What Makes Greenville's Water Unique?
Local geology and source profile
Greenville, North Carolina, in Pitt County on the Tar River at the edge of the Coastal Plain — home of East Carolina University — draws its municipal water supply from the Tar River via the City of Greenville Utilities Commission (GUC), operating a raw water intake on the Tar River in Pitt County. The Tar River at Greenville has transitioned from the North Carolina Piedmont to the Coastal Plain zone. Water hardness measures 94.5 mg/L — classified as moderately soft.
Greenville's moderately soft supply reflects the Tar River watershed geology in eastern North Carolina. The upper Tar River drains the North Carolina Piedmont — the Carolina Terrane metagranite, metavolcanite, and meta-argillite (Precambrian–Ordovician) of the central Piedmont, with limited calcareous formations. The middle Tar crosses the Durham Triassic Basin (Triassic Newark Group — red sandstone and mudstone with calcite cement) and the Granville–Franklin County Piedmont transitional zone. By the time the Tar reaches Greenville at the Coastal Plain transition, it has accumulated moderate mineral content from the various Piedmont terranes. The dominance of siliceous Carolina Terrane in the upper watershed limits hardness to the moderately soft range.
With hardness at 94.5 mg/L, Greenville residents experience light to moderate scale accumulation. Faucet aerators and showerheads develop deposits slowly — bi-monthly cleaning with citric acid solution is sufficient. Dishwashers produce clean glassware. City of Greenville Utilities Commission consistently delivers water meeting all North Carolina DEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Tar River via the City of Greenville Utilities Commission (GUC) — the Tar River drains the North Carolina Piedmont Carolina Terrane metavolcanics, Durham Triassic Basin red beds, and North Carolina Coastal Plain Cretaceous and Tertiary calcareous formations; the Piedmont-to-Coastal Plain transition produces moderately soft supply at 94.5 mg/L in Pitt County.
