In 1953, Hooker Chemical sold the land that they had been using for toxic waste disposal to the Niagara Falls School Board for $1. The sale deed contained warnings about the chemical waste and a disclaimer of liability. However, planners hastily built schools and homes on the contaminated land to accommodate the city’s growing postwar population. By the late 1970s, residents were reporting a litany of illnesses and birth defects. Scientists discovered high levels of carcinogens in the soil, groundwater, and air. The community mobilized to bring attention to the situation, and President Carter declared a federal health emergency in the area.
