BRIDGETON, Mo. (AP) — Radiation testing is underway around homes in a St. Louis County neighborhood not far from a Superfund site at a landfill.

The Environmental Protection Agency began screening Tuesday for radiation in the Spanish Village neighborhood of Bridgeton. A couple from the neighborhood filed suit in November, alleging that they have been exposed to nuclear dust.

The neighborhood is near Bridgeton Landfill and West Lake Landfill. Cold War-era nuclear waste was illegally dumped there in the 1970s. Making matters worse, an underground fire has burned in recent years just a few hundred feet away at the adjacent Bridgeton Landfill.

Both landfills are owned by Republic Services, which is spending millions to both contain the fire and to reduce a significant odor.
