What Makes Addison's Water Unique?
Local geology and source profile
Addison, Texas, in Dallas County — a Dallas County town adjacent to Carrollton and Farmers Branch in the north Dallas suburb — receives its municipal water from Dallas Water Utilities, drawing from Lake Lewisville (Elm Fork Trinity River, Dallas County) through the north Dallas distribution system.
The moderately soft 84.5 mg/L hardness and TDS of 173.1 mg/L are significantly softer than the east Dallas Lake Ray Hubbard supply (Seagoville: 229.5 mg/L) — reflecting Lake Lewisville's position on the Elm Fork Trinity, which drains the Austin Chalk and Taylor Marl (moderately calcareous but less evaporitic than the Permian-influenced east Dallas watershed). The Elm Fork Trinity (Lake Lewisville) drains Cretaceous Austin Chalk (moderately calcareous — primary hardness contributor), Cretaceous Taylor Marl (moderately calcareous marine clay), and Cretaceous Woodbine Formation (slightly calcareous sandstone). The moderate Austin Chalk and Taylor Marl calcareous loading produces the softer north Dallas supply.
At 84.5 mg/L, Addison's water is moderately soft — light scale forms slowly in appliances, dishwashers remain efficient, and bathroom fixtures need occasional cleaning. Semi-annual descaling is appropriate. The PFAS level of 4.9 ppt warrants a certified drinking water filter — the Dallas County north Dallas corporate corridor and the Trinity River PFAS background contribute to Addison's readings.
