In-stream assessments of aquatic fauna are one of the three primary methods of determing effects upon water quality in receiving streams.  Headed by an environmental scientiest with a Ph.D. in Entomology, ETT holds a vast amount of experience in macroinvertebrate studies. Macroinvertebrate projects contain many facets including the following:

Scope of Work:  Years of experience provide ETT scientists with the ability to prepare Scope of Work plans for submittal and acceptance by regulators.

Sampling:  ETT's field team is highly qualified in field macroinvertebrate identification and sampling techniques.  Our team is completely equipped for qualitative sampling, multiplate samplers, light traps, and ponar grabs.

Sample Processing:  Macroinvertebrates are varied in size and often well concealed.  Our technicians are trained and experienced in recovering  the entire species population in a sample.

Taxonomic Identification:  Our staff includes qualified taxonomists who provide accurate freshwater and estuarine macroinvertebrate identification.

Data Analysis:  Our scientists are respected for their expertise, analysis and interpretation of this type of data.
