Ex situ
Glossary of common terms used in the management of land contamination, published on the Planning Portal, defines ex situ as: ‘Where contaminated material is removed from the ground prior to above-ground treatment or encapsulation and/or disposal on or off-site.’
This is as opposed to in situ: 'Where contaminated material is treated without prior excavation (of solids) or abstraction (of liquids) from the ground.'
