I wonder where the caffeine comes from

Right down the street from the home of Starbucks you have caffeine in it's drinking water. Who would have thunk it?

Researchers find caffeine in waters off Oregon

(CNN) -- A study has found elevated levels of caffeine in the Pacific waters off the Oregon coast, but it doesn't appear that the region's many cafes and coffeehouses are to blame.

Right!

Researchers from Portland State University and Washington State University, Vancouver, looked at caffeine pollution off the coast as part of a broader study of contaminants in the water. Their findings are published in the July 2012 Marine Pollution Bulletin.

After taking samples from 21 spots along the coast, researchers expected to find the most caffeine pollution in areas near wastewater treatment plants, large population centers or rivers and streams emptying into the ocean, said Elise Granek, assistant professor of Environmental Science and Management at Portland State. She conducted the study with her former graduate student, Zoe Rodriguez del Rey, and Steve Sylvester of Washington State.

Instead, they found high caffeine levels near Carl Washburne State Park and Cape Lookout, two areas not near the potential pollution sources, and low levels of caffeine near large population centers such as Astoria, Warrenton and Coos Bay.

They also found high levels of caffeine after a late-season storm that triggered sewer overflows...

I won't go further on the sewer point. You know you will come to a conclusion yourself!

Let me refill my coffee cup and look more on the computer.
