POISONED USA: Medical Sterilizer Exposed Thousands to Cancer-Causing Chemical

Sterilization Services of Virginia last year received a presidential exemption from EPA rules that would have required the company to update its equipment and use a continuous emissions monitoring system. In April, a faulty valve on the roof of its facility in Henrico County emitted more than 500 pounds of carcinogenic ethylene oxide. Residents say they weren’t notified of the release.
