EPA to Test Sites in Ohio Child Cancer Cluster The Environmental Protection Agency is taking another look at what's behind mysterious cancers in rural northern Ohio that have sickened dozens of children for more than a decade. Environmental investigators plan to test soil, air and water samples at dump and manufacturing sites just south of Lake Erie, where at least 35 children have been diagnosed and four have died from cancer since the mid-1990s. State regulators already have done extensive testing at many of those sites without finding any answers. The EPA says it decided to take action after officials met with families from Sandusky County who have had children diagnosed with cancer. They've been urging the federal government to spend more time investigating the cancer cluster. Still, experts say the odds are against finding a cause.
