Approved Industry-Specific CWA Test Methods

In addition to general purpose methods, the EPA has approved special purpose analytical methods. These methods were developed to work in samples or for pollutants specific to certain industrial categories. For example, methods specific to the Pharmaceutical Manufacturing and Pesticide Chemicals Effluent Guidelines categories are listed in Tables I-F and I-G, respectively, at 40 CFR Part 136.

Methods specific to other industrial categories are listed or incorporated by reference into the regulations at 40 CFR Parts 401 through 503. These include methods specific to the Pulp, Paper, and Paperboard category (40 CFR Part 430), and specific to Use or Disposal of Sewage Sludge (biosolids) (40 CFR Part 503). Industry-specific methods that are approved for compliance monitoring in the industry for which they are designated may be used for general use, if the same method is listed in Tables I-A to I-E, or I-H at 40 CFR 136.3.
