Urban Run-off Research

Eleven pest control chemicals, including products no longer commercially available, were found virtually year-round in storm drain water samples from eight selected California neighborhoods. The main ingredients of lawn and garden fertilizers were also found in the water samples at all sites.

A collaboration of researchers, led by Orange County Water Resources/Water Quality Advisor Darren Haver and University of California Cooperative Extension Specialist Loren Oki, have been conducting a multi-year study to characterize the run-off from single-family home neighborhoods in Northern and Southern California. Education provided to homeowners in the test neighborhoods is expected to reduce both the amount of run-off water and potentially harmful contents. Computer models of flows and loads will aid future urban planning.
