"Detroit Oil Spill Remains a Mystery 10 Years Later"

"DETROIT -- The first call came in from one of the control towers at drawbridges along the Rouge River. It was April 10, 2002, and by the time the reports of large amounts of oil in the water reached U.S. Environmental Protection Agency officials, the spill likely had been under way for at least a day. By the time the contaminated flows had stopped, as many as 250,000 gallons of oil had spread over three miles of the Rouge, into the Detroit River and been carried as far south as Lake Erie."

"Plastic Pollution in Ocean Likely Underestimated, Researchers Say"

Residents Fear Storage of Chemical Waste in Landfill Over Aquifer

"CLINTON, Ill. -- Fly over Clinton and the 266-acre landfill south of town doesn't look much different than 44 other landfills in Illinois.

But beneath its surface of inoffensive trash, the kind you put at the curb each week, are 4 trillion gallons of water used every day for public use, industry and irrigation in 15 Central Illinois counties.

And if ever the two shall meet, there could be trouble for the 750,000 people who rely on the Mahomet Aquifer, especially if Area Disposal's landfill starts accepting PCBs, a certain type of hazardous waste.

EPA Frustrates Groups with Delay on Coal Ash Hazwaste Ruling

"LOUISVILLE, Ky. -- Black dust from the giant coal ash heap across the street from Kathy Little's Louisville home swirls in the wind, coating her windows, her car, and blows indoors to settle on the furniture. The ash blanketing Little's property is a byproduct of a nearby coal-burning power plant. Since it's full of fine particles of arsenic, chromium and other metals, the U.S. Environmental Protection Agency is considering classifying the ash as a hazardous material."
