The news team learned that several people complained the EPA never told them about toxic chemical waste contamination in their residential area. The waste was dumped near their homes or contaminated their water. Some residents eventually found out as they started to fall sick, but the EPA had known about the exposure for decades. The news team obtained the EPA database, mapped out where contaminants were concentrated and spotted the affected people. The source of contamination is traced to two steel companies. As a result, legislation is on the way, and authorities are testing soil and water.
