Asunto: Storm runoff and sewage treatment outflow contaminated with household pesticides
| Pyrethroid pesticides were supposed to be a benign replacement for organophosphate use around the home, but UC Berkeley studies show that these insecticdes are showing up at toxic levels in storm runoff and even in the effluent from sewage treatment plants.
