Collection of Methods

Test Method Collection
EPA offices and laboratories, and outside organizations, have developed approved methods for measuring the concentration of a substance or pollutant.  Below are categories of methods. Learn about how methods are developed on the Method Development page. 

On this page:

  • Air and Radiation
  • Water
  • Prevention, Pesticides, and Toxic Substances
  • Research and Development - Not Approved
  • Solid Waste and Emergency Response
  • Index to EPA Test Methods

Air and Radiation

  • Air Emission Measurement Center (EMC)
  • EMC Promulgated and Proposed Performance Specifications
  • Ambient Monitoring Methods
  • Mobile Source Methods
  • Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM)

Water

  • Drinking Water Analytical Methods
  • Clean Water Act Analytical Methods

Prevention, Pesticides, and Toxic Substances

  • Analytical Methods and Procedures for Pesticides

Research and Development - Laboratory Validated

A Note about Research and Development Methods

Most of these methods are considered "laboratory validated" because they have not been formally adopted for use by a program office, nor have they been integrated into a regulatory program. However, some of these methods are in the process of being formalized.

  • Endocrine Disrupting Chemicals Research
  • Ecosystem Research
  • Health Research
  • Water Research
  • Perfluorocarbon (PFC) Methods
  • Homeland Security Research

Solid Waste and Emergency Response

  • Waste and Hazardous Waste Test Methods, Including SW-846
  • Superfund Contract Laboratory Program (CLP) Analytical Services and Methods
  • Methods and Other Standard Operating Procedures for On-Scene Coordinators (epaosc.org)
