What Makes Greer's Water Unique?
Local geology and source profile
Greer, South Carolina — a major northwest South Carolina Greenville–Spartanburg suburban city (Greer is a significant city straddling the Greenville–Spartanburg county line — one of the most important Upstate South Carolina communities in the BMW Manufacturing US headquarters corridor; Greer is home of the Greenville–Spartanburg International Airport (GSP — the most important regional airport in the Upstate South Carolina and western North Carolina region; GSP serves the massive BMW Manufacturing plant corridor and the growing Greenville–Spartanburg–Anderson–Cherokee metro area)), home of BMW Manufacturing Co., LLC (BMW's only US manufacturing plant — the BMW Plant Spartanburg in Greer is the largest BMW factory in the world by production volume; the plant has been one of the most significant manufacturing investments in South Carolina's history since it opened in 1994), a diverse Greenville–Spartanburg community with a significant Hispanic-American and manufacturing professional population — draws its municipal water supply via the Greer Commission of Public Works. Water hardness in Greer measures 100.5 mg/L — classified as moderately hard.
Greer's moderate hardness reflects the northwest South Carolina Piedmont crystalline watershed's calcareous-poor character with distribution variation. The Pacolet River watershed at Greer drains the Precambrian Blue Ridge gneiss (calcareous-poor). Greer CPW treatment produces the moderate 100.5 mg/L.
At 100.5 mg/L, Greer residents encounter moderate scale accumulation. Monthly cleaning is recommended. Greer Commission of Public Works consistently delivers water meeting all South Carolina DHEC and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Lake Bowen and Lake Robinson (Pacolet watershed) via the Greer Commission of Public Works — the Greenville–Spartanburg Counties Upstate SC Piedmont Greer corridor (Precambrian calcareous-poor Blue Ridge gneiss — calcareous-poor Piedmont crystalline watershed; effective treatment); moderately hard at 100.5 mg/L in Greenville–Spartanburg Counties.
