A pond, dry in the summer , like the many that characterize the back shore of the beaches of Golfo Aranci, has been full of cloudy, purple-colored water and an unhealthy smell for over a week.

The Maremosso citizens' committee has reported the situation of the pond next to Sos Aranzos beach .

"We cannot ignore what appears to be a spill of sewage or other presumably polluting substances: the water appears to be flowing directly into the sea on a very busy beach," the committee says.

And they add: "We ask the competent authorities to intervene as soon as possible to identify the nature of this anomaly, safeguard the health of citizens and protect the marine environment."
