Dr. Afrachanna Butler, a research physical scientist with ERDC's Environmental Laboratory (EL), and Kortland Almore, an EL intern from Alcorn State University, water switchgrass in one of EL’s greenhouses in Vicksburg, Mississippi. Both ERDC-EL and ERDC’s Cold Regions Research and Engineering Laboratory are experimenting on the phytostabilization potential and biomonitoring of heavy metals, specifically selenium and arsenic that come from contaminated soil and groundwater at coal combustion residual (CCRs) storage sites.
