AP: BP Oil Not Degrading on Gulf Floor, Study Says

BIRMINGHAM, Ala. (AP) — Tar balls washed onto Gulf of Mexico beaches by Tropical Storm Lee earlier this month show that oil left over from last year's BP spill isn't breaking down as quickly as some scientists thought it would, university researchers said Tuesday.

Auburn University experts who studied tar samples at the request of coastal leaders said the latest wave of gooey orbs and chunks appeared relatively fresh, smelled strongly and were hardly changed chemically from the weathered oil that collected on Gulf beaches during the spill.

The study concluded that mats of oil — not weathered tar, which is harder and contains fewer hydrocarbons — are still submerged on the seabed and could pose a long-term risk to coastal ecosystems.

When Capitalism Converges With Resilience

It is hard to argue against that fact that the U.S. and even "Communist" China, for that matter, have great influence in global markets and on health and human security -- for their own people as well as human populations world-wide. The power of capital within global, regional, national, and local markets has been transforming the world since the growth of the industrial revolution, which has only accelerated since the broad introduction of global communication and computing in the 20th century. That said, there has been growing criticism of the destructive nature of market fundamentalism and laissez faire economics in the face of a growing awareness of ecosystem carrying capacities, and the problems inherent in growth economies in decline.  So what happens when capitalists become aware of the destructive nature of growth economies, where populations are exceeding the carrying capacities of ecosystems and mass consumption economies begin to collapse?

Deepwater Trouble on the Horizon: Oil Discovered Floating Near Source of Gulf of Mexico Spill (Video & Photos)

MOBILE, Alabama -- Oil is once again fouling the Gulf of Mexico around the Deepwater Horizon well, which was capped a little over a year ago.

Tuesday afternoon, hundreds of small, circular patches of oily sheen dotted the surface within a mile of the wellhead. With just a bare sheen present over about a quarter-mile, the scene was a far cry from the massive slick that covered the Gulf last summer.

Floating in a boat near the well site, Press-Register reporters watched blobs of oil rise to the surface and bloom into iridescent yellow patches. Those patches quickly expanded into rainbow sheens 4 to 5 feet across.

Each expanding bloom released a pronounced and pungent petroleum smell. Most of the oil was located in a patch about 50 yards wide and a quarter of a mile long.

As Heat Soars, New Yorkers Warned to Stay Out of Rivers

msnbc.com - July 22, 2011

A warning by the Hudson River near West 90th Street on Thursday. Millions of gallons of untreated waste spilled into the river - Monika Graff for The New York Times

New Yorkers have been warned to stay out of the Hudson and Harlem Rivers on one of the hottest weekends of the year after millions of gallons of untreated sewage discharged from Manhattan into the waterways because of a four-alarm fire that shut down one of the city’s largest sewage treatment plants.

The city's drinking water has not been impacted, officials said, but people have been cautioned not to swim or kayak on the waterways through at least Monday.

The New York City health department also declared large parts of the East River and the Kill Van Kull unfit for swimming through the weekend.

Local authorities did not expect any beaches in the area to be closed because of the spill.

EPA Fracking Study To Focus On 5 States, But Not Wyoming

The Huffington Post - June 26, 2011

by ProPublica's Abrahm Lustgarten

The Environmental Protection Agency will focus its national study of hydraulic fracturing on seven areas in five states, but will exclude the two Wyoming gas fields where agency researchers have already collected some of the most in-depth data on drilling's environmental impacts.

The study – which was announced last March, without specifics on research sites – will investigate alleged water contamination from drilling in five areas in Texas, Colorado, North Dakota and Pennsylvania. It also will encompass cradle-to-grave research projects in Pennsylvania and Louisiana, where the agency will track drilling's effects on water quality from before the drill bit hits the ground to after hydraulic fracturing has been performed.
