria which depend on the type of waste you are disposing.
