Multiple stakeholders are introduced in this film, such that either directly worked at the plant or had family who worked there, such that were academically interested in the matter, or such that were concerned about their community.
Paul Mitchell was a former electrician at Mallinckrodt, he was not informed about potential dangers and states that "no one there knew what uranium was". Further, he talks about noticing how colleagues got cancer, at beginning he did not find this unusual but then became weary after one colleague who had been very young and fit also was diagnosed with cancer.
Further, Brooks Davis tells her family story, she is the daughter of former plant workers (I think the father worked there for about 15 years, while the mother worked there for 1 year). Her father had been working in "hot areas" and was shifted to other areas in the plant whenever his exposure to radioactivity had been exceeding permitted levels for some time, and then was moved back after a short period of "cooling down". He got lung cancer at age 40, and was struggling with the disease for years, which caused him much bodily and emotional pain, finally he died in 1978. Her mother, who lived in poverty as a result of losing her husband so early and having to provide for her children, tried to claim to be entitled for compensation but was denied this repeatedly for bureucratic reasons until she wrote a letter explaining her situation.
Clearance Schneider was a health and safety inspector at Weldon Spring, he explains that one had to wear a badge and a white uniform when working at the plant, and if something was not right with the badge (that recorded nuclear exposure), it was taken off. He reports an incidence with a hydrochloric acid cloud that was released into the air and hovered over the neighborhood. He had skin cancer, but you could not confide this to anyone as he was afraid to lose his job, and when the company closed he reports that one was not allowed to leave the country for 3 years.
Obie Young was a chemical operator and reports that when his job was eliminated, he got several months of pay such that he would not need another job for a while, because if he had started a new job they would ask for tissue samples and find out that radioactivity was much too high in his body.
Another stakeholder is the organization "St. Charles County against hazardous waste" with his president Dr. Michael Garvey. They were concerned about contamination at Weldon Spring site, and demanded that the voice of concerns were heard at citizen meeting.
Gary Ferguson, a laborer who was involved in the cleanup of the site, reports that Geiger counters went through the roof but "they told us it was not dangerous". Further, he reports that containers with stored chemicals were disintegrating. Every day he worked at the cleanup, he had a bloody nose, but when he told his supervisor this person respondet that he should not talk to anybody about it, because otherwise he would get fired. He therefore decided not to confide in anybody, because he "had to pay his bills".
Gerald Kleba, a priest in the community, who noticed that many children in his precinct were sick and died, went on a Weldon Spring "tour". He was surprised that people on the other side of the fence concerned with the cleanup had moon clothes on, but people on the tour on the other side of the meshed fence were wearing everyday clothes and not informed about potential dangers. This shocked him, and encouraged him to engage in communal activities to raise attention to the danger of chemical and nuclear waste in the neighborhood.
