"U.S. EPA has found 104 chemicals that might require regulations to keep them out of tap water -- the longest list of potential contaminants ever compiled by the agency."

"Runoff from all but the largest farms is essentially unregulated by many of the federal laws intended to prevent pollution and protect drinking water sources."

"The Obama administration called Thursday for a comprehensive national system for regulating the use of federal waters along the nation’s marine and Great Lakes shores, now administered by a hodgepodge of federal, state or other agencies with often-conflicting goals."

"Many urban streams have become salty enough to harm aquatic life, largely because of salt used for deicing roads in the winter, according to a new government study released Wednesday."

"Cleanup of the most polluted sites in the Great Lakes is moving so slowly it will take 77 more years to finish the job at the existing pace, according to a federal report."

"The federal government said Thursday that it would seek an unprecedented role as the environmental police of the Chesapeake Bay -- enforcing new rules on farmers and keeping a closer eye on state-level bureaucrats -- in an effort to halt the estuary's long decline."

"Caves are home to some of the planet's most unusual creatures and important drinking water supplies. Now these underground resources are being polluted by surface activities, ranging from sewage spills to old factories. Experts call the problem 'extensive and serious.' Mammoth Cave National Park in Kentucky, Crevice Cave in Missouri and Whispering Canyon Cave in Alaska are examples. 'People need to be aware that there’s a subterranean ecosystem and that what happens on the surface impacts these unique ecosystems in a very real way,' said David Culver, a biologist at American University."

"Crops are wilting in the countryside, and the capital's water shortage has turned dire as Mexico grapples with its worst drought in more than half a century."

"Scientists who returned to the Bay Area this week after an expedition to the "Great Pacific Garbage Patch" brought piles of plastic debris they pulled out of the ocean — soda bottles, cracked patio chairs, Styrofoam chunks, old toys, discarded fishing floats and tangled nets."

"The Environmental Protection Agency should move immediately to adopt enforceable limits on the release of nutrient pollutants -- such as fertilizer and sewage -- into rivers and streams to halt the creation of dangerously low oxygen areas in water bodies, and the dead zone in the Gulf of Mexico should be one of its first targets, the agency's Office of Inspector General said in a report made public today."
