Biohazard and Pathogen Disinfection in Whippany, NJ

Whippany is an unincorporated village located within Hanover Township in Morris County, New Jersey, with its own post office (ZIP Code 07981) and fire department but no separate municipal government.

Whippany's name derives from 'Whippanong,' the Lenape word interpreted as 'place of the willows,' for the trees that grew along the banks of the Whippany River.

The name was first recorded in a 1676 deed reference to 'A Place Called Whippano,' and Hanover Township formally commemorated the 350th anniversary of Whippany in 2026.

Colonial records applied the name 'Whippenny' to a vast territory stretching from the Passaic River toward Lake Hopatcong — the predecessor of Hanover Township, from which all 39 of Morris County's municipalities were ultimately formed.

In 1720 the royal colonial government replaced the name Whippenny with 'Hannover,' in honor of King George I of the House of Hanover, while the original settlement kept the name Whippany.

Hanover Township was incorporated on February 21, 1798, and Whippany and Cedar Knolls remain its two principal communities, roughly separated by Interstate 287.

Hanover Township counted 13,712 residents at the 2010 United States census.

During the Revolutionary War, George Washington and his troops frequently camped in and marched through the Hanover Township and Whippany area.

In the 19th century Whippany was an industrial village where J. E. Ashworth & Sons operated a woolen blanket mill on the Whippany River.

Whippany is home to the Whippany Railway Museum, which preserves Morris County railroad history beside the Morristown Line tracks.
