Centerton Water Hardness & Quality Report (2026)

The Centerton Water & Sewer Department supplies the city of Centerton, Benton County, Arkansas, a region near the Missouri border. This utility procures fully treated surface water from the Benton-Washington Regional Public Water Authority. Their water originates from Beaver Lake, a significant reservoir managed by the US Army Corps of Engineers on the White River. Centerton does not operate any local treatment facilities; instead, water distribution is handled by the PWA's existing infrastructure. The Beaver Lake reservoir is situated within its watershed, which stretches across the Springfield Plateau of the Ozark Highlands.

The underlying geology is characterized by karst landscapes dominated by Paleozoic carbonate rock formations. These include Ordovician limestones such as the Everton and Plattin formations, as well as Mississippian-age Boone Chert. These soluble bedrock types are known to dissolve, releasing minerals into surface runoff and the reservoir waters. This geological process results in a moderately mineralized water supply, typical for Ozark surface water sources shaped by limestone bedrock weathering and influenced by seasonal rainfall.

As a soft water supply, Centerton's water presents minimal scaling challenges for household plumbing, water heaters, dishwashers, and washing machines. You'll find soap lathers easily, reducing the need for excess detergent, and fixtures tend to stay cleaner with less buildup. Occasional descaling with vinegar is generally sufficient for maintenance; a water softener isn't typically needed or advised. This approach helps retain the natural minerals that contribute to the water's taste and potential health benefits, while also avoiding added sodium. The utility's 2023 Consumer Confidence Report confirms adherence to all EPA primary drinking water standards. While Tapwaterdata.com noted some contaminants above health guidelines, all remained below legal limits (MCLs), and PFAS data was unavailable.
