The United States Environmental Protection Agency (EPA) maintains and approves test methods, which are approved procedures for measuring the presence and concentration of physical, chemical and biological contaminants; evaluating properties, such as toxic properties, of chemical substances; or measuring the effects of substances under various conditions.
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 ...
The EPA National Exposure Research Laboratory can designate a measurement device using an established technological basis as a Federal Reference Method (FRM) to certify that the device has undergone a testing and analysis protocol, and can be used to monitor NAAQS compliance.
The Environmental Technology Verification (ETV) Program of the Environmental Protection Agency (EPA) in the United States develops testing protocols and verifies the performance of innovative environmental technologies that can address problems that threaten human health or the natural environment.

The United States Environmental Protection Agency (EPA) issues Effluent Guideline regulations for categories of industrial sources of water pollution under Title III of the Clean Water Act (CWA). [1] The standards are technology-based, i.e. they are based on the performance of treatment and control technologies (e.g., Best Available Technology ...
The EPA's Good Laboratory Practice Standards (GLPS) compliance monitoring program guarantees the accuracy and reliability of test data submitted to the Agency to support pesticide product registration under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), section 5 of the Toxic Substances Control Act (TSCA), and in accordance ...
The EPA estimates the annual benefit of the new rule at $5.4 billion to $5.9 billion through 2042. “These standards are ambitious and comprehensive and really reflect the kind of reductions ...
The need for development of more advanced statistical methods, and uniformity in using these methods by regulators has been made apparent in literature. [ 8 ] Scientific methods for determining acute and chronic toxicity to organisms are inherently imperfect and non-uniform throughout the field of research, and the most useful tool for decision ...
