About Peoria Soft Water
A plain-language guide to the very hard tap water in Peoria, Illinois.
Why it exists
Peoria, Illinois has very hard water and an older housing stock, and most softener advice online is written for somewhere else. This site pulls the local numbers from Illinois American Water's own reports, explains what they mean for a house, and says so when a cheaper option will do. It is not connected to any water utility, and it is not the Arizona city of the same name.
Where the numbers come from
Hardness comes from Illinois American Water's Peoria typical water quality sheet; sodium, lead, nitrate and PFAS from its 2025 Annual Water Quality Report; housing from the U.S. Census; rules from the Illinois Plumbing License Law and Plumbing Code. Prices come from Fixr, This Old House and HomeAdvisor and are labeled as national ranges on the Peoria, IL softener cost page.
