Florida water hardness

Understanding Florida

Why local comparisons matter here

Florida's carbonate aquifers supply many communities, while large urban areas may also use surface water, shallow aquifers, desalination, or blended sources. Coastal conditions add another layer of variation.

In this index, very hard is the largest category, covering 343 of 498 profiles with hardness data. The state median is 280 PPM, but the full indexed range is 42.2–2300 PPM.
