Orlando's water is officially classified as "hard" to "very hard," typically measuring between 120 and 180 parts per million (ppm), or roughly 7 to 10 grains per gallon. This hardness is due to the city's primary water source: the Floridan Aquifer. As water filters through the underground limestone layers of Florida, it naturally picks up high concentrations of minerals like calcium and magnesium. While this water is perfectly safe and even healthy to drink, the high mineral content has several noticeable effects for residents and visitors. You may notice "scale" or white crusty buildup on faucets and showerheads, and your soap or shampoo may not lather as easily as it does with soft water. For travelers, the hard water can sometimes make hair feel slightly "crunchy" or dry after washing. Many homes and hotels in the Orlando area use water softening systems to mitigate these issues, but the base municipal supply remains consistently hard. If you have sensitive skin or hair, using a clarifying shampoo or a heavy-duty moisturizer during your stay can help counteract the drying effects of the local mineral-rich water.
