NOONAN, N.D. (AP) - A company hired by the state says it has removed the illegally dumped radioactive oil field waste from an abandoned building in Noonan.
Secure Energy Services manager Robert Krumberger told The Associated Press that all of the waste from was removed from the site Wednesday.
Officials reported the illegal dumping of hundreds of radioactive oil filter socks in late February. They said it's the state's biggest incident to date of illegal dumping of the tubular nets that strain liquids during the oil production process.
Krumberger says the building contained about 45 cubic yards of filter socks, or more than double that of original estimates.
Authorities don't know who's to blame, and the whereabouts of the building's owner aren't known.
The state is paying for the cleanup with oil company fees.
