Long Branch, New Jersey, in Monmouth County — a major Monmouth County Jersey Shore resort city (Long Branch is one of the most historically significant resort cities on the Jersey Shore — one of the original elite American beach resorts of the late 19th century; Long Branch was the 'Summer Capital' of the United States during the Gilded Age, attracting seven US Presidents (Grant, Hayes, Garfield, Arthur, Harrison, McKinley, and Wilson all vacationed in Long Branch) and some of the most wealthy Americans of the era; President James Garfield was brought to Long Branch after being shot in 1881 and died there), a diverse Monmouth County community with a significant Latino-American, Jewish-American, and working-class Italian-American population (Long Branch has become one of New Jersey's most ethnically diverse cities), home of a major beachfront boardwalk revitalization (the Pier Village development has transformed the Long Branch oceanfront), and a city with a significant arts and cultural community — draws its municipal water supply via New Jersey American Water. Water hardness in Long Branch measures 184 mg/L — classified as hard.
