Central Hazardous Materials Fund (CHF) Sites

CHF cleanup sites include parks, abandoned mines, wildlife refuges, old industrial sites, and landfills, and military use areas across many Department of the Interior bureaus including the National Park Service, the Fish and Wildlife Service, the Bureau of Land Management and the Bureau of Indian Affairs.

Accomplishments at CHF sites

In many cases, CHF funded sites provided increased access to outdoor recreation after cleanup is completed. The US Fish and Wildlife Service Leavenworth National Fish Hatchery, located 80 miles east of Seattle, has undergone removal of lead-contaminated soil from an abandoned sports shooting range. The formerly contaminated area is being converted to a children’s fishing pond. To find out more about Leavenworth, please visit the Leavenworth Story Map.

CHF site cleanup also benefits wildlife and environmental quality. Midway Atoll National Wildlife Refuge, located at the northern end of the Hawaiian Archipelago, is home to one of the world’s largest populations of seabirds. This former military site has also suffered lead contamination, which has damaged wildlife populations dramatically. The cleanup of contaminants funded by CHF has facilitated a restoration of native bird populations. To learn more about the Midway Atoll, please visit the Midway Atoll Story Map.
