Tapwater Analysis Project (TAP): Testing Chemicals in Drinking Water in California

California drinking water is threatened with chemical contamination from multiple sources. This project will test tap water at the homes of California teachers living in multiple parts of the state for pesticides and other chemicals that are known or suspected carcinogens, endocrine disruptors, or that may be linked to cancer

Fire and Water Study: Drinking Water in the Area Affected by the Camp Fire

The 2018 Camp fire burned much of Paradise and nearby areas, Returning residents reported odors in the drinking water. Testing found benzene and other volatile organic compounds in the water. We tested at the tap at about 130 homes, returned results to residents, and are investigating what happened and how to prevent it from recurring.

California Green Chemistry Evaluation Project

California has unique laws intended to protect public health and exceed federal protections against pollution and toxic chemicals. Two laws enacted in 2008 built on a foundation of other policies related to clean air, clean water, and children’s health protection: AB 1879 established the Safer Consumer Products Program at the Department of Toxic Substances Control (DTSC) and SB 509 established the Toxics Information Clearinghouse. The laws focused on green chemistry with the goals of providing more information about chemicals in products and encouraging substitution of toxic chemicals with less toxic or non-toxic alternatives. A decade later, this project evaluated the progress made under these two laws, which collectively enacted the California Green Chemistry Initiative (GCI). The project also considered how the GCI addresses breast carcinogens.

Bringing down barriers to vaccine access

Structural and systemic barriers mean that the people who are hardest hit by the COVID-19 pandemic—including Black and brown people, immigrants and essential workers—can face the biggest barriers to accessing vaccines. Build skills for boosting vaccine access, with resources, toolkits, training materials and more.
