Ninety percent of the diesel that spilled into Lake Nasser on Sunday has already evaporated due to high temperatures in Aswan, the Environment Ministry claimed on Thursday.
The rest of the spill was mopped up by the Armed Forces with huge sponges, the ministry alleged.
Preliminary investigations suggested that the spillage came from a leaky ship stationed at the port of the High Aswan Dam.
On Thursday Environment Minister Khaled Fahmy ordered the formation of a field committee to perform a full scan of the High Dam port area to ensure that no contamination occurred from the spill.
