Narrator: This is Science Today. New research reveals that Latino communities in California's San Joaquin Valley are disproportionately exposed to high levels of nitrate in their drinking water. Researcher Carolina Balazs of the University of California, Berkeley, says their findings could have implications for water use issues in other marginalized communities, as well.
Balazs: In terms of broadly thinking about drinking water contamination, race and class, this study is really important because there are other regions in the U.S. that face similar problems.
Narrator: Balazs explains that many low-income African-American communities in the South and unincorporated border communities in the Southwest face similar water contamination and infrastructure issues.
Balazs: Asking whether there's this social disparity based on race is important so that we can understand why some of these health disparities that exist among different demographic groups. Not only to understand the health impact, but then to understand, how do we solve this problem?
