Addressing arsenic contamination in Allensworth, California

Allensworth is an impoverished community in California’s Central Valley that relies on drinking water contaminated with naturally high levels of arsenic, a cancer-causing toxic contaminant. . Our research group has invented a rapid and effective technology to remove arsenic from water to levels below the maximum allowed by the EPA.  This technology has been scaled up and is being field-tested in Allensworth with support from the local community and the State of California, in collaboration with UC Berkeley’s School of Public Health. Here is a TV clip produced by the news channel Al Jazeera about this effort in Fall 2022.
