JEFFERSON COUNTY, Colo. (CBS4) – New information details how much pluntonium scientists found in a dirt sample from Rocky Flats National Wildlife Refuge. The Colorado Department of Public Health and Environment sent a letter to community on Tuesday which lives near the controversial Jefferson Parkway; a future four-lane tollway.
Health experts say one soil sample, taken from Indiana Street between 96th and 120th Avenues, was measured to have 264 pCi/g (picocuries per gram) of plutonium. The acceptable standard for the cleanup after the plant closed is 50 picocuries per gram.READ MORE: Denver Public Safety Manager Murphy Robinson Accuses City Councilwoman Candi CdeBaca's Chief Of Staff Of Discriminating Against A White Staff Member
State experts say they do not believe there is a threat to public health.
Another portion analyzed from the same soil sample measured 1.5 pCi/g of plutonium. Experts say more sampling and testing are needed to determine what this means for long-term risks.READ MORE: Hazy Skies Over Downtown Denver Could Become A Regular Thing During The Summer
The concern moving forward is many more contaminated particles exist along Indiana Street and could become airborne during construction of the toll road.
“The department sent the Parkway Authority a guidance letter on regulatory requirements, precautions, and ‘best practices’ should the construction of the Parkway commence… It advises the Parkway to monitor for plutonium in the air and use techniques to minimize fugitive dust from construction,” CDPHE said in the letter to the community.MORE NEWS: Boulder, Fox And Aggie Theaters Ask For Proof Of COVID Vaccine Or Negative COVID Test
