He gained national attention for his legal battle against the chemical company DuPont, which involved the contamination of drinking water with perfluorooctanoic acid (PFOA). His efforts highlighted the dangers of industrial chemicals and their impact on public health. Bilott's case began in the late 1990s when he represented a farmer whose cattle were dying due to toxic waste from DuPont. His investigation revealed widespread pollution and led to a landmark class-action lawsuit. Bilott's work has been influential in raising awareness about environmental issues and corporate accountability.
