High concentrations of uranium were discovered in U.S. community water systems (CWS), according to a study conducted by researchers at the Columbia University Mailman School of Public Health.
âWe estimated that 63.1 percent of CWS compliance monitoring records reported detectable concentrations of uranium, and that 2.1 percent of CWSs with available uranium data had 2000â11 average concentrations above the MCL [maximum contaminant levels],â based on data collected in the study published in The Lancet Planetary Health on April 1.
âDespite relatively frequent detections and relatively high concentrations compared with other metals in our study, uranium has been underappreciated in the literature as a public drinking water contaminant of concern,â said the study, titled âSociodemographic inequalities in uranium and other metals in community water systems across the USA.â…
