Many
benthic macroinvertebrates are relatively sessile in their life cycle within a
water matrix. Assemblages of benthic macroinvertebrates are made up of species
that have a broad range of trophic levels and pollution tolerances. Using these
known facts, a benthic macroinvertebrate analysis can give an assessment of
site-specific impacts of point and non-point pollution within the aquatic
environment. This analysis is an excellent tool for monitoring total maximum
daily loads (TMDLs), watershed and water quality studies. Benthic
macroinvertebrate analysis follows USEPA procedures in Rapid Bioassessment
Protocols for Use in Wadeable Streams and Rivers, second edition.
