On Thursday’s “St. Louis on the Air,” host Don Marsh brought together several different parties to talk about ongoing community concerns over radioactive contamination at the Bridgeton and West Lake landfills. He was joined by:

Véronique LaCapra - St. Louis Public Radio’s science reporter. She has reported extensively on the situation at both landfills

Dawn Chapman - Citizen activist

Mike Petersen – Chief of Public Affairs, U.S. Army Corps of Engineers

Henry Royal, M.D. – Professor of Radiology and Associate Director, Division of Nuclear Medicine, Washington University School of Medicine

Maria Chappelle-Nadal – Missouri Senator for the 14 th district, who has spoken out about contamination at the landfills. On the show, she announced her resignation from the University City School Board in order to focus on the situation at the Bridgeton landfills.

Russ Knocke - Director of Field Communications & Public Affairs at Republic Services

On the show, while talking about radioactive contamination in the area, Maria Chappelle-Nadal announced her resignation from the University City School Board to focus on the situation. “While I have totally enjoyed serving the people of University City on the school board, and you all know how important education is, I also believe that the livelihood of every St. Louisan is equally important and that’s where I want to put my time,” Chappelle-Nadal said.

Earlier this month, Missouri Attorney General Chris Koster released reports that radiation from the West Lake Landfill in Bridgeton has spread to neighboring properties. The reports also suggested that an underground fire at the neighboring Bridgeton Landfill is moving toward radioactive waste and could reach it as soon three to six months. The landfills’ owner, Republic Services, has vehemently maintained that the situation at the landfills is under control.

“The fact is that the EPA, the DHSS and a number of experts ranging from air or water or land continue to state that the site is safe and nothing rises to the level of a public health concern,” Knocke said.

It should be noted that Attorney General Koster, the Missouri Department of Natural Resources and representatives from the Environmental Protection Agency declined to participate in the discussion.

The concern in the surrounding communities persists.

“There are no studies out there that show chronic, low-level exposure to radiation,” said Chapman. “They don’t exist. That’s what we’re talking about here, we’re not talking about the fire hitting the waste and making these particles airborne and you going to Target and getting a mouthful. We’re talking, you have a community living on top of this, you have 92 homes, them breathing it in for the next five years when they go out to play.”

On Thursday, at 6:30 p.m. at 12567 Natural Bridge Rd., a town hall meeting will be held to address community members’ concerns.
