High lead levels have been found in the drinking water at 11 additional Chicago public schools, according to new reports.
After a pilot program found high levels of lead in three water fountains at Tanner Elementary on the city's South Side last month, Chicago Public Schools officials announced plans to test the water at every school in the district.
The district is currently testing water at schools built prior to 1986 as those sites are more likely to have lead service lines. The district is also testing the water at schools with prekindergarten programs. Water in Chicago schools had not been previously tested for the heavy metal before the discovery at Tanner Elementary.
