But most treatments do not remove all drug residue. A sex hormone was detected in San Francisco's drinking water. Read more.

WATCH: The Secret Buzz Only Bumblebees Know To Unlock Our Favorite Crops, NPR

In the summertime, the air is thick with the low humming of bees delivering pollen from one flower to the next. If you listen closely, a louder buzz may catch your ear.
