What Makes Tarboro's Water Unique?
Local geology and source profile
Tarboro, North Carolina, in Edgecombe County — the Edgecombe County seat adjacent to Rocky Mount and Princeville on the Tar River in east-central North Carolina — receives its water from the Town of Tarboro Water Department, drawing from the Tar River through the east-central North Carolina distribution.
The soft 75 mg/L hardness and TDS of 121.2 mg/L reflect the Edgecombe County Tar River supply's soft Piedmont character — the Triassic Newark Formation and Precambrian Carolina Slate Belt are both largely insoluble formations in the eastern North Carolina Piedmont, contributing minimal dissolved minerals to the Tar River watershed (compare Rocky Mount NC: 73/116 in Nash/Edgecombe County comparable; Princeville NC: 76/125 in Edgecombe County comparable; Tarboro consistent soft from the same Edgecombe County Tar River Triassic insoluble supply). The Tar River watershed — Triassic Newark Formation (insoluble — primary dilutant), Precambrian Carolina Slate Belt (insoluble — secondary dilutant), and Quaternary Coastal Plain alluvium (slightly calcareous — minimal TDS).
At 75 mg/L with TDS 121, Tarboro's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 3.9 ppt is moderate and well-managed for east-central North Carolina. Review the Town of Tarboro's annual water quality report.
Geology & Source: Tarboro in Edgecombe County draws from the Tarboro Water on the Tar River (Edgecombe County, east-central North Carolina) — the Tar River watershed at Edgecombe County drains Triassic Newark Formation (insoluble) and Precambrian Carolina Slate Belt (insoluble) — North Carolina Edgecombe County Tar River Triassic insoluble supply produces soft water at 75 mg/L with TDS 121.2 mg/L.
