" The Abbanoa systems have worked properly ." This is what the company wrote in a press release after the controversy over the heavy rains that hit Santa Teresa Gallura and led, since August 20, to the bathing ban (later revoked) established by the mayor Nadia Matta in Rena Bianca, La Marmorata, Porto Quadro and Cala Sambuco.

"It is not surprising that some samples of coastal waters taken after the exceptional rainfall of the past few days may present non-standard temporaries," the statement continues. "Even neglecting to consider that Abbanoa has no discharges in the coastal areas affected by the restriction, we believe that the possible sources of contamination should be sought elsewhere " and "communications to the control bodies, about possible alarms, fall within the normal and transparent communication duties to which Abbanoa is subject in the case of exceptional events."
