The lethal effects of urban runoff that kills some salmon and their prey can be reversed by filtering the water through a common soil mix, according to new research by state and federal scientists.

When it rains or people wash their cars, the water that runs over pavement picks up toxic chemicals such as oils, heavy metals and residue from car emissions. This can go straight into our waterways.
