Air monitoring in north Toledo continues after the chemical leak that evacuated residents last week, and the latest readings are reassuring, the City of Toledo reported in an update Monday evening.

The U.S. Environmental Protection Agency's mobile Trace Atmospheric Gas Analyzer laboratory — one of only two such mobile labs in the country — detected an extremely low level of glycidyl methacrylate below reporting and screening levels. The lab sampled the air around the detection area for an hour afterward with no additional detections, then continued its established route through surrounding neighborhoods with no further detections, the city said.

The EPA has created a public data viewer so residents can click air-monitoring locations on a map and see summary tables. The EPA and Ohio EPA have begun oversight of cleanup activities at the response site.

The monitoring follows the October 20 failure of an approximately 5,500-gallon intermodal tank that released glycidyl methacrylate, prompting evacuations within one mile and later a three-mile shelter-in-place order. Evacuation orders were lifted October 23. This story is a follow-up to our earlier report on the all-clear.
