Phase Separation Science analyzes soil samples that are regulated under a number of programs including the:

  • Brownfields sites for cleanup and redevelopment
  • Hazardous waste characterization for disposal and other wastes regulated under Resource Conservation Recovery Act (RCRA)
  • Leaking Underground and Above Ground Storage Tanks (UST/AST)
  • Site investigations or confirmation sampling

Soil samples are analyzed for contaminants by EPA SW846 Methods (Test Methods for Evaluating Solid Waste, Physical/Chemical Methods) to determine if they meet state or federal cleanup standards under the Resource Conservation and Recovery Act (RCRA). In addition to regulated cleanup levels, disposal facilities that take in contaminated soils have their own requirements.

TCLP is the appropriate leaching method when examining the leaching potential of a soil, water or waste in a landfill. The action levels are set regulatory limits for hazardous waste and can be found on line in 40 CFR 261.21-24. However, when determining the impact to groundwater or surface waters from material left in situ, it is more appropriate to use the SPLP (Synthetic Precipitation Leaching Procedure).
