What Makes Manchester's Water Unique?
Local geology and source profile
Manchester, Tennessee, in Coffee County — the Coffee County seat adjacent to Tullahoma and McMinnville on the Duck River in central Tennessee — receives its water from the City of Manchester Water Department, drawing from the Duck River through the central Tennessee distribution.
The moderately hard 115 mg/L hardness and TDS of 197.4 mg/L reflect the Coffee County supply's moderate Highland Rim character — the Mississippian Fort Payne Chert and Warsaw Limestone are slightly calcareous-calcareous formations in the Tennessee Highland Rim, contributing moderate dissolved mineral content from the Duck River's limestone corridor (compare Tullahoma TN: 112/190 in Coffee County comparable; McMinnville TN: 118/205 in Warren County comparable; Manchester consistent moderate from the same Coffee County Duck River Mississippian calcareous supply). The Duck River at Coffee County — Mississippian Fort Payne Chert (slightly calcareous — primary dilutant), Mississippian Warsaw Limestone (calcareous — primary hardness contributor), and Quaternary Duck River alluvium (calcareous — minor TDS).
At 115 mg/L with TDS 197, Manchester's water is moderately hard — mild scale buildup. Semi-annual descaling is appropriate. The PFAS level of 3.8 ppt is moderate — a certified drinking water filter provides added protection. Review the City of Manchester's annual water quality report.
Geology & Source: Manchester in Coffee County draws from the Manchester Water on the Duck River supply (Coffee County, central Tennessee) — the Cumberland Plateau at Coffee County draws from Mississippian Fort Payne Chert (slightly calcareous) and Mississippian Warsaw Limestone (calcareous) — Tennessee Coffee County Duck River Mississippian calcareous supply produces moderately hard water at 115 mg/L with TDS 197.4 mg/L.
