Calcium Carbonate in Orlando Florida Water

Unhealthy Levels of Calcium Carbonate in the Water Supply of Orlando Florida Homes

Calcium carbonate is a naturally occurring mineral that can dissolve into household water as it moves through rock and soil. Around Orlando and the greater Orange County area, homeowners commonly notice it as white, crusty deposits on faucets and showerheads, cloudy ice, or water spots on glassware. It can also make skin feel dry or leave hair looking dull—typical signs of scale from moderately hard water that local residents often deal with.

You may see calcium carbonate discussed together with calcium bicarbonate, a related form that remains dissolved until changes in temperature or chemistry cause it to precipitate out as scale. In Central Florida’s warm, humid climate and with seasonal shifts after heavy rains, those changes can encourage minerals to come out of solution and form chalky deposits inside pipes, water heaters, and appliances. Left unchecked, this buildup can restrict flow at fixtures and make cleaning more difficult, so tackling scale early helps keep systems in homes across Orlando neighborhoods — from Downtown to Winter Park and Lake Nona — running well.
