Tracking Awareness Week 2025!

July 2025

Join us in celebrating the 10th annual Tracking Awareness Week, July 7-11, 2025. This year's theme is Through the Years - a reflection of all we have accomplished over 20 years as a program.

During Tracking Awareness Week, Tracking California and other states and jurisdictions funded by the CDC's Environmental Public Health Tracking Program will come together to highlight the various ways public health professionals have used data for action.

We've also worked with data behind the scenes to advance pesticide safety near schools, improve lead testing in children, inform local health officers about harmful algal blooms at Clear Lake, and support community partner efforts across the state to monitor air quality and advocate for healthier air.

Follow along on social media throughout the week as we and other Tracking programs across the country reflect on our work to provide #DataForAction #ThroughTheYears.

You can find us on Facebook, X, and BlueSky, as we share messages about data, tools, resources, program successes, and utility of the Environmental Public Health Tracking Program.
