[FoxNews] A mysterious stench once again struck parts of Delaware County, Penn., this week, overwhelming residents with its pungent odor and baffling investigators.The smell has recently been reported in towns across the county, including in Glenolden, Tinicum and Upper Darby, just outside of Philadelphia. While no one knows what the elusive smell is or where it is coming from, residents have described it as fuel-like.
Delaware County residents have reported the smell wafting in and out of neighborhoods over the last several months. Last October, the smell shut down several businesses and a school in Chester before striking Brookhaven in December, FOX29 Philadelphia reported at the time.
The most recent stench is consistent with past reports, according to officials, but investigators still can’t find the source.
