Next City: The High Cost of Radium Contamination in Cities, October 2, 2014


A former Naval Air station in the city of Alameda, Calif., was contaminated by the radioactive paint applied to aircraft dials and other equipment in the 1940s and ’50s. The chemical waste was dumped down storm drains. In 2010, the Navy finished replacing thousands of feet of the most seriously contaminated sewer lines leading to a lagoon. Two years later, the dredging of the lagoon was completed.
