6. During the 1940s, Hooker Chemical and Plastics Corporation used Love Canal, a sparsely populated area located in Niagara Falls New York, as a chemical dump site lining it with impermeable concrete. However, residential and school constructions in the 1950s resulted in many breaches of the protective lining, gradually seeping out toxic wastes into the soil polluting the groundwater and the air. Of the 240 buried chemicals that had been identified, eleven were suspected carcinogens, notably benzene, which can cause serious health problems. According to a report, the residents were stricken with a disturbingly high rate of miscarriages, birth defects, nervous disorders and cancers. Love Canal has become a testimony to one of the greatest human blunders and of the constant need for seeking environmentally safe ways of managing toxic waste.
