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.

• Water Quality Criteria Report for Imidacloprid – This final project report describes the acute and chronic water quality criteria derived by UC Davis for the insecticide imidacloprid
• Responses to Public Comments and Peer Reviews – This document contains the public comments and peer review comments of the Draft Imidacloprid Criteria Technical Report as well as the UC Davis responses to those comments.
