In Orange County, residents are speaking up about the use of herbicides in local waterways. Many believe these chemicals could harm the environment, and their concerns have led to a town hall meeting scheduled for Monday night.
Brent Linas, a tech sales director and father from San Juan Capistrano, started the Instagram account Creek Team OC after noticing alarming changes in the San Juan and Trabuco creeks. The vibrant green reeds turned brown, and the usual chirping birds vanished. He felt ignored by local officials, prompting him and his neighbors to use social media to make their voices heard. “Spraying these creeks dead is unacceptable,” he stated.
In just three weeks, the account gained over 4,600 followers. Residents have been asking for details about chemicals used in the waterways, such as glyphosate, triclopyr, and imazapyr. They’ve been documenting the spraying and even creating art with AI to draw attention to their cause.
Brent often visits Doheny State Beach with his kids, and many surfers there share his concerns. “It’s bringing a lot of anger within our community,” he said.
Orange County Public Works officials defend their herbicide use, stating it’s essential for flood protection. Dave Ahern from the agency emphasized that treatments are applied carefully and according to regulations. Still, public sentiment is shifting. County Supervisor Katrina Foley expressed her opposition to herbicides in waterways and aims to find safer methods.
Recent data shows that chemical use, particularly glyphosate, has been under scrutiny. Glyphosate is the main ingredient in Roundup and faces numerous legal challenges over health risks that may include cancer. Critics argue that Orange County should follow the example set by nearby San Diego, which manages vegetation without heavy reliance on chemicals.
Documents obtained by local activists revealed that the county planned to spray herbicides across more than 2,000 acres this year. The community is not only demanding transparency but also pushing for less toxic alternatives for vegetation control. Some ideas being considered are manual weeding or even using goats to maintain natural growth.
In this heated debate, two perspectives are emerging: those who view the creeks as vital ecosystems deserving protection and officials who see them primarily as flood management channels. As waterways become a contentious issue, the community’s outcry, combined with evolving regulations, may lead to significant changes in how local authorities approach vegetation management in the future.
