Three months after residents began waging a campaign on Instagram saying they’re concerned herbicides are poisoning local creeks, Orange County officials announced they are halting spraying of the chemicals, for now, in waterways throughout the county. Starting in February, posts by the community group Creek Team OC sparked an outpouring of concern among residents. They posted images of workers spraying chemicals and used artificial intelligence to make illustrations featuring surfers under the slogan “Endless Herbicides.” In March, county Supervisor Katrina Foley told residents the county would halt spraying of herbicides in two creeks near Doheny State Beach.
