Trevor’s Law aims to update the federal guidelines for investigating cancer clusters. But it is unclear if the law will do what the parents hope it will.

In the past decade, as many as 24 children in the small city of Franklin were diagnosed with rare cancers. Their parents want the federal government to declare a cancer cluster and investigate. But defining a cancer cluster — so it can be investigated — is complicated.

Franklin's redevelopment commission reached an agreement last week to spend $850,000 to buy a key piece of land and relocate two businesses for the project.

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.
