Research Briefs

  • 333 - Combining Arsenic Data Across Populations Sheds Light on Exposure Sources -- van Geen, Cardenas, Lewis
    Release Date: 09/07/2022

    By combining data across three different populations, NIEHS Superfund Research Program (SRP) researchers were able to better characterize sources of arsenic exposure that should be included in risk assessments. The study was a collaboration among the University of California (UC), Berkeley, University of New Mexico (UNM), and Columbia University SRP centers.

  • 320 - Characterizing Arsenic Exposure in Public Water Supplies and Private Wells -- Navas-Acien
    Release Date: 08/04/2021

    A recent NIEHS Superfund Research Program (SRP)-funded study revealed that while arsenic concentrations in community water systems (CWS) have decreased over time, certain populations are still vulnerable to elevated levels of arsenic.

  • 307 - Clay Layers May Worsen Arsenic Contamination -- van Geen
    Release Date: 07/08/2020

    Layers of clay are widely thought to protect groundwater aquifers from above-ground contaminants. But according to a new NIEHS Superfund Research Program (SRP) study, these clay layers may play a role in increasing groundwater arsenic contamination.
