Caffeinated Mayflies

Water in the Tennessee River isn’t going to give you the wake-up jolt that a cup of coffee does.

But it has enough caffeine to do that – and more – for the tiny wildlife living in and around the Tennessee River, according to researchers who found the presence of caffeine and a number of other drugs in the local water supply.

Caffeine exists in a high-enough concentration to force-feed a typical baby mayfly the equivalent of 26.6 cups of coffee a day, according to Sean Richards, associate professor of biological and environmental sciences at the University of Tennessee at Chattanooga. Caffeine was found in more than93 percent of about 160 test samples of river water.
