The cache is hidden in the old Irvington Reservoir. It's located at the intersection of Harriman and Cyrus Field Road.
The cache is a large thermos with many trinkets in it. Parking coordinates are below under "Additional Waypoints".
The cache has two stages. The first stage is a plague. You must find the year the plague was dedicated (the only year on the plague). Once you find that, you must add that year to 4100275 for the north coordinates and add the year again to 07348913 for the west coordinates.
