For decades, families living near the Stringfellow site have carried the burden of pollution they did not create. CCAEJ has been working to ensure transparency, accountability, and real protections for our community.
What is the Stringfellow site?
The Stringfellow Superfund Site, also known as the Stringfellow Acid Pits, is a former hazardous waste disposal facility
located in Pyrite Canyon near Glen Avon, now within Jurupa Valley. From 1956 to 1972, industrial liquid wastes were dumped into unlined pits. The site was added to the federal Superfund National Priorities List in 1983.
Why is this an environmental injustice?
Stringfellow represents decades of environmental harm imposed on working-class communities and communities of color. Residents were not informed or protected, and many continue to live with unanswered questions about health and safety.
What's Happening?
Cleanup and monitoring are led by the California Department of Toxic Substances Control with oversight from the U.S. Environmental Protection Agency. CCAEJ monitors these actions and advocates for community-centered accountability.
-
1956–1972: Hazardous waste disposal operations​
-
1972: Site closed after leaks and contamination concerns​
-
1983: Added to the federal Superfund list​
-
1980s–Present: Cleanup actions, monitoring, and ongoing community concern​
-
Today: Residents continue to demand stronger protections and accountability
CCAEJ is calling for:
​
-
Full transparency in all testing, modeling, and cleanup decisions
-
Plain-language explanations of risks and findings
-
Meaningful community engagement—not last-minute notice
-
Health-protective standards, not minimum compliance
-
Land-use safeguards to prevent new harm
-
Long-term accountability, not short-term fixes
We organize residents, attend agency meetings, submit formal comments, and elevate community voices that have been ignored for far too long.
