CRESP Amchitka Expedition: A Model for Multi- and Interdisciplinary Research into Radionuclide Contamination of the Marine Environment Presenter- Conrad (Dan) Volz, DrPH, MPHAmchitka Project DirectorConsortium for Risk Assessment with Stakeholder Participation (CRESP) Scientific DirectorCenter for Healthy Environments and CommunitiesAssistant ProfessorUniversity of Pittsburgh Graduate School of Public Health

  2. Paper Authors: Conrad Volz, DrPH, MPH, Barry Friedlander, MD, MPH, Charles Powers, PhD, Joanna Burger, PhD, David Kosson, PhD, Michael Gochfeld, MD, PhD, David Barnes, PhD, Lisa Bliss, MLS, Larry Duffy, PhD, Stephen Jewett, PhD, Janet Horsch, MLS, MFA, Mark Johnson, PhD, Michael Stabin, PhD, CHP, Martyn Unsworth, PhD, and Vikram Vyas, PhD

  3. Underground Nuclear Tests on Amchitka Island • 1965—Long Shot80 Kilotons • 1969—Milrow1 Megaton • 1971—Cannikin 5-8 MegatonsLargest USA underground test Nuclear Tests on Amchitka Account for 16% of all United States Nuclear Test Explosion Energy.

  4. Ocean surface Ocean surface Amchitka Island Transport of Radionuclides to Marine Areas Cannikin Lake Possiblechimney transport Intertidal/subtidal Collapsed chimney Benthic Deep water benthic Test shot Leakage transport Freshwater lens Saltwater layer

  5. Location of Amchitka Island 800 km southeast of Komandorskiy Ostrova 1200 km east of Petropavlovski-Kamchatskiy KiskaIsland

  6. Reasons for Concern • Area Supports Robust Biological Productivity—Fishery for USA, Canada, Japan, Korea and Russia • High Rate of Seismicity • Movement of Islands • Plate Tectonics • Discharge of Radionuclides by Hydrogeological Processes

  7. Expedition Purpose 1. Determine whether there is any current threat to human health and the environment from release into the Island's sea waters from nuclear tests shots at Amchitka. 2. Establish a baseline of biological and physical data that should aid in the development of a long-term stewardship plan.

  8. University/Community-Based Participatory Research • Stakeholders • Department of Energy, National Nuclear Security Agency (Responsible Party) • United States Fish and Wildlife Service (Landowner and Natural Resource Trustee) • State of Alaska (State of Record, ADEC) • Aleutian Pribilof Island Association (Subsistence and Lifestyle Protection) • Universities • University of Pittsburgh • Rutgers University • UMDNJ • University of Alaska, Fairbanks • University of Alberta

  9. Confounders of Study • Russian Nuclear Waste and Nuclear Naval Reactor Disposal • CS 137 Generator lost in Sea of Japan • 14 Nuclear Submarines with Damaged Fuel Rods Scuttled in the Kara Sea • Nuclear Icebreaker Lenin Scuttled in Artic Ocean • Disposal/Leakage of Nuclear Waste from Production Facilities and Naval Yards on Kamchatka, specifically Petropavlovsk-Kamchatsky

  10. Physical Expedition June 6 to June 23 • Magnetotelluric Measurements (Land) • Side Scan Sonar (Sea Bathymetry) • Multibeam Sonar (Sea Bathymetry) • Geographic Positioning Systems • Conductivity/Density/Temperature Probe • Water and Sediment Sampling • Ambient and Wipe Sample Radiation Analysis

  11. CTD and Biological Collection Stations Along Predetermined Transects

  12. Multibeam Sonar Drop Long Shot Tows

  13. MT Survey Stations on Island Transects through Blast Sites

  14. Biological Collections June 23- July 22 Amchitka (Experimental Sites) Cannikin Transects Milrow Transects Long Shot Transects Kiska Island ( Reference Site)

  15. Intertidal Alaria nana Contaminants of Concern Anthropogenic Actinides = Am-241, Pu-238, 239, 240, U-236 Bomb Detonation/Nuclear Power = Cs-137, Eu-152, Co-60, Sr-90, I-129, Tc-99. Natural Actinides = U-234, 235 and 238

  16. Trophic Levels Low Sea Urchins, Limpets, Rock Jingle, Blue Mussel, Ulva, Rock Greenling, Alaria nana and fistulosa High Black Rockfish, Tufted Puffin, Eagle, Pacific Cod, Halibut, Octopus, Sea Lion

  17. Applications of the Supercourse to the Understanding and Control of Contamination from Legacy Cold War Military Production - Forum for collaboration, teaching, distribution of data and information and alerts relative to cross-boundary issues of control of Cold War Legacy contamination.- Research into and multi-national publication of results from legacy nuclear waste sites both in the USA and Russia, including facilities, which pose a catastrophic potential to fishing grounds in the Kara Sea and Arctic Ocean.- Testing and publication of the suitability, reliability and sustainability of engineering and institutional controls at former Cold War nuclear production sites. - The development of lectures regarding the Public Health dimensions of nuclear production in “new nuclear nations” such as Iran and North Korea and possible “weapons of mass destruction” that can result from nuclear proliferation. - Research, publication, lectures and symposium on other Cold War contaminants such as organohalogen substances (i.e., PCB’s) and heavy metals, which may act as endocrine disruptors and modifers.

Selected Results Excerpted from; AMCHITKA INDEPENDENT SCIENCE ASSESSMENT:Biological and Geophysical Aspects of Potential Radionuclide Exposure in the Amchitka Marine Environment Released, August 1, 2005, Anchorage Alaska CRESP Website - http://cresp.org/ Editors C.W.

  19. Selected Results No fissile material or products found in ocean sediments. Greater subsurface pore volume was present than assumed by earlier studies, suggesting very long travel times for radionuclide migration from the test shots to the marine environment – 1400 to 4700 years for Long Shot. No radiation survey data above background was found on land or sea. Expedition personnel radiation dosimetry was statistically the same as control dosimeters kept on Adak Island.

  20. Selected Results No generalized, large scale areas of freshwater discharge were detected. No underwater fractures or faults were seen in the surveyed areas. Areas of offshore slumping and compression were seen. Significant areas of offshore sediment were found, indicating a possible matrix for radionuclide deposition

  21. Selected Results The foods consumed by humans are safe with respect to radionuclides, and levels of radionuclides are well below published human health risk guidance levels. I-129, Co-60, Eu 152, Sr-90 and Tc-99 in all biota analysis were below the minimum detection level. • For Cs-137 high trophic level organisms (Sea Lion, Octopus, Pacific Cod, Halibut, Eagle) at both experimental and reference sites had higherlevels than those lower on the food chain (all others), (X2 = 9.53, P < 0.02). • There were no significant differences for anthropogenicactinide isotopes (Am-241, Pu-238, 239, 240, U-236) between Kiska and Amchitka, except for Pu 239,240 in Kelp (X2 = 4.32, P= .04).
