BRIDGETON, MO (KTVI)-Teams are gathered at the Bridgeton Athletic Complex for Monday night games. But earlier in the day, teams mobilized at the complex for a non-sporting event. They hope to determine if there’s a threat for exposure to radiological material.

Two teams from Midwest office of the Environmental Protection Agency will screen the grounds for contaminants. They spent Monday coordinating the game plan.

The screening is the result of citizens concerns about the possible risk of radioactive material from the nearby West Lake Landfill. The teams will take some surface level readings from a scanner that’s pushed across the surface. They’ll also collect some selective soil samples.

When a citizen’s group conducted an independent screening, their results showed a spike.

On Monday, some of those environmental advocates showed the Feds where the private samples were collected from. So now the EPA will spend the entire week in Bridgeton conducting their own tests.

Ben Washburn, with the EPA, says, “They’ll be conducting tests for the gamma screen on the surface. Some of the soil samples will look for the alpha particles.   From there we’re going to be able to make a judgment based on scientifically valid data, collected by professionals, using professional equipment.”

It’s going to be at least 30-60 days before the results are in. In the meantime, the Bridgeton Athletic Complex has seen the cancellation of at least one tournament and a few teams have refused to play on the fields. The EPA insists the fields are safe for play.
