about us
By advocating for the complete remediation of the SSFL, site of one of California’s most toxic and radioactive Superfund sites, Parents Against SSFL aims to protect nearby communities from exposure to the site’s toxic and carcinogenic contamination. PASSFL was founded by mothers of children diagnosed with rare cancers and seeks to reduce, to the greatest extent possible, the number of local families who have to hear the words, “Your child has cancer.”
documentary
The Emmy-Nominated Documentary In the Dark of the Valley is currently offline. It follows members of PASSFL, cleanup advocates, and cancer families as they fight for the complete cleanup of the Santa Susana Field Lab.
values
Cancer doesn’t discriminate - neither does Parents Against SSFL. We intentionally engage in meaningful relationships with people of all backgrounds and value systems.
We are a strictly nonpartisan group.
We prioritize people and relationships.
We always “take the high road” and stay true to the good people we are.
Though we focus on work surrounding the SSFL, we actively engage with many toxic-sister-sites across California and the US.
work we do
PASSFL works to hold the Responsible Parties, elected officials, DTSC, and CalEPA accountable for a complete and protective cleanup, while translating complex scientific information into accurate, accessible, and engaging public education through graphics, social media, art, and other creative tools.
We educate, organize, and empower communities affected by SSFL contamination, protect watersheds, and monitor air pollution to reduce ongoing exposure risks. PASSFL also works to safeguard other communities from the mismanagement of toxic and radioactive waste, collaborates with NGOs and coalitions to drive lasting reform within regulatory agencies, supports communities facing similar contamination worldwide, and advocates for renewable energy solutions to prevent future nuclear harm.
