St. Louis sits on Mississippian limestone formations that extend hundreds of feet below ground level. Water percolating through this carbonate bedrock dissolves calcium and magnesium, creating the mineral-rich groundwater that feeds private wells and municipal supply systems. The advantages of water softening systems become critical in this geology. Areas like South St. Louis, Affton, and Lemay experience hardness levels exceeding 15 grains per gallon. The Missouri River surface water treatment plants reduce hardness through lime softening, but treated water still measures 8 to 12 grains per gallon. The hard water treatment benefits include protecting copper and PEX supply lines from mineral scaling that reduces water pressure and flow capacity over time.
