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

Yaphank is a hamlet and census-designated place in the town of Brookhaven in Suffolk County, Long Island, spread across about 13.8 square miles along the Carmans River.

European settlement began in 1726, when Captain Robert Robinson built a Dutch Colonial house there, and John Homan's mills on the Carmans River gave the young community its first name — Millville.

The hamlet was renamed Yaphank, from the Native American word Yamphanke meaning 'bank of a river,' after a post office opened in 1846 and officials realized thirteen other places were already called Millville.

The Long Island Rail Road reached Yaphank in 1843, turning the small mill town into a major commercial center almost overnight.

Yaphank was home to Camp Upton, a World War I training camp where more than 30,000 soldiers received basic training in 1917.

Composer Irving Berlin was stationed at Camp Upton and wrote and staged his all-soldier musical revue 'Yip Yip Yaphank' there.

After World War II the Camp Upton site was transferred to become Brookhaven National Laboratory, one of the U.S. Department of Energy's major research facilities.

In the 1930s Yaphank hosted Camp Siegfried, a summer camp run by the pro-Nazi German American Bund that drew up to a thousand visitors a week, and deeds on the former camp land restricted sales to people of German extraction until those covenants were challenged and removed in 2017.

Yaphank counted 5,974 residents at the 2020 census.

Writer and abolitionist Mary Louise Booth, the founding editor of Harper's Bazar, was born in Yaphank — then called Millville — in 1831.
