What Makes Doraville's Water Unique?
Local geology and source profile
Doraville, Georgia, in DeKalb County β a DeKalb County city adjacent to Dunwoody and Chamblee in the northeast Atlanta suburbs β receives its water from DeKalb County Water & Wastewater, drawing from the Chattahoochee River through the northwest Georgia distribution.
The moderately hard 131.5 mg/L hardness and TDS of 318.4 mg/L reflect the DeKalb County Chattahoochee supply's moderate Piedmont character β the Precambrian Blue Ridge Gneiss is slightly calcareous metamorphic rock, while the Cambrian Weisner Formation contributes calcareous mineral content from its calcareous quartzite and metasandstone in the Georgia Blue Ridge (compare Dunwoody GA: 128/310 in DeKalb County comparable; Chamblee GA: 133/325 in DeKalb County comparable; Doraville consistent moderate from the same DeKalb County Chattahoochee River Precambrian supply). The Chattahoochee watershed β Precambrian Blue Ridge Gneiss (slightly calcareous β primary hardness contributor), Cambrian Weisner Formation (calcareous β secondary contributor), and Quaternary Chattahoochee alluvium (slightly calcareous β minor TDS).
At 131.5 mg/L with TDS 318, Doraville's water is moderately hard β mild scale buildup. Semi-annual descaling is appropriate. The PFAS level of 8.1 ppt is elevated β a certified drinking water filter with PFAS removal is recommended. Review DeKalb County Water's annual water quality report.
Geology & Source: Doraville in DeKalb County draws from the DeKalb County Water on the Chattahoochee River (DeKalb County, northwest Georgia) β the Chattahoochee watershed drains Precambrian Blue Ridge Gneiss (slightly calcareous) and Cambrian Weisner Formation (calcareous) β Georgia DeKalb County Chattahoochee River Precambrian supply produces moderately hard water at 131.5 mg/L with TDS 318.4 mg/L.
