Erin’s research focuses on chemical and biological transformations of chlorinated solvents in contaminated aquifers. Her research incorporates the use of continuous-flow columns in laboratory and field studies, with the goal of kinetically evaluating groundwater remediation strategies. The in situ research component involves the use of a novel self-contained device, the In Situ Microcosm Array (ISMA), which allows for continuous-flow microcosms to operate within a groundwater monitoring well, using groundwater and geological materials from the site.

Akash Sadaria
Graduate Student
Email:  Akash.Sadaria@asu.edu

Akash is studying the fate of neonicotinoids in a wastewater treatment facility and impacted wetland. Neonicotinoids are a class of insecticides with a common mode of action that affects central nervous system of insects, causing paralysis and death. Data suggests that neonicotinoid residues can accumulate in pollen and nectar of treated plants and may represent a potential exposure to pollinators.

Samuel Supowit
Graduate Research Associate
Email: Samuel.Supowit@asu.edu

Sam’s research focuses on the detection and quantitation of low level emerging contaminants using active sampling techniques. He uses novel sampling devices such as the IS2B active sorptive sampler, as well as conventional active sampling devices such as ISCOs to monitor the fate and transport of modern pesticides through wastewater treatment processes and engineered wetlands.
