Clean Water Act Analytical Methods
EPA publishes laboratory analytical methods, or test procedures that are used by industries and municipalities to analyze the chemical, physical and biological components of wastewater and other environmental samples that are required by the Clean Water Act (CWA). Most of these methods are published in the Code of Federal Regulations at 40 CFR Part 136.
