 ==Final Site Renovation/Remediation==
 *Finally any temporary gear would be moved out and either a new liner be placed and “rinse and repeat”, or all remnants of Landfill Infrastructure would be removed and the sight either [[Rewilded]] (akin to [[Mine Reclamation]] ) or Leveled and developed for higher level uses (Such as Farmland, Housing, [[Mixed Use Development]] etc)

 *Alternatively adding in more pipes for air/suction, or even removing the top “Cap” section of the liner/clay to allow for faster drying may be beneficial

			===Leachate Removal and Drying===
			*In modern landfills ( [[Bioreactor Landfill]] ) leachate is recirculated from the bottom of the landfill to the top to aid the biodegradation
			*Before final excavation (regardless of prior pre-treatment processes/in-situ recovery methods) this will need to be minimized if not removed altogether
			**Methods to reduce leachate remaining / the benefits of concentrating it vs additional costs flr disposal of said concentrated leachate etc are worth analyzing
			*Removal of Piping/[[Monitor Wells]] may aid in later excavation/drilling as well
			*Alternatively adding in more pipes for air/suction, or even removing the top “Cap” section of the liner/clay to allow for faster drying may be beneficial
