Hundreds of gallons of heating oil spilled into the Bronx River.
Around 7:30 Wednesday morning a jogger in Scarsdale alerted authorities about an oil smell. A stench that's lingered throughout the day.
The leak was traced to a storm drain near downtown White Plains.
County and state environmental crews quickly laid booms across the river to contain the flow of oil and a truck was brought in to skim the surface of the water.
The source of the oil was traced to a building on South Lexington Avenue.
The boiler somehow leaked number 6 heating oil into a storm drain in the basement.
Tenants say there's a history of maintenance issues at the 12-story high rise, where in 1993 a fireman was killed battling an electrical fire.
In all, the leak spread from Main Street to crane road in Scarsdale, a distance less than five miles.
The Bronx River is not a prominent fishery. The concern is more for birds, ducks and geese.
