In its original place (cleaning soil exactly where it sits).

Said the earthworms would help with soil binding. The reclamation strategy involves covering the site with

The passage states the opposite. Researchers selected specific, hardy strains of earthworms that were highly tolerant of industrial waste. Despite the presence of heavy metals, these specialized worms managed to survive, thrive, and reproduce.

Parallel to the worm activity, Scottish Greenbelt planted , such as willow and alder, which help extract contaminants through their roots—a process known as phytoremediation.

Earthworms require a baseline food source to survive initially. Successful projects often apply a top layer of organic waste, such as treated sewage sludge (biosolids), compost, or agricultural waste. →right arrow FALSE 2
