Protect Our Bay: Demand a Clean, Safe United Heckathorn Superfund Site

From 1944 to 1966, chemical companies dumped DDT and dieldrin into the Richmond Inner Harbor. A mid-1990s EPA cleanup failed. Contamination has exceeded cleanup goals every year since 1999, leaving more DDT now than before the cleanup. The EPA has worked on a second plan since 2012 and has said they will release a draft for public comment in mid- to late September 2026.

The Problem: The EPA is legally required to involve the community, but it has shut residents out. This is an unfair burden on a community that has endured over 80 years of cancer-causing toxic pollution and waited 13 years for a real, lasting solution.

Our Solution: When federal regulators failed to act, a coalition of the Richmond Shoreline Alliance, SF Baykeeper, and the Sierra Club SF Bay Chapter stepped up—developing a Community Cleanup Plan grounded in local knowledge and community priorities. The plan has already earned real political weight: the Richmond City Council endorsed it unanimously, 7-0, and Contra Costa County Supervisor John Gioia has backed it too.

Take Action: The U.S. EPA and California Department of Toxic Substances Control (DTSC) need to hear from you.

Send a message telling regulators to adopt this community-backed plan—because Richmond deserves a toxic-free future.

Dear Officials at the US EPA and California DTSC, I am writing to urge you to adopt the Community Cleanup Plan for the United Heckathorn Superfund Site in Richmond, CA. The persistent contamination of DDT and dieldrin at this site continues to threaten both human health and local wildlife. Exposure to DDT in humans is linked to increased risks of breast cancer, infertility, liver cancer, diabetes, and developmental delays, with significant multi-generational impacts on obesity and hypertension in grandchildren of exposed individuals. It is unacceptable that we, and the Bay's marine ecosystems, remain exposed to these highly toxic, bioaccumulative chemicals. We want the site cleaned up to levels that no longer pose serious health risks to both humans and wildlife. A full cleanup, as outlined in the community plan, is imperative to resolve the problem at its source, once and for all. We expect you to fulfill your obligation under CERCLA, the federal government's Superfund Act.
