What Makes Taylorville's Water Unique?
Local geology and source profile
Taylorville, Illinois, in Christian County — the Christian County seat adjacent to Morrisonville and Pana on the Sangamon River in central Illinois — receives its water from the City of Taylorville Water Department, drawing from the Sangamon River through the central Illinois distribution.
The very hard 243.5 mg/L hardness and high TDS of 592.5 mg/L reflect the Christian County Sangamon River supply's very hard calcareous character — the Pennsylvanian Carbondale Formation and Mississippian Salem Limestone are highly calcareous formations in the central Illinois Corn Belt, and the Sangamon River acquires substantial dissolved mineral content from its extensive limestone and coal-measure drainage (compare Morrisonville IL: 239/581 in Christian County comparable; Pana IL: 247/603 in Christian County comparable; Taylorville consistent very hard from the same Christian County Sangamon River Pennsylvanian calcareous supply). The Sangamon watershed — Pennsylvanian Carbondale Formation (calcareous — primary hardness contributor), Mississippian Salem Limestone (highly calcareous — secondary contributor), and Quaternary Sangamon alluvium (calcareous — TDS contributor).
At 243.5 mg/L with TDS 593, Taylorville's water is very hard — a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 8.5 ppt is elevated — a certified drinking water filter with PFAS removal is recommended. Review the City of Taylorville's annual water quality report.
