Natural Resource
Damage Assessments
Contaminants biologists in Region 3 restore habitats and resources injured by releases of hazardous substances using a process called Natural Resource Damage Assessment (NRDA). The goals of NRDA are to restore the habitats and resources to the condition they would have been had the hazardous substances not been released, and to compensate the public for the loss of their use or enjoyment of natural resources.
