Southwestern correctional facilities’ drinking water puts inmate health at risk

The first nationwide analysis of drinking water quality in United States correctional facilities found average arsenic concentrations in drinking water in Southwestern United States correctional facilities were twice as high as average arsenic concentrations in other Southwest community drinking water systems. More than a quarter of correctional facilities in the Southwest reported average arsenic levels exceeding the U.S. Environmental Protection Agency 10 μg/L maximum contaminant level.
