Metals and Mining
USEPA, Coeur d’Alene Basin, Idaho
Lead terrestrial ecological risk assessor for the over 1500 square mile Coeur d’Alene Basin (2001-2010). Used a weight-of-evidence approach
to evaluate risks from lead and other heavy metals to 42 bird and mammal species, four amphibian species, and the terrestrial plant and soil invertebrate communities. Developed multiple models based on site-specific data to allow for more robust estimation of risk. Coordinated ecological risk efforts with natural resource trustees developing the NRDA. Provided continued support during the National Academy of Sciences review of the Coeur d’Alene risk assessment/remedial decision process.
USEPA, Anaconda/Yerington Mine, Nevada
Lead ecological risk assessor providing PRP oversight at a mining and mineral processing facility (2007-2010). Performed screening-level assessment of leachate ponds with low pH and high metals for risk to wildlife, integrated recent research on wildlife exposure to leachate pond water to accurately demonstrate risk.
USEPA, Asarco/Hayden Smelter, Arizona
Lead ecological risk assessor for copper smelting and mineral processing facility (2004-2008). Assessed risks associated with tailing ponds and contaminated soil, sediment and surface waters in adjacent Gila River, including habitat for large population of federal endangered species. Integrated extensive US Fish and Wildlife Service data that showed minimal effects to resident birds, mammals, and aquatic biota.
USEPA, Lava Cap Mine, California
Lead ecological risk assessor for abandoned silver and gold mine (2000-2005). Used a weight-of-evidence approach to evaluate baseline risks from arsenic, lead and other heavy metals to terrestrial and aquatic ecological receptors. Data included site-specific terrestrial and aquatic bioassays, site-specific bioaccumulation data, and field surveys.
Ontario Ministry of the Environment, Deloro Mine, Ontario
Senior ecological risk assessor for abandoned silver and gold mine in Ontario, Canada (2000-2008). Used a weight-of-evidence approach to
evaluate baseline risks from metals to terrestrial and aquatic ecological receptors in the 500 acre site. Data included site-specific terrestrial and
aquatic bioassays, site-specific bioaccumulation data, and field surveys.
