What Makes Anderson's Water Unique?
Local geology and source profile
Anderson, South Carolina, the Anderson County seat — a major northwest South Carolina Upstate city (Anderson is the Anderson County seat — one of the most important Upstate South Carolina cities in the Greenville–Spartanburg–Anderson metropolitan area; Anderson is known as the 'Electric City' (Anderson was the first city in the southeastern United States to have commercial electric power, in 1897 — generated by the Portman Shoals dam on the Rocky River; the nickname 'Electric City' has been part of Anderson's identity for over a century)); Anderson is the home of Anderson University (a significant South Carolina Baptist university with growing programs in business, nursing, and arts), home of AnMed Health (the regional healthcare system for Anderson County), a diverse Anderson County community with a significant African-American, textile-heritage, and working-class to middle-class population, adjacent to Greenville and Clemson in the northwest South Carolina Upstate corridor — draws its municipal water supply from Lake Hartwell via the City of Anderson Water and Sewer Division. Water hardness in Anderson measures 63 mg/L — classified as moderately soft.
Anderson's moderate softness reflects the northwest SC Anderson County Savannah River Piedmont watershed's calcareous-poor Blue Ridge geology. The Lake Hartwell watershed drains the Precambrian Blue Ridge gneiss (calcareous-poor). City of Anderson treatment produces the moderately soft 63 mg/L.
With hardness at 63 mg/L, Anderson residents enjoy moderately soft water. City of Anderson Water and Sewer Division consistently delivers water meeting all South Carolina DHEC and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Lake Hartwell (Savannah River watershed) via the City of Anderson Water and Sewer Division — the Anderson County northwest SC Upstate Anderson corridor (Precambrian calcareous-poor Blue Ridge gneiss — the calcareous-poor northwest SC Savannah River Piedmont watershed; effective treatment); moderately soft supply at 63 mg/L in Anderson County.
