General Advocacy

Research and learn more about these chemical release sites, how chemical contamination of the env works, how it can affect human health, and who is impacted the worst
Spread the word that this is something that can impact us in the Bay Area
Donate time and/or money to groups who are fighting for Env Justice, healthy environments, and corporate accountability
If someone is moving to the Bay Area, suggest they search the property with the research tools first
If you're not already aware, spend some timing reading about the public health crisis in Treasure Island and Bayview-Hunters Point in San Francisco
Tell the press you want to see more coverage on these topics
Volunteer with and/or donate to Greenaction or ICRT

If You're Concerned

Contact the agencies in charge and ask questions about nearby sites
Talk to CHEJ Technical Assistance if you want help understanding the science from a 3rd party
Talk to your political representatives about Brownfield reform and/or Env Justice
Share your concerns with your friends and on social media, forums, etc.
Request Leadership Training from CHEJ (founded by Lois Gibbs, who advocated for protection from the Love Canal pollution, and that advocacy created the EPA Superfund program)
If you're aware of illegal chemical dumping in Santa Clara County, report it!

This is not a complete list. These are merely some ideas.
