The most evident ethical dilemma of this film is the dishonesty of PG&E about the type of chromium in the water, and the consequences that it had on the residents of Hinkley. PG&E hid the truth from the people and allowed them to believe that their water was safe, when all along they knew it wasn’t. Donna Jensen told Erin that they even held seminar for the residents of Hinkley and passed out pamphlets to explain the benefits of PG&E using chromium 3 at their plant. Regular chromium is good for the body and chromium 3 is basically benign, however hexavalent chromium (or chromium 6) depending on amount is toxic and harmful to humans. It can cause chronic headaches and nosebleeds, respiratory disease, liver failure, heart failure, reproductive failure, bone or organ deterioration, and cancer.
