To Austin City Council, Mayor Kirk Watson and Austin Parks and Recreation,

Cancer rates are rising at alarming levels—and yet, every day at Barton Springs, people are spraying chemical sunscreens into the air without a second thought. These products contain known toxins and carcinogens that linger in the air, settle in the water, and impact everyone nearby. It’s time we treat spray sunscreen the same way we treat secondhand smoke: as a public health threat.

Barton Springs isn’t just a swimming hole—it’s a cherished natural oasis in the heart of Austin and a refuge for both people and wildlife. But spray sunscreens, often chosen for their convenience, contain harmful chemicals like oxybenzone and octinoxate. These substances are linked to hormone disruption, coral reef destruction, and even increased cancer risk. The science is clear: these chemicals don’t belong in our bodies—or in our springs.

Every spritz sends toxins into the air and water, threatening the sensitive ecosystem of Barton Springs and exposing swimmers, sunbathers, and children to unnecessary risks. We cannot allow this to continue.

There’s a better way. Mineral-based sunscreens with zinc oxide or titanium dioxide offer powerful UV protection without the dangerous side effects. They’re safer for our health, better for the environment, and the responsible choice for anyone who loves Barton Springs.

That’s why we’re calling on the City of Austin to ban chemical spray sunscreens at Barton Springs. This simple action will protect our natural treasure, keep our community safe, and ensure a healthier future for everyone who enjoys this beloved place.

Our goal is to gather 20,000 signatures to present to the City Council. We need your voice. Sign the petition today and help us make Barton Springs a cleaner, safer, and healthier place—for ourselves, our children, and generations to come.

Enough is enough. Let’s take a stand. Protect Barton Springs. Protect each other.
