Brief Method Summary
 This method describes how to process benthic macroinvertebrate samples and conduct analyses. A general discussion of sorting and identification is also provided.
Scope and Application
 This section is extracted from the complete 17-page ASTM protocol. This method describes benthic macroinvertebrate sample processing and analysis in various surface water environments.
Applicable Concentration Range
Interferences
 Carefully check rocks, sticks, shells, and other objects for attached or burrowed organisms before discarding.
Quality Control Requirements
Sample Handling
 Preserve and store in 70% ethanol organisms taken in the field or from artificial substrates and sieved with a U.S. Standard No. 30 sieve.
Maximum Holding Time
Relative Cost
 Unknown
Sample Preparation Methods
 Preserve and store in 70% ethanol organisms taken in the field or from artificial substrates and sieved with a U.S. Standard No. 30 sieve. For special studies and to retain anatomical form and structures, fix soft-bodied organisms first with 5 to 10% buffered formalin.
