Groundwater Modeling

Columbia Northern Plains Superfund Research Program Project 1

High-resolution Models of Groundwater Metal Exposure

PI: Steven Chillrud, PhD

There is a lack of groundwater data in Northern Plains Native American tribal communities despite groundwater being the most likely source of exposure contributing to high urinary arsenic and uranium levels in these communities. Project 1 will merge new measurements of drinking water quality with existing spatial datasets to develop process-based models that predict contaminant concentrations at the household scale across Northern Plains tribal sites. The results, together with evaluations of temporal changes in drinking water concentrations from prior policy interventions and development of drinking water exposure profiles for the study cohort, will enable the development and establishment of effective interventions to reduce these potentially hazardous exposures to contaminated drinking water in the Northern Plains and beyond.
