Pesticides and Water Quality

How Pesticides Move to Other Locations

When you apply a pesticide, it may drift in the air or be washed into a storm drain by irrigation or rain.

None
  • During application, airborne particles can drift and land on surface water, or rain can wash particles from the air.
  • For several days after pesticide application, irrigation and rain may wash pesticide residues into storm drains.
  • Chemicals may also enter storm drains directly or indirectly through spills, illegal dumping, or rinse water from product containers.
  • Stormwater runoff empties into creeks and creeks empty into rivers.
