Right now, the Environmental Protection Agency (EPA) doesn’t have enough information to determine whether excavation is impacting lead levels in zones 2 and 3. However, EPA’s preliminary data shows that, before excavation, 18 homes had lead levels in tap water that exceeded the action level of 15 parts per billion. There is no safe level of lead exposure.
EPA has notified the Indiana Department of Environmental Management (IDEM) and the City of East Chicago of these results. IDEM has been actively working with the City to optimize the dosage of the current corrosion control treatment. The treatment reduces lead leaching by forming a protective coating on the interior of the pipes, with the ultimate goal of reducing lead levels in your home.
