What Makes Alabaster's Water Unique?
Local geology and source profile
Alabaster, Alabama, in Shelby County — a major south Birmingham suburban community (Alabaster is a significant Shelby County community — one of the rapidly growing south Birmingham suburban cities in the US-280 corridor; Alabaster has experienced significant growth as Shelby County — consistently one of the fastest-growing counties in Alabama — has attracted Birmingham metro suburban expansion), home of Alabaster City Schools (a separate city school system that is one of the most highly regarded in the Birmingham metro area), a diverse Shelby County community with a significant professional, evangelical Christian, and growing Hispanic-American population, and a community in the rapidly developing I-65 south Birmingham suburban corridor — draws its municipal water supply from Lake Purdy (Cahaba River) via the Birmingham Water Works Board. Water hardness in Alabaster measures 38.5 mg/L — classified as very soft.
Alabastar's very soft supply reflects the Cahaba River watershed's calcareous-poor Piedmont geology. The Cahaba River (Lake Purdy) at Alabaster–Shelby County drains: the Precambrian Alabama Piedmont gneiss and schist (calcareous-poor crystalline basement); and the Cambrian–Ordovician Talladega Slate (calcareous-poor metamorphic belt). BWWB produces the very soft 38.5 mg/L.
With hardness at 38.5 mg/L, Alabaster residents enjoy very soft water. Birmingham Water Works Board consistently delivers water meeting all Alabama ADEM and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Cahaba River (Lake Purdy) via the Birmingham Water Works (BWWB) — the Shelby County central Alabama Birmingham south suburban Alabaster corridor (Precambrian calcareous-poor Alabama Piedmont gneiss and Cambrian–Ordovician calcareous-poor Talladega Slate — the calcareous-poor central Alabama Piedmont watershed; Birmingham Water Works south Shelby distribution to Alabaster zone); very soft supply at 38.5 mg/L in Shelby County.
