Pesticide Water Quality Criteria Development

The Central Coast Water Board contracted with the University of California Davis (UC Davis) to derive water quality criteria for neonicotinoid insecticides. Under previous contracts with the Central Valley Water Board, UC Davis developed a methodology to derive water quality criteria for pesticides and used this methodology to derive water quality criteria for other pesticides.

The final reports for all pesticide criteria derived using the UC Davis methodology are available on the UC Davis website: https://ucdaviswatercriteria.wordpress.com/pesticide-reports/
