What Makes Opelika's Water Unique?
Local geology and source profile
Opelika, Alabama, the Lee County seat — a major east Alabama university region city (Opelika is the Lee County seat — a significant east Alabama city in the Auburn–Opelika metro area; Opelika and Auburn together form one of the most significant small-city university metros in the South; Opelika is adjacent to Auburn University (one of the most important land-grant universities in the Southeast — Auburn is particularly known for its engineering, agriculture, veterinary medicine, and pharmacy programs; the Auburn–Alabama football rivalry is one of the most passionate college football rivalries in the United States)), a diverse Lee County community with a significant African-American, working-class, and academic community population, home of a significant Downtown Opelika revitalization (Downtown Opelika has transformed since the 2000s into one of the most vibrant small-town downtown districts in Alabama, with restaurants, shops, and breweries), adjacent to Auburn in the Lee County Auburn–Opelika metro corridor — draws its municipal water supply via the Opelika Water Works Board. Water hardness in Opelika measures 48 mg/L — classified as very soft.
Opelika's very soft supply reflects the east Alabama Lee County Piedmont crystalline watershed's calcareous-poor geology. The Lake Saugahatchee watershed drains the Precambrian Alabama Piedmont metamorphic (calcareous-poor crystalline). Opelika Water Works produces the very soft 48 mg/L.
With hardness at 48 mg/L, Opelika residents enjoy very soft water. Opelika Water Works Board consistently delivers water meeting all Alabama ADEM and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Opelika Water Works (local aquifer and Lake Saugahatchee) via the Opelika Water Works Board — the Lee County east Alabama Piedmont Opelika corridor (Precambrian calcareous-poor Alabama Piedmont metamorphic — the extremely calcareous-poor east Alabama Piedmont crystalline watershed; excellent treatment); very soft supply at 48 mg/L in Lee County.
