At different times and for various reasons,
it may be desirable to sample effluent from a wastewater treatment system.
In order to be accurate, especially to
determine system performance, any wastewater sampling must follow specific procedures and
guidelines. Specific sampling parameters and procedures are described in
METHODS FOR THE EXAMINATION OF WATER AND WASTEWATER, published by American
Public Health Association, American Water Works Association and Water
Federation. THE CODE OF
FEDERAL REGULATIONS, TITLE 40, PROTECTION OF ENVIRONMENT, published by the Office of the Federal Register, outlines how
samples must be analyzed and evaluated to be considered valid by regulatory agencies.
SAMPLING FOR PROCESS AND QUALITY CONTROL, MANUAL OF PRACTICE NO.
OM-1, published by the Water Environment
Federation, provides specific instructions on sampling techniques and the
conclusions that can be drawn. In order to properly sample water or wastewater flows and
draw accurate conclusions, all of these procedures must be strictly followed.
