Quality Assurance/Quality Control Manual: Ohio Water Microbiology Laboratory

 

METHODS OF ANALYSIS, MEDIA AND REAGENT PREPARATION, AND ANALYTICAL QUALITY-CONTROL PROCEDURES

Methods of analysis, media and reagent preparation and storage, and analytical quality-control procedures are discussed in this section. Because microbiological analyses measure constantly changing living organisms, the methods are inherently variable. Some quality-control tools used by chemists, therefore, may not be available to the microbiologist (American Public Health Association, 1998, Section 9020 A).

References of published microbiological methods are kept in a notebook in the laboratory. Media-preparation instructions and method summaries written by the Ohio Water Microbiology Laboratory (OWML) are kept in the reference notebook and furnished as Appendices to this document.

The OWML has been working to optimize and field apply research methods that are being used in a variety of applications, including rapid assessment of recreational water quality, direct detection of pathogens, and microbial source tracking.
