Environmental Spill Disaster Devastates Tennessee;
48 Times the Size of Exxon Valdez
By Matthew McDermott, TreeHugger. Posted December 25, 2008.
Approximately 500 million gallons of coal ash sludge has broken through a holding pond at a coal-fired plane.
An environmental disaster of epic proportions has occurred in Tennessee. Monday night, 2.6 million cubic yards (the equivalent of 525.2 million gallons, 48 times more than the Exxon Valdez spill by volume) of coal ash sludge broke through a dike of a 40-acre holding pond at TVA's Kingston coal-fired power plant covering 400 acres up to six feet deep, damaging 12 homes and wrecking a train.
According to the EPA the cleanup will take at least several weeks, but could take years. Officials also said that the magnitude of this spill is such that the entire area could be declared a federal superfund site.
Toxic Sludge Got Into Tributary of Chattanooga Water Supply
Apart from the immediate physical damage, the issue is what toxic substances are in that sludge: Mercury, arsenic, lead, beryllium, cadmium. Though officials said the amounts of these poisons in the sludge could not be determined on Monday, they could (at the mild end) irritate skin or trigger allergies or (longer term) cause cancer or neurological problems.

“What toxic substances are in that sludge: Mercury, arsenic, lead, beryllium, cadmium.” as reported by Matthew McDermott (see article below). All of these substances are or have been pigment matter used in paints and other art materials. For more details, click here.
Lead, Mercury, Cadmium, Chromium, Barium and Arsenic
Lead, mercury, cadmium, and chromium were commonly used in paint as pigments and preservatives and are now found in paint on older buildings. Arsenic has used as a pigment, a wood preservative and as an anti-fouling ingredient. Barium has been used as a pigment and a corrosion inhibitor.
Lead in paints has primarily been lead carbonate (white lead), The amount of lead in pigment may be very high, up to 40% (or 400, 000 parts per million) of dry old paint (prior to the 1960s) is composed of white lead. It was also used in colored paints.
Lead chromate (chrome yellow) was used in colored paint in 5 to 7% concentrations (or 50,000 to 70,000 parts per million).
Lead tetroxide (red lead) is also a component of paints.
