Environmental Contaminants Specialists are available to:


  • Investigate fish and wildlife die-offs
  • Investigate pollution effects on fish, wildlife, and habitat
  • Identify sources of pollution
  • Respond to oil and hazardous material spills or releases
  • Restore habitats and resources degraded by pollution
  • Provide advice to minimize the use of pesticides and fertilizer
  • Provide technical expertise to other federal agencies, states, industrial, and agricultural interests


To request help or for more information, please call the East Lansing Field Office at 517-351-2555.



East Lansing Field Office Contaminants biologists investigate effects of contaminants on bald eagles and other fish-eating birds, annually monitor contamination levels in herring gulls and bald eagles, and look for evidence of impacts of new chemicals being released into the environment on fish.

East Lansing Field Office Contaminants biologists 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.

Helping Our National Wildlife Refuges

East Lansing Field Office Contaminants biologists help our Refuges investigate whether land they are considering purchasing has contamination issues. We also assist in cleaning up contamination on land that is already part of the Refuge system. We are currently assisting Refuges in investigating and improving Grassy Island, now a part of the Detroit River International Wildlife Refuge. In the past, the Army Corps of Engineers used the island as a disposal site for contaminated material dredged primarily from the Rouge River.
