The State Health Department and the Department of Environmental Management say they have not found enough evidence to link cases of child cancer around Franklin to a cancer cluster.
ISDH officials say they studied numerous factors, and IDEM studied water, soil, and other factors but found nothing in the area that would be cancer-causing.
There had been concern among some residents that contaminated water was leading to an increase in the number of cases of childhood cancer.
Officials say they looked at more than 100 individual cases from 1999 to 2013 and found that the numbers were not above average or concerning enough to declare a cancer cluster.
To date, there has never been a cancer cluster in Indiana, despite several dozen investigations.
