Down by the rushing stream, banks of wild yellow irises shimmered in the twilight, and up in the vaulted corridor that the tracks cut through the trees, the mild June air was filled with twinkling green fireflies.
In their university-funded study, Dr. Brodin and his colleagues first tested wild European perch caught from a midsize stream in Sweden called the River Fyris and found that levels of the drug in fish tissue were more than six times the level commonly detected in the water.
At long last, we reached the Wild River, promptly disrobed and sat in the low but rushing stream, letting the cool water wash over us as we filled and sterilized our bottles.
