Traditional ParadigmTraditional Paradigm
F Wastes contaminated with semi-volatile organicshave traditionally treated via thermal treatmenttechnologies
F Public and regulatory acceptance of thermaltreatment has declined
F Alternative remedial technologies (bioremediation,soil vapor extraction, chemical oxidation, and soilwashing) do not have the same level of destructionas thermal treatment technologies

Stabilization of Organics as aRemedial AlternativeStabilization of Organics as aRemedial Alternative
F The traditional alternative remedialtechnologies leave residual levels of organicsafter treatment
F The residual levels may be unacceptable orrequire containment of the treated material
F Stabilization, or chemical fixation, can beacceptable since the organics are immobilizedin the treated material, limiting their impact tohuman health and the environment

Corrective Measure at SFAAPCorrective Measure at SFAAP
F Building Foundation Area, Ditchand Settling Pond soils werecontaminated with lead,nitroglycerine, and nitrocellulose– Could be reactive if
concentrations of propellantare high
F Kansas DPH and Region VIIagreed to a stabilized materialwhich was not RCRAcharacteristically hazardous forreactivity and leached less than0.75 mg/L lead
