Pesticide Water Quality Criteria Development

UC Davis Imidacloprid Water Quality Criteria

The Central Coast Water Board contracted with the University of California Davis (UC Davis) to derive water quality criteria for the insecticide imidacloprid. UC Davis developed the methodology used to derive water quality criteria for pesticides under a previous contract managed by the Central Valley Water Board. The UC Davis methodology has been used to derive the criteria for fourteen other pesticides. Links to the methodology and other pesticide criteria derivation reports are available at the Central Valley Water Board website.

• Draft Imidacloprid Criteria Technical Report – This draft technical report describes the water quality criteria derived for the insecticide imidacloprid.
• Notice of Opportunity for Public Comment - The Central Coast Water Board is seeking comments on the technical aspects of the UC Davis Draft Imidacloprid Criteria Technical Report. Comment letters must be received by 12:00 noon on February 25, 2019.
