Pipeline Ruptured in Arkansas, Major Oil Spill

A leak from the Pegasus pipeline was discovered near Mayflower, Arkansas on Friday, leading to an estimated spill of over 10,000 barrels of Canadian Dilbit. Reports state that the pipeline was carrying Wabasca Heavy crude from western Canada when it ruptured. Wabasca Heavy is a type of diluted bitumen (a type of crude oil that is heavier than most conventional crude oil) from Alberta's tar sands region.

Pharmaceuticals in Streams

Pharmaceuticals commonly found in the environment are found in streams, with unknown impacts on aquatic life and water quality. So reports a new Ecological Applications paper, which highlights the ecological cost of pharmaceutical waste and the need for more research into environmental impacts. Pharmaceuticals, or prescription and over-the-counter medications made for human use or veterinary or agribusiness purposes, are found often in the environment. Antibiotics,vitamins, supplements, and sexual enhancement drugs are contained in this group. These products typically enter the environment when passed through the body and then entering into the ground or sewer lines, or when disposed of in the trash, septic tank, or sewage system.

While illegal cattle ranching continues to be a major threat, oil interests have been hard to keep at bay.
