Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental ...
Resource Conservation and Recovery Act; Other short titles: Resource Conservation and Recovery Act of 1976: Long title: An Act to provide technical and financial assistance for the development of management plans and facilities for the recovery of energy and other resources from discarded materials and for the safe disposal of discarded materials, and to regulate the management of hazardous waste.
Toxicity of a hazardous waste is defined through a laboratory procedure called the toxicity characteristic leaching procedure (TCLP). The TCLP helps identify wastes likely to leach concentrations of contaminants into the environment that may be harmful to human health or the environment.
Hazardous waste is waste that must be handled properly to avoid damaging human health or the environment. Waste can be hazardous because it is toxic, reacts violently with other chemicals, or is corrosive, among other traits. [1] As of 2022, humanity produces 300-500 million metric tons of hazardous waste annually. [2]

Is presumed to be toxic to humans because it falls within any one of the following categories when tested on laboratory animals (whenever possible, animal test data that has been reported in the chemical literature should be used): Oral Toxicity: A liquid or solid with an LD50 for acute oral toxicity of not more than 300 mg/kg. Dermal Toxicity ...
Prior to the completion of the EPA's regulatory determination, Congress enacted the Solid Waste Disposal Act in 1980 which exempted oil field wastes under section C of RCRA unless the EPA determined that the waste was hazardous. [36] Each of the six special waste categories was the subject of separate EPA study.
Hazardous waste typically has specific definitions, due to the more careful and complex handling required of such wastes. Under US law, waste may be classified as hazardous based on certain characteristics: ignitability, reactivity, corrosivity and toxicity. Some types of hazardous waste are specifically listed in regulations. [10] [11]
