Hazardous waste in the United States is a category of dangerous refuse whose mismanagement poses significant risks to public health and the environment. Its control is primarily governed by a stringent federal framework established in the 1970s, most notably the Resource Conservation and Recovery Act. The United States Environmental Protection Agency is the primary federal body overseeing its regulation, while major cleanup efforts are directed through the Superfund program.

Definition and classification

A waste is deemed hazardous under federal law if it exhibits characteristics like ignitability, corrosivity, reactivity, or toxicity, or if it is specifically listed by the EPA. The agency maintains several lists, including the F-list for non-specific source wastes, the K-list for source-specific wastes from industries like petroleum refining, and the P-list and U-list for discarded commercial chemical products. Certain wastes, such as household hazardous waste and some industrial waste streams, are exempted or subject to less stringent rules. The Department of Transportation also classifies hazardous materials for transport under its own criteria, which often align with EPA definitions.

Regulation and legislation

The cornerstone of hazardous waste regulation is the Resource Conservation and Recovery Act, enacted by the United States Congress in 1976, which establishes a "cradle-to-grave" tracking system. The Hazardous and Solid Waste Amendments of 1984 significantly strengthened RCRA. For addressing historical contamination, the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 created the Superfund program and established strict liability for responsible parties. Enforcement is shared between the EPA and authorized state agencies, such as the California Department of Toxic Substances Control. Other relevant laws include the Toxic Substances Control Act and the Emergency Planning and Community Right-to-Know Act.

Generation and management

Major generators of hazardous waste include the chemical industry, manufacturing sectors, petroleum refineries, and electroplating operations. Management practices are strictly regulated, requiring treatment, storage, or disposal at permitted facilities like secure landfills, incinerators, and waste stabilization plants. The EPA encourages pollution prevention and waste minimization through initiatives like the Waste Minimization National Plan. Significant quantities of hazardous waste are also recycled, treated, or disposed of through commercial facilities operated by companies such as Clean Harbors and Heritage Environmental Services.

Environmental and health impacts

Improper disposal has led to severe environmental disasters, most famously at Love Canal in Niagara Falls, New York, which spurred the creation of Superfund. Contamination of aquifers, surface water like the Cuyahoga River, and soil can expose communities to carcinogens, neurotoxins, and endocrine disruptors. Studies of areas near major waste sites, such as Anniston, Alabama (site of Monsanto PCB contamination) and Triana, Alabama (affected by DDT), have shown elevated risks of cancer, birth defects, and other ailments. Exposure often disproportionately affects environmental justice communities.

Cleanup and remediation programs

The primary federal cleanup program is Superfund, administered by the EPA, which identifies sites on the National Priorities List for remediation. Notable long-term cleanups include the Gowanus Canal in Brooklyn, the Portland Harbor in Oregon, and the Tar Creek Superfund site in Oklahoma. The Department of Defense and the Department of Energy run separate, massive cleanup programs for contamination at former military installations like Camp Lejeune and nuclear weapons complexes such as the Hanford Site. These efforts often involve complex techniques like soil vapor extraction and pump-and-treat.

Controversies and challenges

The Superfund program has been criticized for lengthy, costly cleanups and a diminished funding source since the corporate taxes expired in 1995. Legal battles over liability under CERCLA, often involving potentially responsible parties like General Electric or Shell Oil Company, can delay remediation for decades. Emerging challenges include the management of new waste streams like per- and polyfluoroalkyl substances and electronic waste, and debates over the regulation of coal ash and oil and gas waste. The Government Accountability Office and advocacy groups like the Center for Health, Environment & Justice frequently highlight ongoing risks and enforcement gaps.
