Form U Analytical Parameters

Parameters for all facilities:

  • pH
  • Ignitability
  • Reactive Sulfide
  • Reactive Cyanide
  • Toxicity Characteristic Leaching Procedure (TCLP), including all parameters found in 40 CFR 261.24


Additional parameters for Class I residual waste and municipal waste disposal facilities:

  • Additional TCLP parameters
    • Copper
    • Nickel
    • Zinc
  • Free Liquids
  • PCBs
  • Water Leaching Procedure (ASTM) 
    • COD
    • Total Solids
    • Oil and Grease or Petroleum Hydrocarbons
    •  Ammonia-Nitrogen
  • Total Solids
  • Total Volatile Solids
  • Total Oil and Grease or Petroleum Hydrocarbons
  • For contaminated soil, TCLP results for other contaminants found in the soil

Additional parameters for Class II and Class III residual waste disposal facilities:

  • Additional TCLP parameters
    • Iron
    • Manganese
  • Phenolics
  • Additional Water Leaching Procedure parameters
    • Chloride
    • Cyanide
    • Fluoride
    • Nitrate
    • Nitrite
    • Sulfate
    • Total Organic Halide 


Other additional parameters may be necessary due to the nature of the waste, waste processing, conditions at the facility, or conditions of the permit.

If the waste is known or suspected to have radioactivity above background levels then an EPA Gamma Specific Activity Analysis for Technically Enhanced Normally Occurring Radioactive Material (TENORM) isotopes including U-238, RA-226, RA-228, TH-232, and K-40 must be conducted
