Geochemical Environmental Research

Overview of Services

The Geochemical and Environmental Research Group (GERG) at Texas A&M University has an international reputation and has been performing high quality trace organic analyses for over 35 years. GERG has developed “trace” analytical methodologies to analyze environmental samples for a variety of compounds including organochlorine pesticides (e.g., DDT), polychlorinated biphenyls (PCBs), planar PCBs, tributyltin (active component of anti-fouling paint), dioxins/furans, organophosphate pesticides, volatile organic compounds (VOCs), photosynthetic pigments, total petroleum hydrocarbons (TPH), polynuclear aromatic hydrocarbons (PAH), PAH bile metabolites, poly-brominated diphenyl ethers (PBDE), and nutrients. GERG’s historic collaborations have led to a wide array of funding opportunities through US Fish and Wildlife, NIH, NIEHS, EPA, and the National Institute of Justice, expanding upon more traditional funding streams at NOAA and NSF. GERG has provided analytical services for a wide variety of clients ranging from governmental to private industry.

Providing access to students and university researcher open access, following instrument specific training, to our instruments in support of their respective research interests/projects is a new paradigm designed to further scientific advances at Texas A&M University.
