32 Chicago homes to be tested for Thorium

May 10, 2008 - Additional testing will be required for more than 30 West Chicago homeowners to determine whether their properties are contaminated with thorium, a U.S. Environmental Protection Agency official said Friday.

The contamination led to two cleanups in the 1980s and 1990s.

mong the homes slated for more testing for thorium is that of Sandy Riess.

Riess and her husband moved out of their home last September after radioactive levels 300 times above what's considered safe were discovered on her property. Tronox, the successor to Kerr-McGee, has been paying for some of the family's living expenses.
