Sherrard, IL 2025 Consumer Confidence Report

The original annual drinking-water report. Every number on the Sherrard, IL water quality page is pulled from this document.

The Sherrard, IL figures for 2025 come from EPA's national Safe Drinking Water database (SDWIS / ECHO) — not a single utility-published PDF. Every value on the Sherrard, IL water quality page is transcribed from that public dataset, and you can verify it against the same source below.
