The Indiana Drinking Water Laboratory Certification Program is based on the EPA Manual for the Certification of Laboratories Analyzing Drinking Water; Criteria and Procedures Quality Assurance, 5th Edition (EPA 815-R-05-004), January 2005 (EPA Manual). The EPA Laboratory Certification Manual information site is at: http://water.epa.gov/scitech/drinkingwater/labcert/index.cfm.
The EPA Laboratory Certification Manual describes the minimum requirements for the Drinking Water Laboratory Certification Program implementation procedures, laboratory procedures, and technical criteria laboratories must meet to analyze drinking water compliance samples. Chapter IV of the EPA manual lists the Critical Element for Chemistry and Chapter V of the EPA manual lists the Critical Elements for Microbiology.
