Radioactivity in stormwater runoff
State says radioactivity in stormwater runoff is not from West Lake Landfill waste  
By Bryce Gray St. Louis Post-Dispatch

From the article:
Quote:Analysis has shown that radioactivity found in stormwater runoff from West Lake Landfill could not be linked to decades-old radioactive waste at the site, the Missouri Department of Natural Resources says.  

"Based on the results, there's no indication that it's coming from West Lake materials," said Branden Doster, the chief of MDNR's federal facilities section, an office that helps provide oversight of properties like West Lake, which is in the process of being remediated through the Environmental Protection Agency's Superfund program. "We couldn't link it to the landfill waste."

The origins of the radioactivity remain unclear. Doster said that while some radioactivity would be expected from natural sources, the department is unable to quantify that amount.

The regional EPA office agreed with the state agency’s interpretation of the data. The EPA has said since June that the levels of radioactivity found in runoff from the site do not put the public at risk.

“It would be a good idea to require testing for radioactive stormwater runoff,” said Ed Smith, policy director for the Missouri Coalition for the Environment.

Smith noted that he thinks most material that can leave the site through stormwater runoff has probably done so over the last 40-plus years.

“Nonetheless, this stuff sits on the surface and needs to be monitored,” he said.
MDNR report

They're sure the radiation is not from West Lake landfill but they can't say where it's from.  Well, where is it from?  Did it just fall out of the sky?  

The author of the article missed the mark; the storm runoff is still more radioactive than it should be and this testing wasn't comprehensive enough to reveal the source of the radionuclides found.  We aren't informed by the article.  We are led to believe it's not the landfill because it's had forty years to wash radionuclides downstream; and, of course, it includes the mandatory phrase 'the public is not at risk' to play it safe.
