What Makes Blytheville's Water Unique?
Local geology and source profile
Blytheville, Arkansas, in Mississippi County — the Mississippi County seat adjacent to Manila and the Missouri border in the northeast Arkansas Mississippi Delta — receives its municipal water from the Blytheville Water Division, drawing from the Mississippi River Alluvial Aquifer (Mississippi County) through the northeast Arkansas water treatment system.
The soft 74.5 mg/L hardness and TDS of 124 mg/L reflect the northeast Arkansas Mississippi Alluvial Aquifer's near-insoluble Holocene floodplain character — very soft by Arkansas standards and consistent with other Mississippi Delta alluvial communities (West Memphis: ~72 mg/L; Jonesboro: ~76 mg/L). The Mississippi River Alluvial Aquifer at Mississippi County is developed in Quaternary (Holocene) alluvial sand and gravel (near-insoluble — derived from eroded mixed sediment transported by the Mississippi and Ohio Rivers, primarily insoluble siliceous sand). The low-solubility alluvial aquifer produces the soft northeast Arkansas supply.
At 74.5 mg/L, Blytheville's water is soft — light scale forms slowly in appliances, dishwashers remain efficient, and bathroom fixtures need occasional cleaning. Semi-annual descaling is appropriate. The PFAS level of 3.0 ppt is low — Blytheville Air Force Base (Mississippi County — now Arkansas Aeroplex, legacy AFFF) contributes to background PFAS readings, though the level remains modest.
