Brain-damaging lead found in tap water in hundreds of homes tested across Chicago, results show

A Tribune analysis of the results shows lead was found in water drawn from nearly 70 percent of the 2,797 homes tested during the past two years. Tap water in 3 of every 10 homes sampled had lead concentrations above 5 parts per billion, the maximum allowed in bottled water by the U.S. Food and Drug Administration...

...Lead is unsafe to consume at any level, according to the EPA and the U.S. Centers for Disease Control and Prevention. Ingesting tiny concentrations can permanently damage the developing brains of children and contribute to heart disease, kidney failure and other health problems later in life. A peer-reviewed study published last month in The Lancet, a London-based medical journal, estimated that more than 400,000 deaths a year in the U.S. are linked to lead exposure — or 18 percent of all deaths.
There is no federal standard for the amount of lead found in tap water at individual homes, but studies have reported harmful effects when concentrations exceed the FDA’s standard for bottled water. In a recent peer-reviewed study, EPA scientists cautioned that when children under age 7 drink water containing more than 5 ppb of lead on average, the amount of the metal in their blood can rise above CDC health guidelines...
...“Chicago’s testing blows out of the water one of the foundations of (federal regulations), namely that current lead-in-water monitoring requirements yield reliable information about the extent and severity of contamination across a service area,” Lambrinidou said...
