24/7 Biohazard and Crime Scene Cleanup in Harrison, NY

Harrison is a coterminous town and village in Westchester County, New York — a single municipality that has operated as both a town and a village since 1975 — located about 22 miles northeast of Manhattan.

Harrison was established in 1696 by a patent granted by the British government to John Harrison and three others, who had bargained with local Native Americans to buy land above the old Westchester Path trail.

Local folklore holds that John Harrison was given 24 hours to ride his horse around all the land he could claim, and that the claim's odd shape came from the horse's refusal to swim or wet its feet.

Harrison was formally organized as a town on March 7, 1788, and in the early 1970s it converted itself into a hybrid town/village largely to block its Purchase section from seceding and incorporating on its own.

Harrison had a population of 28,218 at the 2020 census, and Census Bureau figures for 2020-2024 count about 9,200 households averaging 2.88 people each.

Harrison is one of the wealthiest communities in the United States, with a median owner-occupied home value of about $1,010,700 in Census Bureau figures for 2020-2024.

Harrison's hamlet of Purchase is home to Purchase College of the State University of New York, founded in 1967 by Governor Nelson Rockefeller on a 500-acre campus as a home for conservatory-level arts training within a public liberal arts college.

Purchase, in Harrison, is also home to Manhattanville University, a private university founded in 1841 in Manhattan that moved to the former Whitelaw Reid estate in Purchase in 1952, on a 100-acre campus designed by Frederick Law Olmsted.

Harrison covers about 17.4 square miles in total, of which about 0.6 square miles is water.
