Basic Laboratory Procedures for the Operator-Analyst

This publication includes laboratory procedures most often performed in wastewater laboratories and general wet chemistry procedures, activated sludge process control tests, bacteriological testing, and special sections about basic laboratory techniques and proper use of spectrophotometers and colorimetry. Each method (procedure) is broken down into easy-to-follow step-by-step directions that adhere to recommendations found in Standard Methods for the Examination of Water and Wastewater and approved U.S. Environmental Protection Agency guidelines.  The intention of the manual is to help the operator–analyst produce analytical data that are defensible, precise, and accurate for process control and permit reporting.
