I visited this site years ago and was aghast with the dilapidated industrial condition. It looks like a rustbelt site from the worst stretch of Newark or Paterson.
I have reason to believe that there is severe chemical contamination and that it is directly leaching into the Hackensack River.
This property should have been listed as a SUPERFUND site, and should receive greater attention from the Hackensack Riverkeeper group.
Other than by canoe or walking up the railroad tracks from New Bridge Landing, it is accessible only via a winding driveway that cuts between two houses on Kinderkamack Road.
