Four Corners Water Hardness & Quality Report (2026)

Four Corners, Florida, in Lake County — a major central Florida rapidly growing Kissimmee area community (Four Corners is a significant Lake County census-designated place — a rapidly growing central Florida community situated near the convergence of Lake, Orange, Polk, and Osceola counties (the community is named for being near the four-county intersection of Lake, Orange, Polk, and Osceola counties — though the CDP itself is entirely within Lake County); Four Corners is part of the extraordinary growth corridor southwest of Walt Disney World (the I-4 corridor southwest of Orlando — including Four Corners, Clermont, and the Lake–Polk county line area — has been one of the fastest-growing regions in the United States in the 2010s and 2020s; the proximity to Walt Disney World, Universal Studios, and other major central Florida employers and attractions has driven explosive residential development; Four Corners and adjacent communities have experienced population growth exceeding 50% in a single decade)); Four Corners has become one of the most diverse and multicultural communities in central Florida (the Four Corners–Clermont corridor has significant populations of Puerto Rican-American, Colombian-American, Venezuelan-American, and other Hispanic-American groups, as well as substantial Haitian-American and Brazilian-American communities), a diverse Lake County community — draws its municipal water supply via the Lake County Utilities. Water hardness in Four Corners measures 273.5 mg/L — classified as very hard.

Four Corners's very hard supply reflects the central Florida Lake County Upper Floridan carbonate platform's extremely calcareous character. The Upper Floridan Aquifer draws from Eocene calcareous Ocala Limestone with limited softening, producing the very hard 273.5 mg/L.

At 273.5 mg/L, Four Corners residents face significant hard water challenges. Regular water softeners and descaling are strongly recommended. Lake County Utilities consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
