"Canadian mining giant Teck Resources Ltd. has admitted in a U.S. court that effluent from its smelter in southeast British Columbia has polluted the Columbia River in Washington for more than a century."

"Aging boomers pop more pills to keep fit. Farmers feed more antibiotics and hormones to fatten livestock. Adults and children use exotic shampoos and conditioners to make their hair shiny.

"Canada and the United States have updated a decades-old agreement to protect the Great Lakes, adding new commitments to protect aquatic habitats, curb invasive species and help coastal communities adapt to climate change."

"Long-awaited dredging will begin this month in Waukegan Harbor to remove soil contaminated with hazardous substances at a Superfund site once described as the 'world's worst PCB mess,' officials announced Thursday at the Waukegan Yacht Club."

"The Obama Administration [Thursday] gave Shell approval to prepare for oil drilling in environmentally fragile Chukchi Sea off Alaska although a critical oil spill containment vessel has not been certified. Shell will be permitted to start 'certain limited preparatory activities' for drilling off Alaska’s northwest coast, Interior Secretary Ken Salazar told reporters."
