Barrier Encapsulation
nounPronunciation: /ˈbæriər ɪnˌkæpsjʊˈleɪʃən/
The process of covering or sealing contaminated materials with engineered barriers such as clay liners, synthetic membranes, or capping layers to prevent migration of contaminants into surrounding soil and groundwater. This approach isolates hazardous mine residues without requiring full removal or treatment.
Plain English
Covering contaminated mine materials with protective sealing layers to stop pollution spread.
Etymology & History
Usage
"The remediation plan selected barrier encapsulation with a three-meter clay cap to contain the oxidized pyrite waste rock."
Style guide notes: Use 'barrier encapsulation' as a unified term; specify barrier type when describing specific implementations.
