    • Pesticide detections in streams throughout the foothills of the Sierra Nevada range using passive samplers from 2017 to 2019

    Metadata Updated: October 30, 2025

    This dataset was produced from analyzing Affinisep SDB-RPS, Affinisep HLB, and Restek Resprep C18 disks that were deployed with the use of Chemcatcher® passive sampling devices. Silicone bands were also deployed and used for exploring economical methods of sampling for pesticides in surface water. Sampling assemblies were deployed in streams throughout the foothills of the Sierra Nevada range and California's northern Central Valley from 2017 to 2019. Samples were extracted in situ then eluted and concentrated at the Organic Chemistry Research Laboratory in Sacramento, CA. Samples from silicone bands were extracted via agitation in appropriate solvents. Samples were analyzed for a suite of 155 pesticides and degradates with gas chromatography-tandem mass spectrometry and liquid chromatography-tandem mass spectrometry. There were a total of 21 different pesticides detected throughout this study.
