EES student publishes research
EES doctoral student Leah Jackson recently published results from her work on monitoring groundwater contamination beneath Ann Arbor, Michigan in the Hydrogeology Journal. She is studying bioremediation efforts at the Gelman Site where a plume of 1,4-dioxane has contaminated local drinking water wells, forcing the city to draw water instead from a nearby reservoir. Her analysis of the available date from a network of groundwater monitoring wells suggests that contaminant migration has appeared to slow or stop over the last 12 years. She and advisor Dr. Lawrence Lemke have mathematically examined the potential for natural processes (as opposed to ongoing engineered remediation) to explain this behavior. They have demonstrated that there is a very real possibility that natural processes, such as the contaminant clinging to sediments or being eaten by microbes, are at play here.
