At Madison Site, the residents of Calpin streets compiled data of residents living nearby the plant that got cancer. So this was a kind of data collection/ archiving of the residents. They had a list of the illnesses of residents near the plant and they found over 70 cases of cancer on the Calpin streets and 114 Cases of Cancer in the surrounding blocks (around 1h24min). Through this data collection, it was possible for residents to become active and gain the knowledge about what is going on: they became informed and political in this way.
