What Makes Andover's Water Unique?
Local geology and source profile
Andover, Kansas, in Butler County — a Butler County city adjacent to Wichita and El Dorado in south-central Kansas — receives its water from the City of Andover Water, drawing from the Equus Beds aquifer or El Dorado Lake (Butler County) through the south-central Kansas distribution.
The hard 172 mg/L hardness and TDS of 410.2 mg/L reflect the south-central Kansas Butler County supply's hard calcareous character — between McPherson KS (162/381 on the Equus Beds) and El Dorado KS (262.5/710 on the harder Chase Permian limestone), Andover's intermediate hardness reflects a blend of Quaternary alluvial Equus Beds and Permian Chase Group limestone contacts. The Equus Beds-Chase at Butler County — Permian Chase Group limestone (highly calcareous — primary hardness contributor), Quaternary Equus Beds alluvium (calcareous — secondary contributor), and Cretaceous Greenhorn Limestone (calcareous — minor).
At 172 mg/L with TDS 410, Andover'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 2.8 ppt is relatively low — warrants routine monitoring but no urgent filtration.
Geology & Source: Andover in Butler County draws from the City of Andover Water on the Equus Beds aquifer or El Dorado Lake (Butler County, south-central Kansas) — the Equus Beds at Butler County are developed in Quaternary alluvium (calcareous) and Permian Chase Group limestone (highly calcareous) — Kansas Butler County Equus Beds-Chase Quaternary-Permian calcareous aquifer produces hard water at 172 mg/L with TDS 410.2 mg/L.
