Similar to dry cleaner soils, pesticide contaminated soils are classified as listed hazardous when a listed hazardous pesticide compound such as Chlordane, Heptachlor, Lindane, Methoxychlor or Toxaphene is detected in any concentration, via Totals (dry weight) analysis.

Pesticide contaminated soils are classified as characteristically hazardous when a pesticide is detected at concentrations greater than or equal to its respective RCRA limit, via TCLP analysis.

Pesticide contaminated soils can also carry a combination RCRA waste code, such as U036/D039 when classified as both listed hazardous as well as characteristically hazardous.

Such soils are classified as non-hazardous when there is no KNOWN source of a pesticide release or spill (excluding pesticide detections resulting from normal spraying applications), and also no TCLP PCE detections greater than or equal to 0.7 mg/L.
