  1. Upper Columbia RI/FS: Creating a Citizen’s Guide to Human Health Findings Lake Roosevelt Forum Laura Buelow, Ph.D., R10 U.S. EPA, Hanford Project Office

  2. EPA Project Partners • 2007 EPA MOA with: • Department of Interior – 6 bureaus • NPS, USGS, FWS, BOR, BIA, BLM • Colville Tribes • Spokane Tribe • WA Dept of Ecology • WA Dept of Health • Citizens for a Clean Columbia (TAG)

  3. RI/FS Human Health Studies • Recreational use survey • Tribal consumption survey • Completed studies • Fish tissue • Surface water • Beaches • Ongoing Studies • YAM/Bossburg • Upcoming Studies • Upland soils • Residential soil sampling • Human Health Risk Assessment estimated to be complete 2017-2018

  4. Air • Teck performs monitoring in Northport (started in 1994) • No concerns for full time residents

  5. Beaches • 43 beaches sampled to date • 15 beaches sampled by EPA in 2005 • 33 others sampled by Teck 2009 - 2011 • EPA did screening-level evaluation, distributed results in Fact Sheet at LRF meeting in April 2012 • Bossburg Flats closed due to high lead levels • Evans Campground and “Swimming Hole” near Sheep Creek had slightly elevated levels of lead and arsenic, respectively, above screening levels, but considered safe for recreation

  6. Beaches

  7. Surface Water Sampling • Sampling 2009, 2010 repeated 3 times to capture seasonal variability • 10 transects starting in Canada above smelter, surface & near bottom samples • 90 or more locations (~2500 samples) • “Disturbed” surface water samples at recreational beaches • > 400 analytes -- including metals, pesticides, PBDEs, PCB congeners • Very few undisturbed samples exceeded drinking water standards (DWS) • Disturbed samples had some results above DWS for lead and secondary MCLs for pH, aluminum, iron and manganese

  8. Fish Tissue • More than 2,300 fish collected Nov 2009 • 3 size classes, 13 species • Metals, exotic metals, dioxins / furans, PCBs, PBDEs, PAHs, pesticides, SVOCs

  9. FSCA 1 FSCA 2 FSCA 3 Fish Sample Collection Areas FSCA 4 FSCA 6 FSCA 5

  10. Updated Fish Advisory from Washington Department of Health, July 2012 • Specific to Lake Roosevelt • Mercury and PCBs

  11. Soil • Residential soil sampling • Upland soil sampling • Sampling plans in preparation, sampling planned for 2014 • Assessing Potential Health Risks of Metals in Residential and Recreational Area Near the U.S.-Canadian Border (afternoon session)
