Biological field and laboratory methods for measuring the quality of ...

PREFACE
This manual was published under Research Objective Achievement Plan
1BA027-05AEF, "Methods for Determining Biological Parameters of all
Waters," as part of the National Analytical Methods Development Research
Program. The manual was prepared largely by a standing committee of senior
Agency biologists organized in 1970 to assist the Biological Methods Branch
in the selection of methods for use in routine field and laboratory work in
fresh and marine waters arising during short-term enforcement studies, water
quality trend monitoring, effluent testing and research projects.
The methods contained in this manual are considered by the Committee
to be the best available at this time. The manual will be revised and new
methods will be recommended as the need arises.
The Committee attempted to avoid duplicating field and laboratory
methods already adequately described for Agency use in Standard Methods
for the Examination of Water and Wastewater, 13th edition, and frequent
reference is made to this source throughout the manual.
