Amina Pollard is an American limnologist and ecologist at the U.S. Environmental Protection Agency (EPA).[1]
Pollard leads the U.S. EPA National Lakes Assessment, which seeks to provide information on the health of lakes, ponds, and reservoirs across the United States.[2][3][4] She also currently serves on the Association for the Sciences of Limnology and Oceanography (ASLO) board of directors until 2021[5], chairs ASLO's annual awards committee[6], and is a scientific advisor to Canada's Lake Pulse research program.[7]
Education and early career
Pollard received her BA from Lawrence University in 1995 and a Master's degree from Wright State University in 1997.[8] In 2002, she received her PhD from the University of Wisconsin-Madison's Center for Limnology under the supervision of John Magnuson and Thomas Frost.[9] Pollard studied how the structure and connectedness of streams and lakes affects invertebrate communities within those systems.
After graduating from the University of Wisconsin, Pollard starting working for the EPA as a postdoctoral fellow and has remained at the EPA her entire career.[10]
Career
At the EPA, Pollard leads the National Lakes Assessment (NLA), a standardized and coordinated effort to sample lakes in the U.S.[1][2] The NLA provides publicly-available colocated biological, chemical, habitat, and human use metrics for representative lakes every 5 years starting in 2007. Comparing the 2007 and 2012 NLA sampling efforts allowed Pollard and her colleagues to determine that the proportion of "blue" lakes was declining while the proportion of "murky" lakes was increasing in the continental U.S.[11][12][3] The increase in murky lakes - an indicator of poor water quality - was due to the combined effect of increased eutrophication and dissolved organic carbon inputs from the terrestrial environment. Pollard and colleagues also determined that the murky lakes were less efficient at transferring energy up the food web (to zooplankton, for example), despite having the highest rates of primary production. The murky lakes also had the highest concentration of microcystin, which are a class of toxins produced by cyanobacteria and are potentially toxic to human health in high enough concentrations. In a separate study, Pollard and colleagues noted that both lakes and streams were increasing in total phosphorus (TP) concentration in the continental U.S., another indicator of eutrophication, and the most notable increases were in relatively pristine catchments.[13]
In 2018, Pollard became the first African-American woman plenary speaker at the Association for the Sciences of Limnology and Oceanography annual meeting.[10][14][15]
Awards
Embassy Science Fellow in Uruguay[16][17][18]
US EPA Science and Technology Achievement Award[19]
US EPA Gold Medal for Exceptional Service[10]
Friends of North American Lake Management Society Award[20]
