What Makes Loganville's Water Unique?
Local geology and source profile
Loganville, Georgia, in Walton County — a Walton County city adjacent to Monroe and Auburn east of Atlanta in the Atlanta metro area — receives its water from the City of Loganville Water Department or Walton County Water Authority, drawing from a local reservoir on the Apalachee River watershed through the northeast Georgia distribution.
The moderately hard 110 mg/L hardness and TDS of 230.4 mg/L reflect the Walton County supply's moderate Piedmont character — the Precambrian Piedmont Gneiss is largely insoluble but Cambrian Hillabee Formation schist and surface weathering of northeast Georgia Piedmont terrain contribute modest calcareous mineral content (compare Monroe GA: 107/223 in Walton County comparable; Auburn GA: 112/237 in Walton County comparable; Loganville consistent moderate from the same Walton County Walton County reservoir Precambrian insoluble supply). The Apalachee watershed — Precambrian Piedmont Gneiss (insoluble — primary dilutant), Cambrian Hillabee Formation (slightly insoluble — secondary dilutant), and Quaternary Piedmont alluvium (slightly calcareous — minor TDS).
At 110 mg/L with TDS 230, Loganville's water is moderately hard — mild scale buildup in appliances. Semi-annual descaling is appropriate. The PFAS level of 6.5 ppt warrants a certified drinking water filter. Review the City of Loganville's annual water quality report.
