For days, Venetians have wondered what caused a swath of their city’s famous Grand Canal to turn bright green.
On Monday, the authorities had an answer: Test samples of the water confirmed that the canal’s bright new hue was caused by fluorescein, a chemical often used to find leaks during underwater construction.
Now, Italian officials are investigating how the chemical got into the canal.
Still, officials do not know who or what was behind the color.
Luca Zaia, the president of the Veneto region, said on Facebook on Monday that the possibility of copycats was “worrying.”
