Dr. Marty Huehner, a senior member of the EnviroScience scientific staff and a distinguished academic and researcher, began his association with ES in 1998 as a consulting scientist. He is a state and USFWS approved mussel surveyor in numerous states including OH, PA, KY, WV, IA, IL, MO, MI, IN, and WI and has been conducting freshwater mussel surveys since 1971.  

Dr. Huehner has focused extensively on field surveys of mussel populations, field and laboratory studies of freshwater mussel ecology, and has worked on some of the largest and most successful mussel relocation projects in North America. In Missouri, he was first to report the presence and distribution of aspidogastrid trematode parasites in freshwater mussels from that state; and in Ohio, he has been credited with identifying several populations of state and federally-protected mussel species, including the salamander mussel and the clubshell mussel.

He is also a participant in the USFWS project locating reproductive individuals of the nearly extinct Purple Catspaw Mussel, Epioblasma obliquata obliquata in Killbuck Creek, Ohio. As an expert testifying witness, he has testified in court as an authority on stream ecology and freshwater mollusks. His publications appear in accredited journals including the Journal of Invertebrate Pathology, the Ohio Journal of Science, and the Journal of Parasitology. In 2007, Dr. Huehner retired from academia and now works full time with ES where he has been a project manager and malacologist on mussel surveys conducted in large rivers in Arkansas, Missouri, Illinois, Kentucky, West Virginia, Ohio, and Pennsylvania. He has also conducted mussel surveys or translocation projects in many smaller streams in these and other states.

Few environmental firms in the country retain EnviroScience’s degree of scientific know-how, talent, and capability under one roof. The diverse backgrounds of our biologists, environmental engineers, scientists, and divers enable us to provide comprehensive in-house services and an integrated approach to solving environmental challenges—saving clients time, reducing costs, and ensuring high-quality results. EnviroScience was created with the concept that we could solve complex problems by empowering great people. This concept still holds true today, as our scientists explore the latest in environmental legislation and regulations and incorporate the most up-to-date technology to gather and report data.

EnviroScience expertise includes but is not limited to: aquatic survey (including macroinvertebrate surveys and biological assessments); ecological restoration; ecological services (including impact assessments, invasive species control, and water quality monitoring);  emergency response; engineering and compliance services; endangered mussel surveys; laboratory and analysis; stormwater management; threatened and endangered species; and wetlands and streams (including delineation and mitigation). Further, EnviroScience is one of the few biological firms in the country that is a general member of the Association of Diving Contractors International (ADCI) and offers full-service commercial diving services.
