Environmental justice and inequalities in public drinking water contaminant exposures

We are developing nationwide public drinking water contaminant exposure estimates. Our objective is to evaluate racial/ethnic and socioeconomic inequalities in public drinking water contaminant exposures and evaluate the causal association between these exposures and inequalities in related adverse health outcomes. Findings from these projects can inform public health interventions and regulatory action with the ultimate goal of reducing inequalities in both drinking water contaminant exposures and adverse health outcomes across racial/ethnic and socioeconomic subgroups.

Drinking water quality in correctional facilities

We published the first study of drinking water quality in correctional facilities across the US. Our work found elevated drinking water arsenic exposure for incarcerated populations in the Southwestern US (2006-2011). Weโ€™re currently expanding this work to evaluate additional regulated drinking water contaminants.

Mercury exposure assessment: a community-directed research project

We are working with community-based collaborators in the Northern Plains to design and implement a pilot study to characterize mercury exposure in tribal communities using both biomonitoring and environmental monitoring. A key component of this project is the inclusion of local high school students in field work/data collection, data analysis, and results dissemination. We mentor local students through high school science fair projects related to population- and community-level metal exposure assessment and plan to expand this collaboration even further beyond the aims of this specific project.
