He conducts impact assessments, manages field work and laboratory experiments, and analyzes ecological data, serving as Lead Ecological Risk Assessor and/or Project Manager at several high-profile Superfund and RCRA sites nationwide to assess and quantify the effects of industrial chemicals on aquatic and terrestrial ecological receptors, characterizing impacts to ecological communities on multiple levels of biological organization, developing comprehensive conceptual models and identifying exposure effect profiles. He has worked on significant national projects such as the Bonita Peak (CO) Mining District toxic mine release and the Deepwater Horizon oil spill in the Gulf of Mexico.

J.C. King

J.C. has more than 40 years of experience in planning, performing, and overseeing activities related to Munitions and Explosives of Concern (MEC), Munitions Constituents (MC), Unexploded Ordnance (UXO) and Material Presenting a Potential Explosive Hazard (MPPEH). A retired US Army Colonel (Ordnance Corps), he has performed analysis and developed policy at the Army and Department of Defense level related to: munitions-life-cycle management; explosives and chemical safety; unexploded ordnance (UXO); waste military munitions (including discarded military munitions); underwater munitions; the conduct of munitions responses (the cleanup of munitions and explosives of concern, to include chemical munitions); support of explosives and munitions emergencies; and sustainable range management. He has been the Army lead for development of policy governing DoD's Military Munitions Response Program (MMRP), DoD's Implementation of the Environmental Protection Agency's Military Munitions Rule, the Military Munitions Response Prioritization Protocol (32 CFR, Part 179) and its accompanying training program and primer; and DoD and Army policy for the management of MPPEH. He has also been responsible for developing both DoD explosives safety criteria governing UXO, the processing and management of MPPEH, munitions responses; and the Army's 3Rs (Recognize, Retreat, Report) Explosives Safety Education Program. He provides MEC technical support to EPA regions across the country. JC holds an MA in Human Resource Management from Webster University and a BA in Social Services from Temple University.

Ann Schnitz

Ann Schnitz

Dr. Ann Schnitz is an environmental toxicologist/risk assessor with three decades of experience performing, managing, and developing numerous human health and ecological risk assessments for various governmental and commercial clients under state and federal jurisdictions. She has written and reviewed human health and ecological risk assessments under the auspices of RCRA, CERCLA, SDWA, TSCA, CAA, and other tribal, federal, state and local regulatory programs for contaminated sites (Superfund, refineries, manufacturing facilities, vapor intrusion sites, manufactured gas plants, e.g.), and participated in litigation support, communications and negotiations. These risk assessments have involved a variety of media (soil, groundwater, surface water, ambient air, indoor air, vapor intrusion) and a range of constituents, including: total petroleum hydrocarbon, pesticides, solvents, metals, PAHs, PCBs, and explosives. She has nationwide experience in planning for defensible sampling, and assessing data usability and integrity to support human health and ecological exposure, as well as the fate and transport of contaminants in environmental systems. She has extensive experience implementing modeling including Johnson and Ettinger (J&E) and EPA/ASTM exposure equations. Ann holds a PhD in Toxicology from Rutgers University and an MS in Toxicology and a BA in Biology from New York University.
