What remediation planning approach must be taken for sites contaminated by persistent heavy metals from historic industrial waste?
Answer
Planning for management strategies like capping or physical removal rather than waiting for natural attenuation
Sites contaminated by historic industrial waste, particularly with heavy metals, can remain hazardous indefinitely, requiring management strategies like capping or physical removal rather than relying on natural attenuation.
