Anniston, Alabama: The Town Monsanto CONTAMINATED for 40 Years

Anniston, Alabama is not abandoned. It is a working American city that spent decades living beside one of the most infamous chemical contamination stories in the country.

For years, PCBs manufactured at the local plant flowed into ditches, creeks, floodplains, landfills, and neighborhoods. Residents on the west side of town lived with that contamination long before most of them were ever told what had happened. The core fact is simple: PCBs were produced in Anniston from 1929 until 1971, and the consequences still have not fully ended.

How Anniston Became a PCB City

PCB production in Anniston began in 1929 under Swann Chemical. Monsanto bought the operation in 1935 and turned the plant into one of only two PCB manufacturing sites in the United States.

The chemicals were sold under the Aroclor brand and used in transformers, capacitors, hydraulic systems, and other industrial applications because they were stable and resistant to heat. Those same traits made them a long-term environmental problem. PCBs do not break down quickly. They persist in sediment, soil, wildlife, and human bodies.

According to the EPA, the vast majority of PCB contamination in the Anniston area came from operations at the former Monsanto plant. Waste moved off site through landfills, drainage paths, surface runoff, and contaminated sediment carried into Snow Creek and downstream waterways.

What Monsanto Knew

The public story in Anniston was not just about pollution. It was about concealment.

Internal company records later cited in investigations and lawsuits showed that Monsanto understood PCB contamination around the plant was serious decades before the full scope became public. Sampling in and around Snow Creek and Choccolocco Creek showed contamination in water, sediment, fish, and animals. Company documents also reflected concern about legal exposure and public reaction.

That matters because Anniston residents were not dealing with an accidental one-time spill. They were living inside a long industrial release pattern that overlapped with delayed warning, weak disclosure, and years of corporate damage control.

West Anniston Paid the Price

The contamination burden fell hardest on neighborhoods closest to the plant, especially in West Anniston. Soil, dust, creek sediment, and locally caught fish all became exposure pathways.

In November 1993, Alabama issued its first fish consumption advisory for parts of Choccolocco Creek after testing found high PCB contamination. By then, people had already spent years fishing, gardening, raising animals, and living with exposure they had not been clearly warned about.

The health concerns did not disappear once testing finally expanded. Federal and academic studies later found elevated PCB levels in Anniston residents. In the Anniston Community Health Survey conducted from 2005 through 2007, 765 adults were tested, and researchers found PCB body burdens well above levels typical of the general U.S. population. Later analyses reported associations between PCB exposure and conditions such as hypertension, diabetes, and abnormal lipid levels in some groups.

Lawsuits, Settlements, and Federal Cleanup

Public outrage in Anniston eventually turned into one of the most important environmental court fights of its era. In 2002, an Alabama jury found Monsanto and its corporate successors liable on multiple counts related to the contamination. In 2003, the companies reached a broad settlement covering more than 20,000 residents, with the total value commonly described at roughly $700 million or more depending on how cash payments, programs, and cleanup obligations were counted.

The legal case was only one part of the response. EPA became formally involved in 1999 and has continued to direct cleanup under the Superfund Alternative Approach. The site was treated as National Priorities List caliber, even though it was not formally placed on the NPL.

Cleanup was split into multiple operable units covering residential areas, non-residential areas, the active and former plant property, and downstream waterways. EPA signed major decision documents for residential and non-residential areas in 2017, and on December 20, 2024 approved the Record of Decision for Operable Unit 4, covering Snow Creek, Choccolocco Creek, and downstream floodplain areas. That date matters because it shows how long this contamination has lasted: PCB production ended in 1971, but federal remedy decisions were still being issued more than 50 years later.

Why Anniston Still Matters

Anniston is one of the clearest examples of how industrial contamination becomes a social map. The pollution was real, but so was the geography of who absorbed the risk, who got warned late, and who had to fight for proof.

This is why Anniston still matters even now. It was not just a toxic site. It was a city where a corporation made a durable chemical, released it for decades, failed to fully level with the people living nearby, and left residents to carry both the health burden and the legal burden of forcing accountability.

The factory story ended in 1971. The contamination story did not.
