Storm runoff and sewage treatment outflow contaminated with household pesticides
Date:2/2/2010

eir property to cut down on ants, don't realize that those same compounds end up in the American River at toxic levels."

The study found, surprisingly, that pyrethroids were present in effluent from sewage treatment plants at concentrations just high enough to be toxic to the test organisms, but well below levels found in urban runoff. Farm runoff, however, only occasionally contained pyrethroids at toxic levels, although some agricultural runoff did contain toxic levels of organophosphate insecticides.

The new study was conducted in the Sacramento-San Joaquin Delta area last winter, one of the driest in the past 10 years. As a result, water flow in the American River, which is controlled by dam releases, was at very low levels, and provided little dilution of pyrethroids entering the river in storm runoff. Preliminary tests this season, with water flow twice what it was in 2009, show that "the pyrethroid toxicity we found last year is somewhat diminished, but nevertheless still continuing," Weston said.
