MINNEAPOLIS (AP) — Residents of a southeast Minneapolis neighborhood are being warned about potentially harmful vapors.
The Minnesota Pollution Control Agency and the state Health Department sent letters Thursday to Como neighborhood residents.
The soil vapor is TCE, and officials have known for more than 30 years about it contaminating groundwater in the area. State officials say the industrial solvent was used at a General Mills research facility.
Minnesota Public Radio (http://bit.ly/16KCfQV ) reports TCE exposure has been linked to cancer.
Officials say groundwater had been treated until September 2010 as the plume stabilized. Soil vapor testing began as part of the cleanup.
Last month, data showed TCE in soil gas samples. If testing determines the levels in soil below homes and businesses are unsafe, General Mills has agreed to install vapor ventilation systems.
