Pesticides Degrade Aquatic Habitat
  • Over 500 miles of rivers and streams and most of
    the delta in the Central Valley are officially
    listed as being impaired by agricultural
    pesticides.
  • Analysis of DPR Pesticide Monitoring Database
  • Eighty-six pesticides were detected at least
    once.
  • Pesticides were detected in nearly 8,500 samples
    (9 of all samples).
  • Pesticides were detected in 128 of the 133 (96)
    locations tested.
  • 51 of all positive detections exceeded criteria
    for aquatic health or drinking water standards

Pesticides Degrade Drinking Water
  • Pesticides have been detected in drinking water
    of 2.4 million Californians (1989-1999)
  • Banned pesticides (DBCP EDB) continue to appear
    in drinking supplies above allowable standards
  • Only 27 pesticides are regulated as drinking
    water contaminants
  • 12,000 exceedences of public health goals
    (1989-1999)
