What Makes Aberdeen's Water Unique?
Local geology and source profile
Aberdeen, South Dakota, the Brown County seat — a major north-central South Dakota regional center (Aberdeen is the Brown County seat and one of the most important cities in South Dakota — the third-largest city in the state and the regional center for northeastern South Dakota and the James River Valley; Aberdeen is known as the 'Hub City' (Aberdeen serves as the retail, medical, and service hub for a large radius of northeastern South Dakota and neighboring North Dakota and Minnesota farmland); Aberdeen is home of Northern State University (NSU — a comprehensive state university known for its education and business programs; NSU is one of the most important higher education institutions in northeast South Dakota)), home of the Dacotah Prairie Museum (one of the most significant natural history and cultural history museums in the Dakotas), birthplace of L. Frank Baum (the author of 'The Wonderful Wizard of Oz' — L. Frank Baum lived in Aberdeen from 1888 to 1891, and he is honored in Aberdeen's Oz-themed local lore), a diverse Brown County community with a significant agricultural and Scandinavian-heritage population — draws its municipal water supply via the City of Aberdeen Water Division. Water hardness in Aberdeen measures 269.5 mg/L — classified as very hard.
Aberdeen's very hard supply reflects the north-central South Dakota James River glacial basin's highly calcareous character. The James River Valley aquifer draws from the Pleistocene calcareous glacial till (highly calcareous — glacial deposits over Cretaceous Pierre Shale). Very limited softening produces the very hard 269.5 mg/L.
At 269.5 mg/L, Aberdeen residents face significant hard water challenges. Regular water softeners and descaling are strongly recommended. City of Aberdeen Water Division consistently delivers water meeting all South Dakota DENR and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the James River Valley Basin (Aberdeen aquifer) via the City of Aberdeen Water Division — the Brown County north-central South Dakota Aberdeen corridor (Cretaceous calcareous Pierre Shale and Pleistocene calcareous glacial till and lacustrine — the extremely calcareous north-central South Dakota James River glacial basin; very limited softening); very hard at 269.5 mg/L in Brown County.
