Dawn Chapman is frustrated with the Environmental Protection Agency. For years, Chapman has been advocating for cleanup at the West Lake Landfill Superfund site, two miles from her family鈥檚 home in Maryland Heights. Now the agency has said it needs to push back its previous plans in order to do additional testing.
鈥淭he EPA has had this site for 30 years,鈥 she told St. Louis on the Air. 鈥淚t鈥檚 mind-blowing that they are just now bothering to look for the extent of the waste.鈥
The site, located in Bridgeton, contains radioactive waste from the Manhattan Project. It was illegally buried there in 1973.
In 2018, the EPA announced a plan to remove some of the radioactive material and cap the rest. At the time, staffers told Chapman that they were confident in the testing previously conducted on the site. Today, however, the EPA says the nuclear waste on-site is more extensive than it previously believed.

Contacted by St. Louis on the Air, the EPA said that it intends to finish the drilling and testing by spring, and that 鈥渢he investigation work must be completed to determine where the excavation will take place and where to place the engineered cover.鈥 The more data collected now, the EPA wrote, 鈥渢he shorter the time it will take to implement the remedy.鈥
The agency refused to share further details.
鈥淭here is no reason why the transparency isn't there,鈥 Chapman said. 鈥淚f you can't give me a timeline, that's fine. But what you owe me is a reason why what you're finding means you can't give an accurate timeline.鈥
Chapman co-founded Just Moms STL in 2014 to push for cleanup of the site, which many people believe is linked to health problems in the area. She said the site鈥檚 neighbors are now worried about what the EPA鈥檚 additional testing will reveal.
鈥淚f what they're finding cannot be removed because it's too deep,鈥 she said, 鈥渢hen how come we're not removing what we already know is there 鈥 and putting us at risk?鈥
State Rep. Paula Brown, a Democrat who represents parts of St. Louis and St. Charles counties, wants to see cleanup as soon as possible. Her home is located three miles from the site.
鈥淲e鈥檝e had multiple incidences of cancer, we鈥檝e had deaths in young people, we鈥檝e had deaths in pets. We have people who are now afraid to be out in their yard. They don鈥檛 grow their flowers, they don鈥檛 grow vegetables,鈥 she said. 鈥淭hey鈥檙e always afraid, and I鈥檓 afraid for them.鈥
Both Chapman and Brown said the anxiety of residents who live near the site is palpable. It鈥檚 reignited on days when they can smell the landfill 鈥 especially since the buried radioactive waste is adjacent to the Bridgeton Landfill, home to a 鈥渟ubsurface smoldering event,鈥 or underground fire.
Chapman said she visited the site recently and was impressed by some of the short-term safeguards that had been erected.
鈥淚t's amazing to see the technology that can be put into place quickly, to keep a community safe from the fire by the [potentially responsible party],鈥 Chapman said. 鈥淏ut to think my own federal government can't get out in front of this and has let this sit on the surface for 30 years 鈥 it really affected us.鈥
Chapman plans to head to Washington, D.C., in the coming weeks to attend EPA Region 7 Administrator Meg McCollister鈥檚 congressional briefing on the cleanup timeline. She said she plans to push for answers 鈥 and she鈥檚 determined not to let the EPA off the hook.
"This is our own federal government's waste. They made it, they created it," Chapman said. "Why is it the creator of the waste is silent?"
