Standard Methods for the Examination of Water and Wastewater is best described as:

• A. A regulatory publication issued by the EPA.
• B. A publication that includes hundreds of analytical techniques for water quality.
• C. A safety manual for laboratories.
• D. A training program for wastewater operators.

Answer: (B)

The main idea here is recognizing that Standard Methods is a comprehensive reference of analytical procedures used to assess water quality. It’s a collaboratively published resource that catalogs hundreds of validated techniques for analyzing drinking water, wastewater, and natural waters, with detailed methods, quality control guidance, and reporting practices. Labs rely on it to perform consistent, comparable measurements across parameters such as chemistry, microbiology, and physics.

It isn’t a regulatory publication issued by the EPA, nor a safety manual for laboratories, nor a training program for operators. While regulators may reference methods from Standard Methods, the book itself serves as a collection of standardized analytical procedures, not a rule or training course.
