A new study shows the historical blood lead levels of children in East Chicago's Superfund site remained higher than those in the rest of the city.

The EPA said in a statement that it "continues to evaluate data and hopes to announce a cleanup plan for public comment in late summer or early fall."

The site on Indianapolis' southwest side was the location of a retail battery sales store from about 1962 until 2008.

The public voiced frustration about arsenic and lead contamination, demolition of the West Calumet Housing Complex and possible groundwater contamination.

The complex was built on the site of a former lead smelter and two years ago the city and the East Chicago Housing Authority ordered that more than 1,000 residents be relocated.

About 50 people attended Wednesday's public hearing on the plan to cleanup land in and around an East Chicago industrial site.

U.S. Environmental Protection Agency finished removing lead-contaminated soil from 101 properties at the American Lead site in the Martindale-Brightwood neighborhood of Indianapolis.

The EPA said Monday it issued two unilateral administrative orders for residential areas slated for cleanups in East Chicago's USS Lead Superfund site.

The former DuPont site is not a Superfund, but is contaminated with lead and arsenic, as well as zinc and cadmium.

The lawsuit alleges the companies caused property loss, and the residents seek financial damages due to emotional distress.
