Post-Closure Monitoring
The required surveillance of closed mines, landfills and industrial sites — water quality, stability, emissions — to confirm they remain safe after operations end.
Definition
Post-closure monitoring is the systematic measurement and inspection carried out after a facility — mine, landfill, waste repository or industrial site — stops operating, to verify that containment systems perform, pollution remains within limits and physical stability is maintained. Regulatory regimes typically mandate defined monitoring periods (for landfills often 30 years or more) with financial provision secured in advance.
