Waste Characterization

Sidebar Image

Eurofins Lancaster Laboratories Environmental routinely performs Waste Characterization testing on solid and liquid samples to determine if material is considered hazardous based on the RCRA definition in 40 CFR Subpart 261. The data we produce assists our clients in determining proper waste management and disposal practices.

We can test solids, liquids and other waste materials. For samples with greater than 0.5% solids a leachate extract is created in our custom built, EPA-approved Agitation Apparatus, which rotates the extraction vessels at 30 ±2 rpm in an end-over-end manner. Samples with less than 0.5% solids are filtered through 0.6 – 0.8 micron glass fiber filters. The samples are subsequently analyzed for the tests listed below.

The tests methods utilized to determine if a sample exceeds a hazardous waste criteria include:

  • Toxicity Characterization Leaching Procedure (TCLP) by Method SW-846 1311 is used to determine the mobility of organic and inorganic contaminants in potentially hazardous waste.

    One or all of the following analyses are performed on the leachate/filtrate sample:

    • Volatiles by SW-846 8260B
    • Semivolatiles by SW-846 8270C/D
    • Pesticides by SW-846 8081A/B
    • Herbicides by SW-846 8151A
    • Metals by SW-846 6010B/7470A
  • Synthetic Precipitation Leaching Procedure (SPLP) by Method SW-846 1312 is used to determine the pollutant mobility of organic and inorganic contaminants under conditions that simulate rainwater percolating through a sample.

    One or all of the following analyses are performed on the leachate/filtrate sample:

    • Volatiles by SW-846 8260B
    • Semivolatiles by SW-846 8270C/D
    • Pesticides by SW-846 8081A/B
    • Herbicides by SW-846 8151A
    • Metals by SW-846 6010B/7470A
  • Corrosivity - SW-846 Chapter 7
  • Ignitability (Solids) - 40 CFR 261.21
  • Flashpoint (Liquids) - ASTM D 93-07 or SW-846 1010A
  • Cyanide and Sulfide Reactivity - SW-846 Chapter 7/9012A Mod/9034

Also available for our clients located in California is the Soluble Threshold Limit Concentration (STLC) Waste Extraction Test (WET) based on CCR Title 22 WET Section 66700.
