Protection Agency's Chicago office.

Local, state and federal state tests found that groundwater under 40 
blocks east of downtown was contaminated with tetrachlorothene (PCE) and 
trichloroethene (TCE), both used to degrease machinery. PCE, often

...

When PCE or TCE are exposed to water, they change to vapor, which 
migrates through the soil. The vapor can enter basements or houses 
through cracks in the foundation. Testing earlier this year found 16 
structures, including St. Patrick School, with higher than acceptable 
levels of PCE or TCE vapor.

The EPA has since installed a venting system in all 16 structures to 
take care of the problem.
