Lake Ontario, the farthest downsream of the Great Lakes, suffers from water quality problems.

"Small fish living in a region of the Pacific Ocean where floating trash collects in a huge, slowly swirling bowl eat as much as 24,000 tons of plastic waste each year, scientists have found."

"The 1,300-acre, man-made [Gaillard Island off Alabama's Gulf coast] is hosting more than 50,000 birds this summer as nesting pairs gather to raise babies. That number would be considered high in any year, but it's a particularly surprising sight a year after oil from the BP spill fouled surrounding waters."

"The Pennsylvania Fish & Boat Commission said it plans to lease portions of its 43,000 acres of waterways for natural gas exploration to generate money to rebuild more than a dozen dams that are in danger of collapse."

"Green groups are cheering a proposed rule released by U.S. EPA this week that they hope will close a dangerous hazardous waste recycling loophole created in the waning days of the George W. Bush administration."

"For a decade, the people of Libby have longed for the day when they will be rid of the asbestos that turned their town into the deadliest Superfund site in America. Now they are being forced to live through the agony all over again."

"It's been a busy week for anyone following the national debates over hydraulic fracturing, or 'fracking,' the controversial method used to cut into shale rock to extract natural gas. In New Jersey, a strong bipartisan majority in both chambers of the legislature approved a bill banning fracking in the state as its neighbor to the north, New York, appeared ready to end its moratorium on the practice."
