At Gompers Park Lagoon on the city’s Northwest Side, as an example, Cooper said there are three stand-alone water fountains that dot a paved, circular path that’s about a quarter-mile long. Currently, one of those three fountains falls in the group of 500 that do not have a problem with lead in the water. As of this weekend, it was being flushed; the two other fountains were turned off — and by Monday, had been removed.
