Environmental Effects – Water Contamination

Imidacloprid has a high potential of leaching into groundwater. Although
its persistence varies from the shortest half life of 107 days to
concentrations which didn’t begin to decline until over a year after
use,[13] there is little question about imidacloprid’s tremendous ability
to move through soil.[14] Compared with 11 other popular pesticides
Imidacloprid moved more quickly through soil than any of the other
pesticides tested.[15] The other 10 pesticides tested included diazinon,
chlorpyrifos and diuron which are widespread water contaminants.[16] It is
classified by the EPA in category I as having the highest leaching
potential.
