Over 90 current and former New York residents filed on Thursday a lawsuit against IBM, claiming that the IBM plant’s operations led to chemical changes of the environment, which exposed them and their children to severe contamination, causing congenital affections and even cancer.

The IBM plant in Endicott is held responsible by the plaintiffs for dumping between 1924 and 2002 millions of gallons of harmful chemicals, such as Trichloroethylene, Tetrachloroethylene, Trichloroethane, Benzene and Trichlorotrifluoroethane, near the towns of Endicott and Union.

The dumped substance were allegedly “contaminants and pollutants to the environment and constituted toxins to persons who became exposed to them through ingestion, inhalation or dermal absorption,” according to the suit.

The lawsuit claims the inhabitants continue to be exposed to dangerous vapors up to this date. The computer manufacturer is accused not only of having caused birth defects and cancer, but also of having caused wrongful deaths. More current and former residents of Endicott and Union are expected to file similar lawsuits at the Supreme Court for the State of New York in Broome County.

IBM, who was in charge of the New York plant from 1924 to 2002, has conducted $2 million cleaning operations in the area, but the plaintiffs do not believe that was enough to make things right. The company spokesman Michael Maloney said on the allegations: “As we explained to plaintiffs’ lawyers before they filed this case, these suits have no basis in science or law, and IBM will defend itself vigorously.”

This is not the first time IBM faces such accusations. In 2003, two of its own employees in San Jose, California, claimed that working with chemicals got them sick, which later led to cancer, but the computer company won the lawsuit. IBM representatives say this is the same situation, and the allegations do not have a solid base.
