Numerous fire companies are currently investigating the source of the odor that has been reported through the area since late last night. MoreThanTheCurve.com has received eye witness reports, or saw social media reports, of being smelled in Conshohocken, Plymouth Meeting, Roxborough and Bridgeport. The odor is of burning plastic.

According to a DEP report, we posted earlier, the Covanta plant is not the source.

More to come.
