An Environment Ministry official told Army Radio that the spill was one of the worst environmental accidents in Israel’s history.
The breach happened by accident during maintenance work on Wednesday night on the Eilat-Ashkelon pipeline, some 12 miles north of the Red Sea resort of Eilat.
Doron Nissim of Israel’s Nature and Parks Authority said the black slick had run and pooled in ravines, but appeared to have spared the 4,250-acre Evrona reserve’s rare deer and douma palms.
In the absence of heavy rainfall, there was little chance of the oil sluicing to Eilat and endangering Red Sea marine life, but there was “no doubt that insects and other crawling animals have been harmed,” he said.
Three people were taken to the hospital after inhaling oil fumes, police said.
The leak was stopped before the torrent of oil could cross the nearby Jordanian border, Israel’s Environment Ministry said. Civil defense officials in Amman said several Jordanians had gone to the hospital as a precaution after smelling the fumes, but had not required treatment.
Environment Ministry official Guy Samet estimated the spillage at millions of gallons, telling Israel Radio: “Rehabilitation will take months, if not years.”
Nissim said pools of oil would probably be drained with suction equipment, and contaminated earth might also be removed.
The main road leading to Eilat from central Israel was closed intermittently.
