"California’s ban on chlorpyrifos is a great example of how government agencies can work to protect our health," said Max Richardson, Policy Director at PHI's @trackingca.bsky.social. "This study is both a success story and a #roadmap for #PublicHealth action."

We found that in 9 counties, 1 in 5 #pregnant people live within 1km of #organophosphate use and in #Monterey county, that number rose to 1 in 2. Throughout the state, expecting Hispanic/Latine people were most likely to live near organophosphate pesticide use.

The #sanjoaquinvalley benefitted the most from the #chlorpyrifos ban, with total organophosphate use ⬇️ by 74%; in contrast, the #centralcoast, home to much of the country's strawberry and lettuce supply, saw total organophosphate use UNCHANGED comparing pre- and post-ban

As part of our Brawley Health ACTION Environmental Study, we developed a #storyamp titled "Living next to PureGro - Stories from generations of Mexican and Mexican American families living next to the former agrochemical facility" ⬇️ arcg.is/0myK5b0

Between 2020-2021, we examined over 3M SARS-CoV-2 infections and about 50K COVID-19 deaths associated with long-term neighborhood levels of PM2.5. #throughtheyears #dataforaction Learn more about the COVID and Air Pollution Study ⬇️ t.co/erQC7ZEv8Z

In 2021, we designed and tested a filtration system for swamp coolers to reduce #wildfire #smoke exposure and health risks among #farmworkers - seven farmworkers leaders living in SJV also developed videos about their experiences ⬇️ #throughtheyears t.co/HAzoeFkJ7c

From 2018-2021, we provided technical assistance to community-based organizations to set up community #airmonitoring networks. #throughtheyears As part of this work, we also developed #roadtocleanair - a storymap which highlights where community partners work and live ⬇️

Last year, we launched a new data explorer and traffic tool - improving accessibility and usability of our datasets. The data explorer is also now available in Spanish data.trackingcalifornia.org?lang=es #throughtheyears #taw2025 #dataforaction

Since 2020, our Cal-WATCH project has been monitoring #habs in #freshwater bodies in Lake County. In 2023, we communicated to local health officers who issued an emergency alert and led two public water systems to provide drinking water to impacted residents. #throughtheyears

From 2019-2020, California Waterboards ordered water systems to test for #pfas under health and safety codes in CA's #safedrinkingwateract. We mapped results from testing near solid waste landfills, airports, fire training facilities, and other sites. #throughtheyears #taw2025

In 2015, we calculated that preventable environmental health conditions in children cost CA $254M each year and over $10B throughout the child's life. #throughtheyears #taw2025 #dataforaction Learn more ➡️ trackingcalifornia.org/projects/cos...

Our #pesticide in schools report published in 2014 helped protect children from pesticides, including spray buffers and notification systems for schools #throughtheyears #dataforaction trackingcalifornia.org/projects/agr...

In 2010, our WBT was launched - data on 4800 public #drinkingwater systems were made available for use for emergency preparedness, including wildfire response and recovery. Although the tool retired in 2020, the data is still available tinyurl.com/3cv2zxyp #throughtheyears

In 2009, we launched our #pesticide mapping tool - for the first time, pesticide data for all of California is made accessible and usable to the public. trackingcalifornia.org/data-and-too... #throughtheyears

We continue partnering with Big Valley Band of Pomo Indians to monitor for #harmfulalgalblooms #habs in Lake County through our Cal-WATCH project. Learn more about current conditions ⬇️: bvrancheria.com/clearlakecya... #throughtheyears #wetrackthat

Last year, we shared that #farmworkers are at high-risk of #heatrelatedillness and those working in Polytunnels - aka hoop houses - may have an even higher risk. We estimate ~41K work in polytunnels along the central coast #wetrackthat #throughtheyears t.co/AdQAkcGJCm

For over 20 years, the CDC's National Environmental Public Health Tracking program has been used to empower people to understand the connection between health and environment. Topics that have been #tracked include extreme heat, childhood asthma, air quality, and more #throughtheyears
