What Makes South Venice's Water Unique?
Local geology and source profile
South Venice, Florida, in Sarasota County — an unincorporated Sarasota County community adjacent to Venice and Osprey on the west-central Florida Gulf Coast — receives its water from Sarasota County Utilities, drawing from the Floridan Aquifer (Sarasota County) through the west-central Florida Gulf Coast distribution.
The very hard 258 mg/L hardness and very high TDS of 791.7 mg/L reflect the west-central Florida Sarasota County Floridan Aquifer's very hard evaporitic character — harder than the Hillsborough County communities (Fish Hawk: 247.5 mg/L) and consistent with other Sarasota County deep Floridan draws. The Floridan Aquifer at Sarasota County — Eocene Avon Park Formation (calcareous and evaporitic — primary hardness and TDS contributor), Oligocene Suwannee Limestone (calcareous — secondary contributor), and Eocene Ocala Limestone (calcareous).
At 258 mg/L with TDS 791, South Venice's water is very hard. A water softener is strongly recommended and a reverse osmosis system is essential for drinking water. Scale builds very rapidly on surfaces and appliances. The PFAS level of 10.7 ppt warrants a certified reverse osmosis drinking water filter — Venice Municipal Airport (Sarasota County — AFFF) and the Sarasota County Gulf Coast industrial corridor contribute to South Venice's elevated readings.
Geology & Source: South Venice in Sarasota County draws from the Sarasota County Utilities on the Floridan Aquifer (Sarasota County, west-central Florida) — the Floridan Aquifer at Sarasota County is developed in Eocene Avon Park Formation (calcareous-evaporitic) and Oligocene Suwannee Limestone (calcareous) — Florida Sarasota County Floridan Aquifer Eocene calcareous-evaporitic produces very hard water at 258 mg/L with TDS 791.7 mg/L.
