What Makes Gulf Shores's Water Unique?
Local geology and source profile
Gulf Shores, Alabama, in Baldwin County — a Baldwin County city adjacent to Orange Beach and Foley on the Gulf of Mexico in south Alabama — receives its water from Baldwin County Water Authority or Gulf Shores Water, drawing from the Perdido River and Coastal Plain supply through the south Alabama distribution.
The hard 162.5 mg/L hardness and TDS of 409.9 mg/L reflect the Baldwin County Coastal Plain supply's hard calcareous character — the Cretaceous Selma Chalk and Tertiary Wilcox Group are calcareous formations in the south Alabama Gulf Coastal Plain, with elevated dissolved mineral content from the shallow coastal aquifer zone (compare Orange Beach AL: 159/402 in Baldwin County comparable; Foley AL: 165/417 in Baldwin County comparable; Gulf Shores consistent hard from the same Baldwin County Perdido River Cretaceous calcareous supply). The Perdido watershed — Cretaceous Selma Chalk (calcareous — primary hardness contributor), Tertiary Wilcox Group (calcareous — secondary contributor), and Quaternary Gulf Coastal plain sediment (slightly calcareous — TDS contributor).
At 162.5 mg/L with TDS 410, Gulf Shores' water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 7.8 ppt is elevated — a certified drinking water filter with PFAS removal is recommended — the Baldwin County Gulf Coast military (NAS Pensacola area) sources contribute to elevated PFAS. Review Baldwin County Water Authority's annual report.
Geology & Source: Gulf Shores in Baldwin County draws from the Baldwin County Water on the Perdido River supply (Baldwin County, south Alabama) — the Perdido watershed at Baldwin County drains Cretaceous Selma Chalk (calcareous) and Tertiary Wilcox Group (calcareous) — Alabama Baldwin County Perdido River Cretaceous calcareous supply produces hard water at 162.5 mg/L with TDS 409.9 mg/L.
