Governing body	United States Department of Energy

Fernald Preserve is a restored conservation area on a former industrial site in western Hamilton County, Ohio. The site transitioned from a 20th-century uranium-processing plant to a National Priority List remediation and ecological restoration project, culminating in long‑term stewardship as a public nature preserve. The property now combines restored prairie, wetlands, forest, and riparian corridors with interpretive facilities for visitors from Cincinnati and surrounding communities.

History

The site originated as the Feed Materials Production Center, established during World War II under the Manhattan Project to process uranium for weapons programs associated with Oak Ridge National Laboratory and Argonne National Laboratory. Through the Cold War, operations tied to the United States Atomic Energy Commission and later the Department of Energy continued production and material storage, linking the property to national nuclear policies and projects such as the early nuclear weapons complex and procurement for Los Alamos National Laboratory. Routine industrial processes, waste handling, and on‑site disposal created contamination that led to investigations under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 and placement on the National Priorities List administered by the United States Environmental Protection Agency.

Public scrutiny, advocacy by regional stakeholders including Hamilton County officials, and litigation with contractors and federal agencies shaped remediation timelines. Partnerships with the Ohio Environmental Protection Agency and community organizations influenced land‑use planning, while technical oversight drew on expertise from institutions such as Battelle Memorial Institute and academic partners at University of Cincinnati and Miami University. The transition from industrial complex to conservation area reflects broader shifts in site reuse seen at other former Cold War landscapes like Rocky Flats National Wildlife Refuge and Hanford Site.

Environmental Cleanup and Remediation

Remediation at the site followed protocols under the Resource Conservation and Recovery Act and CERCLA processes overseen by the United States Environmental Protection Agency. Characterization of soil, groundwater, and on‑site disposal cells required radiological surveys referencing standards developed by bodies such as the Nuclear Regulatory Commission and the International Atomic Energy Agency. Major remedial actions included consolidation of low‑level radioactive residues into engineered disposal cells, excavation and removal of contaminated soils, groundwater pump‑and‑treat systems, and long‑term monitoring plans coordinated with the Department of Energy Office of Legacy Management.

Engineering controls employed geosynthetic liners, multi‑layer capping systems, and hydrologic diversion measures modeled after projects at other remediation sites like Savannah River Site and legacy facilities to minimize leachate and erosion. Natural attenuation strategies and phytoremediation pilots complemented structural remedies, with validation testing carried out by laboratories collaborating with Environmental Protection Agency regional offices and university research centers. Institutional controls, land‑use covenants, and stewardship plans were established to manage residual risk, surveillance, and maintenance into perpetuity.

Ecology and Habitats

Restoration emphasized reconstruction of native ecosystems typical of southwestern Ohio glacial plains, focusing on tallgrass prairie, wet meadow, oak‑hickory woodland, and riparian habitat along tributaries feeding the Great Miami River. Seed mixes and plantings were selected in consultation with specialists from The Nature Conservancy and academic partners such as Ohio State University. Habitat creation supports fauna including grassland birds monitored under programs analogous to the North American Breeding Bird Survey, pollinators surveyed through cooperative projects with Xerces Society approaches, and wetland amphibians of conservation concern documented by state natural heritage inventories.

Ecological management uses adaptive strategies drawn from restoration ecology literature and comparative sites like Prairie State Park and Cuyahoga Valley National Park. Invasive species control targets non‑native woody and herbaceous plants using integrated pest management guided by state conservation guidelines from the Ohio Department of Natural Resources. Long‑term biological monitoring, including vegetation transects and wildlife camera surveys, informs successional management and biodiversity objectives linked to regional initiatives such as the Great American Grasslands conservation movement.

Public Access and Recreation

As a public preserve, the site provides trails, overlooks, and interpretive exhibits to educate visitors about industrial history, remediation, and restoration. Connections to metropolitan recreational networks enable access from Cincinnati and suburban communities via roadways and trail linkages coordinated with Hamilton County Engineer's Office planning. Programming includes guided walks, birding events aligned with organizations like Audubon Society chapters, and school outreach partnerships with local districts and universities such as Miami University for environmental education.

Facilities accommodate passive recreation—hiking, wildlife observation, and seasonal programming—while institutional controls restrict activities that could breach engineered caps or monitoring zones. Interpretive signage and visitor materials reference historical milestones tied to the Manhattan Project and regional Cold War heritage comparable to exhibits at National Museum of Nuclear Science & History and other interpretive centers. Volunteer stewardship and citizen science projects engage community groups, conservation corps, and nonprofit partners.

Management and Oversight

Long‑term stewardship is managed by the Department of Energy Office of Legacy Management in coordination with the United States Environmental Protection Agency and the Ohio Environmental Protection Agency. Site management integrates performance monitoring, maintenance of engineered controls, ecological management, and community engagement under legal frameworks such as CERCLA remedies and state environmental statutes. Oversight committees and technical review boards include federal and state regulators, academic advisors, and local stakeholders drawing on precedents from other remediation‑to‑conservation projects like Rocky Mountain Arsenal National Wildlife Refuge.

Funding and operational responsibility involve federal allocations, cooperative agreements with county agencies, and partnerships with conservation organizations for habitat management and public programming. Periodic Five‑Year Reviews, environmental monitoring reports, and public meetings provide transparency and accountability to stakeholders including regional municipalities, academic institutions, and nongovernmental organizations.
