Two groups are seeking a federal investigation about why toxic contamination persisted in an Indianapolis suburb decades after it was first discovered.

The U.S. Environmental Protection Agency told city officials that it's monitoring the site formerly used by Amphenol, an electronics manufacturer.

Experts looking for cancer-causing chemicals in Franklin say, so far, they don’t see a widespread problem in the city. But recent sampling results show more investigation is needed.

Some residents think contamination from the site could be responsible for rare blood and brain cancers in the area. The Environmental Protection Agency is already collecting samples in the same area.

The Indiana Department of Environmental Management will sample about two dozen private wells in the Paris Estates subdivision on Monday, according to the Johnson County Health Department.

IDEM and the State Department of Health say they don’t see the need for testing in more homes or schools, at this time.

The school corporation says none of the samples were above the Environmental Protection Agency’s protective levels for health.

TCE is used to degrease metal and to make other chemicals like refrigerants. It's just one of the chemicals found at the Amphenol industrial site in Franklin.

Law enforcement agencies in the cities of Franklin, Jeffersonville, Lawrenceburg and East Chicago and Harrison County each received more than $11,000 in funding.

Crews are upgrading the line through Franklin as part of Louisville & Indiana Railroad's plan for faster and longer trains between Indianapolis and Louisville, Kentucky.
