Science Action Network

Advancing Health in Chemical Policy

We launched the Science Action Network for Health and the Environment to help prevent toxic chemical exposures, improve public health, and support environmental justice. Our 200+ members use their expertise to ensure that U.S. policy protects health, the environment, and future generations.

Recommendations to Strengthen EPA

To help EPA put science and public health front and center, PRHE collaborated with top scientists and chemical policy experts from around the country to develop evidence-based recommendations to improve hazard and risk assessment, and prevent harms from chemicals and pollutants.

Strengthening the Chemical Regulatory Process

The SAN convened an interdisciplinary group of experts, including EPA veterans, to recommend improvements in how science is used in decision-making to prevent harmful chemical exposures.

Public comments

We monitor EPA and other regulatory body actions and comment on whether they are following the best science and protecting health. Public comments are essential to holding government agencies accountable.

With a decade of success organizing environmental health scientists in science and policy-making, PRHE pioneered and launched the Science Response Network in 2017, now Science Action Network for Health and the Environment. The Network has grown to 200+ members and includes experts from around the world who monitor and submit public comments to EPA and other US Agencies. Under the guidance of PRHE’s Director Dr. Tracey Woodruff, PhD, the Network is led by PRHE's Science, Policy and Engagement team.
