High caffeine levels in the waters off the Oregon coast are likely the result of pollution from human waste, scientists say. After testing water samples from 14 spots, researchers from Portland State University and Washington State University found high levels of caffeine at two sites far from large population centers, while discovering low levels of caffeine near cities and wastewater treatment plants. While far below deadly levels, the caffeine could be affecting marine life in unknown ways, the study's authors say.
