What Makes Harrison's Water Unique?
Local geology and source profile
Harrison, Arkansas, in Boone County — the Boone County seat adjacent to Berryville and Yellville in north Arkansas — receives its water from the Harrison Water Utilities, drawing from Lake Harrison (Boone County) through the north Arkansas distribution.
The hard 176 mg/L hardness and TDS of 393.1 mg/L reflect the north Arkansas Boone County Ozark Plateau supply's hard calcareous character — the Mississippian Boone Formation chert-limestone and Ordovician Cotter Dolomite contribute significant calcareous and dolomitic dissolution across the north Arkansas Ozark karst plateau, consistent with the Arkansas Ozark communities (compare Jonesboro AR on a softer alluvial draw; Harrison harder from the direct Ozark Plateau calcareous rock). The Lake Harrison watershed at Boone County — Mississippian Boone Formation (calcareous — primary hardness contributor from Ozark karst), Ordovician Cotter Dolomite (dolomitic — secondary contributor), and Devonian Clifty Formation (insoluble — dilutant).
At 176 mg/L with TDS 393, Harrison's water is hard. A water softener is recommended to prevent scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 5.0 ppt warrants a certified drinking water filter — the Boone County north Arkansas industrial corridor contribute to Harrison's readings.
Geology & Source: Harrison in Boone County draws from the Harrison Water Utilities on Lake Harrison (Boone County, north Arkansas) — the Lake Harrison watershed drains the Ozark Plateau (Mississippian Boone Formation chert-limestone — calcareous) and Ordovician Cotter Dolomite (dolomitic) — Arkansas Boone County Lake Harrison Mississippian-Ordovician calcareous dolomitic supply produces hard water at 176 mg/L with TDS 393.1 mg/L.
