"Perhaps the last thing the Navy is looking for at the moment is a tangle with environmentalists. But that is exactly what it has -- over a proposed $100 million naval warfare training range off the northern Atlantic coast of Florida."

"Two of Florida's top politicians are pushing state and federal regulators to approve a taxpayer-funded breakwater that would slow down, but not stop, erosion threatening expensive Palm Beach County condos. But biologists fear the breakwater will block sea turtles from one of the most important nesting beaches in the state."

"People in North Texas worry about tornadoes, not earthquakes. That's not the case in the small town of Cleburne, just south of Fort Worth. They've had six quakes so far this month. Cleburne happens to sit on a huge, recently discovered natural gas deposit called Barnett Shale. There's been a lot of drilling, and some people wonder if that has triggered the earthquakes."

Engineering projects hope to save Louisiana's shrinking coastal wetlands by diverting sediment from the Mississippi River -- but a new study says there is not enough mud in the Mississippi to do the job.

Environmentalists say Florida officials are thwarting a 2-year-old law banning the spreading of sewage sludge on the Everglades.

The landfilling of 3.9 million tons of coal ash from a spill at TVA's Kingston Fossil Plant may or may not be a boon to one of Alabama's poorest counties.

"The earthen dikes supporting a huge coal ash landfill at a Tennessee power plant were 'on the verge of failure' long before they collapsed and sent tons of toxic muck into a river and lakeside community, an engineering consultant said Thursday."

Two brothers are busting levees to return the Ouachita National Wildlife Refuge to its primeval condition.

If the Army Corps of Engineers and private companies used all the mud they dredge from wetlands and waterway to rebuild Louisiana coastal marshes, it would be a boon for coastal restoration.

A National Research Council report says it may be impossible to know whether contaminated drinking water at the Camp Lejeune Marine base caused birth defects and illness among people seeking $33.9 billion in claims.

Abandoned gas stations dot some Florida highways. Economic conditions bear part of the blame. But operators' inability to pay for replacement of old, leaky tanks ironically may be causing more old tanks to be left in the ground.

"The Supreme Court refused Monday to hear a Marine's lawsuit blaming the government's dumping of toxic chemicals at Camp Lejeune in North Carolina for his son's illnesses."

"Just days before Christmas last year, an environmental disaster one hundred times the size of the Exxon Valdez (yes, you read that right) unfolded on a riverbank in eastern Tennessee. A wave of poisonous sludge buried a town…along with the myth of clean coal."

"Legislation allowing more selenium to be released into Tennessee streams fell one vote short of passage Wednesday after lawmakers were told approval would mean poisoning the state's waters to help coal company win a lawsuit attacking its pollution."
