Clermont Water Hardness & Quality Report (2026)

Clermont, Florida, the Lake County seat — a major central Florida Lake County community (Clermont is the Lake County seat — one of the fastest-growing cities in Florida, situated in the Clermont Hills, the highest elevation in peninsular Florida; the hills of Clermont are a major training destination for Olympic cyclists and triathletes, and Clermont has become one of the premier multisport training facilities in the world with the National Training Center), home of the Clermont Waterfront Park and Lake Minneola (one of the Chain of Lakes in Lake County — a distinctive system of interconnected lakes that gives Lake County its name; Clermont is surrounded by some of central Florida's most scenic lakes), a diverse Lake County community with a significant Hispanic-American and growing suburban professional population, and a rapidly growing Orlando west suburban community — draws its municipal water supply from the Upper Floridan Aquifer via the City of Clermont Water Division. Water hardness in Clermont measures 97 mg/L — classified as moderately hard.

Clermont's moderate hardness — softer than most Florida aquifer supplies — reflects the Lake County Upper Floridan Aquifer characteristics combined with effective treatment. The Eocene Ocala Limestone at Clermont–Lake County (calcareous marine carbonate) provides the primary supply. City of Clermont applies effective treatment, reducing to the moderate 97 mg/L.

With hardness at 97 mg/L, Clermont residents encounter moderate scale accumulation. Monthly cleaning is recommended. City of Clermont Water Division consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
