What Makes Gardere's Water Unique?
Local geology and source profile
Gardere, Louisiana, in East Baton Rouge Parish — an East Baton Rouge Parish unincorporated community adjacent to Baton Rouge and Port Allen in south-central Louisiana — receives its water from the Baton Rouge Water Company, drawing from the Mississippi River through the south Louisiana distribution.
The moderately hard 115.5 mg/L hardness and TDS of 256.2 mg/L reflect the East Baton Rouge Parish supply's moderate Mississippi River character — the Cretaceous Selma Chalk and Quaternary Gulf Coast alluvium contribute calcareous mineral content from the lower Mississippi River's extensive drainage of the Gulf Coastal Plain (compare Baton Rouge LA: 112/248 in East Baton Rouge Parish comparable; Port Allen LA: 118/264 in West Baton Rouge Parish comparable; Gardere consistent moderate from the same East Baton Rouge Parish Mississippi River Cretaceous calcareous supply). The Mississippi River at Baton Rouge — Cretaceous Selma Chalk (calcareous — primary hardness contributor), Quaternary Gulf Coast alluvium (calcareous — secondary contributor), and Holocene Mississippi River alluvium (calcareous — TDS contributor).
At 115.5 mg/L with TDS 256, Gardere's water is moderately hard — mild scale buildup. Semi-annual descaling is appropriate. The PFAS level of 10.6 ppt is very high — a certified filter with PFAS removal is strongly recommended. Review the Baton Rouge Water Company's annual water quality report.
Geology & Source: Gardere in East Baton Rouge Parish draws from the Baton Rouge Water on the Mississippi River (East Baton Rouge Parish, south Louisiana) — the Mississippi River at Baton Rouge draws from Cretaceous Selma Chalk (calcareous) and Quaternary Gulf Coast alluvium (calcareous) — Louisiana East Baton Rouge Parish Mississippi River Cretaceous calcareous supply produces moderately hard water at 115.5 mg/L with TDS 256.2 mg/L.
