From the Associated press "Monday's reservoir break at an alumina plant dumped up to 700,000 cubic meters (184 million gallons) of sludge onto three villages, government officials said, not much less in a few hours than the 200 million gallons the blown-out BP oil well gushed into the Gulf of Mexico over several months. The red sludge devastated creeks and rivers near the spill site and entered the Danube on Thursday, moving downstream toward Croatia, Serbia and Romania. Monitors were taking samples every few hours Friday to measure damage from the spill but the sheer volume of water in the mighty Danube appeared to be blunting the red sludge's immediate impact.
Test results released by Hungary's disaster agency show the pH level of the water where the slurry entered the Danube was under 9 — well below the 13.5 measured earlier in local waterways near the site of the catastrophe. That is diluted enough to prevent any biological damage, Interior Minister Sandor Pinter said.
Despite the apparent good news, the risk of pervasive and lasting environmental damage remained at the site of the spill, with Greenpeace presenting laboratory tests that it said showed high concentrations of heavy metals in the sludge."
