Emerging Contaminants: Challenges in Federal Detection, Analysis and Response

Room: Otis   4:00-5:30 PM

Chair(s): Andrew Rak



M4-G.1  16:00  The Federal and State Response to Identification, Management, and Response to Emerging Contaminants. Rak A*, Gibb S; Noblis, Falls Church, VA USA   andrew.rak@noblis.org

Abstract: Emerging contaminants pose a significant public health and environmental issue of growing concern to the public. This presentation provides an overview of the growing interest in emerging contaminants across the federal and state government. The federal/state response ranges from regulatory to science/research and other agencies that perform vital tasks in the public interest. Chemicals that are not regulated are being identified in human bio-monitoring programs and in environmental media; however, the significance of the results is often unknown. The current response is geared largely towards identification of emerging contaminants with only a limited focus on management and response. The long-lead time necessary for meaningful research to improve decision-making means that early detection is important. However, the federal government’s response to emerging contaminants should be better coordinated across federal agencies to allow for not only early detection but also a health protective response. The federal/state response must provide for a credible gathering and vetting of information to develop appropriate societal responses. Federal and state management of emerging contaminants must be based on a science-based process that uses all available information while making plans to integrate new data as they become available. Identification of data gaps in the current process will be helpful in forming more integrated responses.

M4-G.2  16:20  Overview of an Emerging Contaminants Program and the Role of Chemical Ranking. Gibb SK*; Consulting   steve.gibb@noblis.org

Abstract: The Emerging Contaminants Directorate within the DoD's Office of the Secretary of Defense has innovated rigorous methods for assessing the environmental and operational impact of materials or chemicals for which new risk information is emerging or where changes are imminent in their regulatory status. Using a three-stage process entitled "Scan, Watch, Action," the Directorate gathers environmental, safety and regulatory information about emerging contaminants and assesses their uses by the Department. Chemicals or materials that have DoD applications and that may strongly impact cleanup, research, safety/health, disposal and handling, and readiness are subjected to increased levels of scrutiny. If new action is warranted, chemical ranking and substitution systems are often used to ensure DoD missions can be sustained and to reduce reliance on high-toxicity materials.

M4-G.3  16:40  DOD’s emerging contaminants response to perchlorate, hexavalent chromium and naphthalene . Hulla JE*; US Army Corps of Engineers   janis.e.hulla@usace.army.mil

Abstract: Emerging contaminants (ECs) are of interest to the Department of Defense (DOD) in the context of their potential to impact public health, occupational health, the environment, and/or national security. The potential impacts to DOD functions due to changing regulatory status of each, perchlorate, hexavalent chromium (CrVI) and naphthalene, were assessed by the Emerging Contaminants Directorate. The results indicated the potential for significant mission impacts and the Directorate is organizing integrated risk management responses. With regard to naphthalene; two Army Small Business Innovative Research Projects are underway that will apply new sensor technologies to the development of a naphthalene dosimeter. The goal is to generate data that will inform new occupational health protections and fill data gaps in the naphthalene human health risk assessment. Additionally, the Air Force is conducting formulation research aimed at understanding the amount of naphthalene in fuels and identifying opportunities for reducing naphthalene exposures from fuel-related emissions. With regard to perchlorate; environmental sampling continues and response actions are underway or completed. In California for example, 924 sites have been reviewed and prioritized. Also, perchlorate has been replaced by black powder in simulators that account for approximately 70% of perchlorate annually used in Army training contexts and DOD continues to invest in perchlorate treatment and substitution R&D. With regard to CrVI; current risk management investments include implementation of new environmental management systems to track regulatory compliance and investments in testing and evaluating alternatives to CrVI. Future risk management investments are being formulated.

M4-G.4  17:00  Evaluating Emerging Conaminant Issues Within DoD. Pitrat CA*, Hutchens SL, Markiewicz ME, Rak A; U.S. Army Center for Health Promotion and Preventive Medicine   tony.pitrat@us.army.mil

Abstract: Emerging Contaminants (ECs) can affect human health and safety, readiness and mission accomplishment, acquisition, operation and maintenance of Department of Defense (DoD) assets, and the DoD cleanup program. The Office of the Secretary of Defense (OSD) has established an EC Directorate to address emerging contaminant issues. The EC Directorate has developed, in conjunction with the Military Services, EC “watch” and “action” lists. This presentation will provide examples of how ECs have been assessed using a phased process and the results fo two years of assessments. How risk drivers affect the DoD functional areas will be discussed, and the speaker will summarize EC issues and ongoing activities of DoD's Emerging Contaminants Directorate.
