Geochemical Remediation
nounPronunciation: /ˌdʒiːoʊˈkɛmɪkəl ˌrɛməˈdeɪʃən/
The application of geochemical principles to treat contaminated mine sites by manipulating soil and water chemistry through amendments, oxidation-reduction reactions, or pH adjustment. This approach reduces metal mobility and pollutant bioavailability in soil and groundwater.
Plain English
Treating mine contamination by changing soil and water chemistry to reduce harmful metal movement.
Etymology & History
Usage
"Geochemical remediation using limestone amendment successfully reduced arsenic leaching at the former gold mining site."
Style guide notes: Specify amendment type and mechanism of action; include baseline and post-treatment chemistry data.
