Land treatment unit
LTUs are becoming more common as more sites needing clean-up are identified.
Land treatment units are areas where hazardous waste is applied or incorporated into the soil surface. Land treatment units are typically units consisting of natural soils where natural biological and chemical degradation and attenuation processes immobilize, transform, or degrade hazardous constituents over time.
