Pyrethroid and organophosphate pesticide-associated toxicity in two coastal watersheds (California, USA).
Bryn M. Phillips,Brian S. Anderson,John W. Hunt,Katie Siegler,Jennifer P. Voorhees,Ronald S. Tjeerdema,Katie Mcneill +6 more
TL;DR: The results demonstrate that both agriculture and urban land uses are contributing toxic concentrations of these pesticides to adjacent watersheds, and regional water quality regulators are now using this information to develop management objectives.

Impacts of pesticides in a Central California estuary.
Brian S. Anderson,Bryn M. Phillips,John W. Hunt,Katie Siegler,Jennifer P. Voorhees,Kelly L. Smalling,Kathy Kuivila,Mary Hamilton,J. Ananda Ranasinghe,Ronald S. Tjeerdema +9 more
TL;DR: This study investigated pesticide impacts in the Santa Maria River estuary, which provides critical habitat to numerous aquatic, terrestrial, and avian species on the central California coast, to allow evaluation of ecosystem improvement as management initiatives to reduce pesticide runoff are implemented in this watershed.

An integrated vegetated ditch system reduces chlorpyrifos loading in agricultural runoff.
Bryn M. Phillips,Brian S. Anderson,Michael Cahn,Jessa L. Rego,Jennifer P. Voorhees,Katie Siegler,Xuyang Zhang,Robert Budd,Kean Goh,Ronald S. Tjeerdema +9 more
TL;DR: Modeling of the ditch and its components informed design alterations that are intended to eventually remove up to 100% of pesticides and sediment, and future work includes investigating the adsorption capacity of GAC, costs associated with GAC disposal, and real-world field trials to further reduce model uncertainties and confirm design optimization.

Hypersalinity Toxicity Thresholds for Nine California Ocean Plan Toxicity Test Protocols
Jennifer P. Voorhees,Bryn M. Phillips,Brian S. Anderson,Katie Siegler,Scott Katz,Lydia Jennings,Ronald S. Tjeerdema,Joanna Jensen,Maria De La Paz Carpio-Obeso +8 more
TL;DR: The effects of the aquarium’s brine effluent on topsmelt, mussels, and giant kelp were consistent with those observed in the salinity tolerance experiments, and this information will be used by regulators to establish receiving water limitations for hypersaline discharges.

Monitoring the aquatic toxicity of mosquito vector control spray pesticides to freshwater receiving waters
Bryn M. Phillips,Brian S. Anderson,Jennifer P. Voorhees,Katie Siegler,Debra L. Denton,Patti L. TenBrook,Karen Larsen,Philip Isorena,Ronald S. Tjeerdema +8 more
TL;DR: Results indicate that many of the spray pesticides used for adult mosquito control do not pose significant acute toxicity risk to invertebrates in receiving systems, and toxicity testing provided information that could lead to the inclusion of dichlorvos monitoring as a permit requirement.
