Biological - Benthic Macroinvertebrate Count

Place a mark next to each type of organism that is observed. Add the marks in each column and multiply by the index value (1, 2 or 3). Sum the totals in each column to determine the water quality rating for the stream. Good water quality is indicated by a variety of organisms, with no one kind making up the majority of the sample.
