Lance Fontenot, Ph.D., PWS

Lance Fontenot is a Principal Toxicologist based in Louisiana with more than 20 years of experience focused on assessing the human health and ecological effects of hazardous substance releases, and ecological impact assessment.

Lance's research and applied consulting experience includes work on the ecotoxicology of amphibians and reptiles, and the use of various organisms as bioindicators of environmental contamination. His work has involved basic research studies of the parasites, food habits, and habitat preference of aquatic snakes from wetland areas in South Louisiana. Lance's applied research consisted of studies of snakes and frogs and their parasite communities as bioindicators of environmental contamination, and the evaluation of trophic level movement of PCBs in a PCB-contaminated watershed in South Carolina.

He has performed human health and ecological risk assessments using U.S. EPA's Risk Assessment Guidance for Superfund (RAGS), and state-lead guidance and regulations. Lance has managed surface water and sediment quality assessments, bioaccumulation studies, invertebrate and vertebrate community ecology studies, wetland delineation and permitting, and ecotoxicological studies of fish, amphibians, and reptiles. He has qualified as an expert in state and federal courts in environmental toxicology, risk assessment and biology, and has provided testimony on the environmental impacts of a range of activities including oil and gas, pesticide use, and stormwater discharges in Louisiana and Texas.

To advance the state of the practice, Lance has published more than 20 articles involving ecotoxicology and other basic ecological studies. He has served as a technical reviewer for topics in ecotoxicology, aquatic toxicology, and wildlife toxicology for a number of peer-reviewed journals; and served on the editorial board for the Society of Environmental Toxicology and Chemistry's journal Environmental Toxicology and Chemistry. Lance continues to focus on the development of innovative ecotoxicological methods to evaluate environmental impacts.
