GENERAL LABORATORY QUALITY ASSURANCE/QUALITY- CONTROL PRACTICES
An overview of analytical methods,
training policies, safety, laboratory maintenance, sample management, and data
documentation is given in this section.
Analytical Methods
The
methods used by the Ohio Water Microbiology Laboratory (OWML) can be categorized
into three groups: compliance, official, and research. The United States
Environmental Protection Agency (USEPA) and others in the research community are
continuously developing new methods for detecting and quantifying
microbiological pathogens and indicators in water; therefore, several types of
methods for target organisms may be currently in use at the OWML.
Compliance methods are those published by USEPA in the Federal Register and are
used to determine compliance with standards for protection of public health in
swimmable or drinkable waters. Analytical methods for fecal-indicator bacteria
are often in this group because they are straightforward, quantitative, and
routinely used.
Official methods are those noncompliance methods published by water-analysis
authorities such as American Public Health Association, the U.S. Environmental
Protection Agency, or the USGS. Official methods should be well established,
have known levels of bias and variability, and be relatively easy to apply in
field operations or have holding times long enough to allow shipping to a
central laboratory for analysis.
Research methods are unpublished methods that are currently being testing to
establish QA/QC practices and determine applicability to ambient monitoring
programs. |
