CEC has performed a variety of biological assessment studies on water bodies, including sampling, identification, and analysis of phytoplankton, zooplankton, periphyton, aquatic macrophyte, benthic macroinvertebrate, and fish communities. Our staff is proficient in implementing the U.S. Environmental Protection Agency's Rapid Bioassessment Protocols for Use in Streams and Rivers (EPA/440/4-89/001) and Macroinvertebrate Field and Laboratory Methods for Evaluating the Biological Integrity of Surface Waters (EPA/600/4-90/030).

CEC biologists are also trained and highly experienced in performing aquatic and terrestrial ecological risk assessments for sites requiring hazardous waste characterization and remediation.

CEC also owns the equipment needed for these types of surveys, including boats, electro-shockers, benthic sampling equipment, and a fully equipped biologic laboratory in support of these services.

CEC has been successful in negotiating environmental permits for sensitive ecological areas.
