• Characterizing Arsenic Exposure in Public Water Supplies and Private Wells
  Research Brief - August 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.
  

• Clay Layers May Worsen Arsenic Contamination
  Research Brief - July 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.
