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

Demolition began Monday afternoon on East Chicago's West Calumet Housing Complex, but the U.S.S. Lead Superfund site still leaves former residents concerned for their future.

Officials from the EPA and other federal agencies will join the city of East Chicago and its housing authority at the event.

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.

Many East Chicago residents are concerned demolition will spread contaminated dust.

The money must be used within a year - though HUD hasn't officially approved the city's controversial demolition plan for the West Calumet Housing Complex.

Carson says the handling of the situation could serve as a model for other contaminated public housing.

One year ago, East Chicago Mayor Anthony Copeland told residents of the West Calumet Housing Complex they had to move out because of lead and arsenic contamination.

The U.S. Department of Housing and Urban Development held a hearing Monday about a plan to demolish the lead-contaminated West Calumet Housing Complex.
