What Makes Woodstock's Water Unique?
Local geology and source profile
Woodstock, Georgia, in Cherokee County — a major north Atlanta suburban community (Woodstock is a significant Cherokee County city — one of the fastest-growing communities in Georgia and one of the most rapidly expanding north Atlanta suburban communities; Woodstock has grown dramatically since the 1990s as the Atlanta metro has expanded northward along the I-575 corridor into Cherokee County; Woodstock is known for its charming historic downtown (one of the most active small-town downtowns in the Atlanta suburbs — with excellent restaurants, boutique retail, craft breweries, and live music venues) and its excellent Cherokee County school system), a diverse Cherokee County community with a primarily working-class and middle-class suburban family population (with increasing affluence and diversity as Atlanta suburbs have expanded), adjacent to Canton and Ball Ground in the north Cherokee County corridor, and one of the most vibrant north Atlanta suburban communities — draws its municipal water supply from the Little River via the City of Woodstock Water Division. Water hardness in Woodstock measures 94.5 mg/L — classified as moderately soft.
Woodstock's moderate softness reflects the north Georgia Cherokee County Blue Ridge foothills watershed's calcareous-poor geology. The Little River at Woodstock–Cherokee County drains the Precambrian Georgia Blue Ridge gneiss and schist (calcareous-poor crystalline). City of Woodstock treatment produces the moderately soft 94.5 mg/L.
With hardness at 94.5 mg/L, Woodstock residents enjoy moderately soft water. City of Woodstock Water Division consistently delivers water meeting all Georgia EPD and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Little River (Lake Allatoona watershed) via the City of Woodstock Water Division — the Cherokee County north Atlanta suburban Woodstock corridor (Precambrian calcareous-poor Blue Ridge Province gneiss — the calcareous-poor north Georgia Cherokee County Blue Ridge foothills watershed; effective treatment); moderately soft supply at 94.5 mg/L in Cherokee County.
