Geochemical Stabilization
nounPronunciation: /ˌdʒiːoʊˈkɛmɪkəl ˌsteɪbəlɪˈzeɪʃən/
The application of chemical amendments or additives to immobilize contaminants in soil and rock materials by altering their chemical speciation and reducing bioavailability. This technique prevents contaminant migration and reduces environmental exposure pathways.
Plain English
Using chemical treatments to lock contaminants in place so they cannot move or be absorbed by plants and animals.
Etymology & History
Usage
"Geochemical stabilization using ferrous sulfate successfully reduced arsenic mobility in the reclaimed mine site."
