Close to Tazarka, in the governorate of Nabeul, Daroufa is a reputedly idyllic, pristine beach. This summer, Daroufa beach-goers, alarmed by the nauseating odor that sometimes emanates from the sea, gave voice to their concerns on social media. And yet nothing appeared to be out of the ordinary, says Rabeb, a Daroufa regular. The beach is located near the industrial zone called « Mazrâa », and the Sabkha, or wetlands. Not far away, at the beach in El Maâmoura, disenchanted locals film a stream of blackish water that is running into the sea.
