Caffeine flushed into Pacific Ocean stresses marine life–CBC

So my question is: Is Caffeine ‘legacy’ as well as modern? Does it have a half life? Is this the caffeine that was dumped by our fathers in the 30s into the Sound after drinking coffee? Or is it modern?

Caffeine has become a significant pollutant in the ocean off the U.S. Pacific Northwest, according to a university researcher. Elise Granek, a marine ecologist at Portland State University in Oregon, sampled waters up and down the Oregon coast and found measurable levels of caffeine…Granek, who did all her initial research in the waters off Oregon, said she’s curious about caffeine levels in the Strait of Juan de Fuca between southern Vancouver Island and the Washington coast. That’s where Victoria pumps untreated sewage effluent directly into its coastal waters, and won’t have a sewage treatment facility in place until 2018.
