Water in all fountains at Chicago's public parks will be tested for lead, according to the Chicago Park District.
The park district has already tested 158 fountains, and "two tested above the EPA's action level and have been turned off while we investigate the cause and determine the appropriate corrective actions," reads a statement from the district.
"The Chicago Park District will test all water fountains, both indoor and outdoor, across the city," the statement adds. "The results of this testing will be posted online."
According to WBEZ, there are 60 Chicago parks with fountains that have tested positive for low levels of lead.
Drinking water is also being tested for lead in Chicago's public schools across the district.
