  2. Effluent guidelines - Wikipedia

    en.wikipedia.org/wiki/Effluent_guidelines

    EPA has published many methods in its regulations, [4] and has approved the use of other methods published by peer-reviewed sources, such as Standard Methods. [5] Although the effluent limitations are based on the performance of control and treatment technologies (and not the impacts to receiving waters), the regulations do not require ...

  3. New Source Performance Standards - Wikipedia

    en.wikipedia.org/wiki/New_Source_Performance...

    New Source Performance Standards (NSPS) are pollution control standards issued by the United States Environmental Protection Agency (EPA). The term is used in the Clean Air Act Extension of 1970 (CAA) to refer to air pollution emission standards, and in the Clean Water Act (CWA) referring to standards for water pollution discharges of industrial wastewater to surface waters.

  4. Water testing - Wikipedia

    en.wikipedia.org/wiki/Water_testing

    Wastewater analysis. All facilities in the United States that discharge wastewater to surface waters (e.g. rivers, lakes or coastal waters) must obtain a permit under the National Pollutant Discharge Elimination System, a Clean Water Act program administered by EPA and state agencies. The facilities covered include sewage treatment plants ...

  5. Best available technology - Wikipedia

    en.wikipedia.org/wiki/Best_Available_Technology

    In the development of the effluent standards, the BAT concept is a "model" technology rather than a specific regulatory requirement. The U.S. Environmental Protection Agency (EPA) identifies a particular model technology for an industry, and then writes a regulatory performance standard based on the model. The performance standard is typically ...

  6. EPA Methods - Wikipedia

    en.wikipedia.org/wiki/EPA_Methods

    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.

  7. Toxicity characteristic leaching procedure - Wikipedia

    en.wikipedia.org/wiki/Toxicity_characteristic...

    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 ...

  8. Cold vapour atomic fluorescence spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Cold_vapour_atomic...

    Various analytical methods approved by the United States Environmental Protection Agency (EPA) for measuring mercury in wastewater are in common use. EPA Methods 245.7 and 1631 are commonly used for measurement of industrial wastewater using CVAFS. [2] [3]

  9. Effluent - Wikipedia

    en.wikipedia.org/wiki/Effluent

    Effluent is defined by the United States Environmental Protection Agency (EPA) as "wastewater–treated or untreated–that flows out of a treatment plant, sewer, or industrial outfall. Generally refers to wastes discharged into surface waters". [ 1 ]
