What Makes Jupiter's Water Unique?
Local geology and source profile
Jupiter, Florida, in northern Palm Beach County on the Atlantic Coast — an affluent coastal community at the northern edge of the Palm Beach metro, home of Roger Dean Chevrolet Stadium (spring training) and the Jonathan Dickinson State Park — draws its municipal water supply from the Surficial Aquifer (Anastasia Formation) and deeper Floridan Aquifer via the Town of Jupiter Utilities Water Division, pumping from north Palm Beach County coastal aquifer wells. Water hardness in Jupiter reaches 249.5 mg/L — classified as very hard.
Jupiter's very hard supply reflects the north Palm Beach County coastal aquifer's natural carbonate geology without reverse osmosis treatment. The Anastasia Formation (Pleistocene coquina — shell hash and calcareous reef limestone) in northern Palm Beach County is one of the most reactive calcareous formations in coastal Florida. The deeper Floridan Aquifer System (Eocene Avon Park Limestone and Ocala Group Limestone — thick, pure marine carbonate formations of the Florida Platform) contributes additional dissolved calcium when blended. Unlike some Palm Beach County communities that apply RO treatment to reduce natural aquifer hardness, Jupiter relies on conventional treatment — maintaining the natural 249.5 mg/L very hard aquifer chemistry in the finished supply.
At 249.5 mg/L, Jupiter residents face significant hard water challenges. Scale deposits form rapidly on faucet aerators, showerheads, shower glass, and tile — monthly descaling with citric acid solution is essential maintenance. Town of Jupiter Utilities Water Division consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Surficial Aquifer (Anastasia Limestone and Hawthorn Group) via the Town of Jupiter Utilities Water Division — the Palm Beach County northern Atlantic coastal zone Anastasia Formation and the Floridan Aquifer System (Eocene Avon Park and Ocala Limestone) of northern Palm Beach County; very hard supply at 249.5 mg/L — reflecting the naturally hard north Palm Beach County coastal aquifer.
