At 8.55am this morning, a local resident telephoned the offices of the Formentera Council to report an oil slick on Estany des Peix. Two personnel of the CiF Office of Environment visited the pond and, confirming the presence of a minor spill, dialled 112, an agency of the Govern's department of emergency services, whereupon the bureau's plan for oil spills, the Cambal plan, was activated.

In the morning the Guardia Civil made passes over the area in the brigade's helicopter to make sure no new oil infused the water. The head of ses Salines preserve visited the scene to assess the situation as the Council employees used a boat from the administration's fleet to assist coastal authority officers search for the source of the spill, still undetermined at the time of writing.

A TRAGSA crew brought in by the coastal authority was tasked with commencing cleanup operations in the area. The team will begin by mapping out the affected portion of the lake. Soiled sand will be cleaned mechanically and any affected rocks will be treated with sawdust or absorbent blankets.
