A new study shows that stormwater runoff from urban roadways is so toxic to coho salmon that it can kill adult fish in as little as 2½ hours. But the research by Seattle scientists also points to a relatively easy fix: Filtration through a simple, soil-based system. “It’s basically … letting the Earth do what it does so well, what it has done for eons: cleaning things up,” said Julann Spromberg, a toxicologist for NOAA and co-author of the study.
