Dr. Richard Foster was the fish laboratory supervisor at Hanford. He talks about inspection of organic matter in the Columbia River prior to and after the construction of reactors at the Hanford site. Foster describes DuPont’s central role in taking necessary precautions, highlighting their professionalism and efficiency. He discusses how any leaks were primarily into the atmosphere rather than into the water. Also, he brings up research done at the University of Washington regarding X-ray radiation and its effect on fish. The extent to which safety and environmental harms were taken into consideration, according to Foster, was advanced for its time. The state of Washington, and the country as a whole, had very little awareness regarding the concept of ecology or water pollution control.
