Washington state's Hanford Nuclear Reservation is one of the most contaminated places in the United States, with the government recently disclosing that six large underground tanks are leaking up to 2,000 litres of radioactive liquid per year. The news has alarmed environmentalists, who fear the radioactive material could pass through groundwater to the nearby Columbia River. Officials say the leaks pose no immediate danger to the environment, or to people in the area. Richland, the town nearest to Hanford, is so closely tied to the site that the local high school basketball team is called the 'Bombers'. The town is also economically dependent on the clean-up effort and people there have learned to live with the nuclear waste next door. Al Jazeera's Rob Reynolds reports from Hanford, Washington.
